This study was conducted during two successive seasons of2003/2004 and 2004/2005 at the Experimental Farm of OrnamentalHorticulture Department, Faculty of Agriculture, Cairo University to studythe effect of zinc at (0, 50 and 100 ppm) and some amino acids, tryptophanat (0, 50 and 100 ppm) and methionine at (0, 25 and 50 ppm) on growth,yield, oil production and chemical composition of caraway (Carum carvi,L.) plants. The results showed that zinc application had no significant effecton plant height in the first season, number of branches / plant, dry weight /plant and number of umbels / plant in both seasons. Whereas zinc at 50 ppmsignificantly increased plant height and dry weight / plant in the secondseason. Zinc at 50 and 100 ppm significantly increased fresh weight / plantin both two seasons , fruit yield / plant and oil yield/ plant in the second one.Zinc at 50 and 100 ppm insignificantly increased oil percentage in both twoseasons. Zinc at 50 and 100 ppm decreased limonine percentage in the oiland increased carvone percentage in the oil in both two seasons, totalcarbohydrates contents in both leaves and roots in the first season. Zinc at50 ppm increased total carbohydrates in fruits in the first season, while 100ppm increased it in leaves, fruits and roots in the second one.Tryptophan and methionine had a significant effect on plant freshand dry weights in both seasons. The most effective treatment wasmethionine application at 50 ppm. Tryptophan and methionine at 50 ppmgave the highest fruit yield / plant in the first and second seasons,respectively. Amino acids (tryptophan and methionine) insignificantlyincreased volatile oil percentage and oil yield / plant in the first season.Whereas, methionine at 25 ppm significantly decreased oil percentage in thesecond season. Methionine at the highest rate (50 ppm) decreased limoneneand increased carvone percentages in caraway essential oil in both seasons.Amino acids application increased total carbohydrates percentage in leavesin the first season, in fruits and roots in both two seasons.Interaction between zinc and amino acids (tryptophan andmethionine) had a significant effect on most vegetative growthcharacteristics, fruit yield / plant, oil percentage and oil yield / plant, andincreased limonine and carvone contents in the oil and total carbohydratespercentage in different plant organs.

A pot experiment was conducted in the two successive seasons2004/2005 and 2005/2006 at the Experimental Nursery of the OrnamentalHorticulture Department, Faculty of Agriculture, Cairo University, Giza,Egypt., with the aim of investigating the tolerance of sisal plant (Agavesisalana) to different levels of irrigation water salinity (0, 1000, 2000, 3000,4000, 5000, 6000 and 7000 ppm) as NaCl & CaC12 (1:1 by weight). Inaddition the effect of different fertilization treatments [unfertilized (control),organic fertilization (50 g compost / pot), chemical fertilizer (NPK) (2 g / pot),and compost plus NPK fertilizer], on reducing the unfavorable effects ofsalinity on vegetative growth and anatomical structure. The recorded resultsindicated that increasing salinity levels decreased most of the studiedparameters (plant height, number of leaves /plant, leaf area, leaf thickness,and dry weights of foliage and fibrous roots /plant). The anatomical studysupported and explained the recorded reduction of morphological traits underinvestigation due to salinity treatments. In general, it was noted that raisingthe level of salinity of irrigation water caused gradual decreases in means ofall the studied characteristics in both seasons, and these decreases wereremarkable at a salinity level of 7000 ppm. On the other hand, the fertilizationtreatments reduced, to some extent, the negative effect of salinity.

This investigation was carried out in 2004 and 2005 at Plant TissueCulture Laboratory, Agricultural Development System Project (ADSP),Ministry of Agriculture, to detect the effect of some media types, different levelsof some cytokinins and growth substances on some growth and rootingparameters of Anthurium scherzeranum, Schott in vitro as well as the influenceof NPK fertilization on plantlets transferred from in vitro to in vivo greenhouseconditions. The obtained results would be briefed in the following : Number ofshoots and leaves were significantly raised by N & N medium, supplementedwith 5.0mg/l for TDZ or BA individually. But, shoot length was significantlyincreased by MS medium free from TDZ or BA supplementation, whereas, freshweight / shoot tip showed varied responses towards the two cytokinins. The MSmedium supplied with TDZ at 2.0 mg/l or 5.0 mg BA/l supplemented to the N &N medium gave the heaviest fresh weight. Shoot length and fresh weight /shoottip were significantly increased by AgNO3 at 4-5mg/l or 2.0 mg GA3 /Lsupplemented to MS medium, individually or in combination. Number of shootsand leaves were significantly improved by 3.0 mg /L AgNO3, but they were notaffected by GA3 levels, individually; whereas 3.0 mg /L AgNO3 combined with1.0mg GA3 /L significantly resulted the highest record of these two characters.The half strength of MS, supplemented with 0.5 mg IBA /L combination,significantly gave the best growth parameters (shoot length, number of leavesand fresh weight). While root number and length were significantly increasedby 1.0 mg IBA/l added to 1/8 and 1/4 MS strengths, respectively. Plantstransferred from in vitro to in vivo under greenhouse conditions showed asignificant increase in number and length of shoots when fertilized withN:P:K:Mg (19:19:19:32) at rate of 4.0 g /pot, while number of leaves andflowers were significantly improved by 3.0 or 4.0 g /pot N: P: K (19:19:19),consecutively, applied in two equal doses.

An in vitro propagation was carried out at Plant Tissue CultureLaboratory, Agricultural Development System Project (ADSP), Ministry ofAgriculture, during the successive seasons of 2004/2005 and 2005/2006, tofind out the favorable methodology for in vitro propagation ofChrysanthemum morifolium, Ramat. The results could be summarized in thefollowing:The largest shoot length and number of leaves /shoot tip or nodeexplants occurred due MS medium supplemented with 0.1 mg /L TDZ, whereasshoot formation (%) was the best when shoot tips or nodes were subculture inWPM medium supplied with 0.1mg /L TDZ, but callus formation favoured the1.0 mg/l TDZ on WPM. Application GA3 at 1.0 mg /L to shoot tips, subcultureon MS medium supplemented with 1.0 mg BA /L., resulted the best shootlength, number of leaves as well as shoot and callus formation. Applying 0.5mg /L TDZ combined with 2.0 mg /L IAA to shoot tip explants gave the morenumber of leaves and shoot formation. While 2.0 mg /L IAA alone on shoottips resulted the longest shoots. The heaviest callus formation occurred onnode explants treated with 0.5 mg TDZ/l.Shoot tips subculture on MS medium supplemented with 1.0 mg/l BAunder light intensity of 1000 lux produced the larger number of leaves andshoot length.Callus formation was the heaviest on node explants under 1000 lux lightintensity. The largest number of leaves and shoot length occurred on shoottips subculture on MS medium supplied with 1.0 mg /L BA under 240C.But,callus formation was the best on node explants under 17 0C. Addingsucrose to MS medium supplemented with 1.0 mg /L BA was the bestcompared to fructose and glucose as sources of carbon in producing shootlength, number of leaves and callus formation. The highest values ofcharacters occurred due to 20 g /L sucrose combined with shoot tip explants.Shoot length and number of leaves/ shoot tip or node explants were the largestwhen treated with 1.0 mg /L BA, combined with 15 g. /L sucrose. Whereasnumber of shoots on shoot tips, or node explants was the highest at 1.0 mg /LBA with 10 g /L sucrose. The 1.0 mg /L IAA combined with 15 g /L sucrose ledto the heaviest callus formation. While root length was the longest by 0.1mg /LBA combined with sucrose at 10 g /L. MS medium at 1/2 strength resulted thelargest number of roots, root length and root formation, While full strength ofMS failed to induce roots .Reducing MS strength caused concomitant decreasein the growth; characters shoot length and number of leaves. MS salts mediumat full strength gave the largest growth characters.

Series of experiments were undertaken at Plant Tissue CultureLaboratory, Agricultural Development System Project (ADSP), Ministry ofAgriculture, during the two consecutive seasons of 2005 and 2006, todetermine the influence of different sterilization materials and time, types ofmedia, different levels of BA and NAA and sucrose concentrations on somegrowth and rhizome characters of common (ginger), (Zingiber officinale,Rosc.). The obtained results could be briefed in the following points: -Increasing the level of HgCl2 on NaOCl and time of immersing shoot tips, ledto gradual inhibition of survival and contamination (%).- Sterilization withmercuric chloride at 0.3% level for 5 minutes followed by 1.0% sodiumhypochlorite for 5 minutes also, inhibited contamination completely and 100%survival. - The best shoot number and root length were resulted by liquidmedia supplemented with BA at 3.0 and 1.0 mg/l, respectively. While, solidmedium free from BA gave the best shoot length and number of roots.- Controltreatment produced the highest length of shoot and root as well as number ofroots, but number of shoots was the largest due to 0.5 mg BA + 0.5 mg NAA/l.treatment. - Raising concentrations of sucrose, reduced survival (%)gradually. The 70 and 90g/l sucrose resulted the highest formation (%) andnumber of rhizomes.Under greenhouse conditions, the favourable size of rhizome, as well asthe levels of NPK fertilization were evaluated for growth and development ofcommon ginger, in the two seasons. Plant height, number of leaves and freshweights of vegetative growth and rhizomes, were increased progressively byincreasing the size of the planted rhizomes (cuttings) in the greenhouse. Thesize of rhizomes (40 – 50g) gave growth values more than double the values of20g rhizome. - In the greenhouse, raising N or K ratios increased graduallynumber of branches, leaves and roots, plant height ,root length and freshweight of vegetative growth and rhizomes.

A field experiment was carried out during the seasons of 2005 and 2006at Orman Botanical Garden, Giza, Egypt to study the effect of some scarificationtreatments on germination parameters, endocarp constituents and the quality ofdoum (Hyphaene thebaica, L. Mart.) seedlings.The results indicated that endocarp punching or removal treatmentsslightly improved characters of germination and seedlings quality, which weresignificant in some cases, specially for punching treatments, while clefting thebare endocarp reduced such parameters to the minimal values in most cases ofboth seasons. However, the previous three treatments didn’t obviously affectthickness, strength and chemical constituents of the bony endocarp. On the otherhand, soaking in concentrated H2SO4, specially for 6 hrs., significantly improvedgermination (%), germination velocity, mean germination rate, germination rateindex, vigour index and quality of the resulted seedlings; which assessed as firstleaf length, root branchlets number/ seedling and aerial parts and roots freshand dry weights. The least means for endocarp thickness, strength and chemicalconstituents were also referred to the acid scarification with concentratedH2SO4 treatments.Hence, soaking the bare seeds of doum (Hyphaene thebaica, L. Mart.) inconcentrated H2SO4 for 6 hrs. can be recommended as a simple, cheap andquick way for high germination percent and good quality of seedlings.

Two field experiments were conducted at the experimental farm of theInstitute Efficient Productivity, Zagazig University, located at Ghazala village,Sharkia Governorate. The aim of the study was to know effect of nitrogenfertilization levels and its splits on growth and yield of three rice cultivars. Theexperiments were conducted during 2005 and 2006 summer growing seasons.The tested cultivars were Giza 178, Sakha 103 and Sakha 104. Two nitrogenfertilizer levels 40 and 60 kg were split and applied at two, three and four equaldoses.The most important results were: the rice cultivars differed in theirgrowth, grain yield, yield components and quality characters. Where, Sakha 103was the superior in most characters and Sakha 104 in the second order.Increasing nitrogen fertilization levels from 40 to 60 kg N/fad increasedthe most yield components which led to significant increase in grain yield/fad.Meantime, rice grain quality was improved significantly with increasingnitrogen fertilizer level.Increasing of N splitting caused significant increases in growth, yield andyield components. Since four splits was the superior and three splits came in thesecond rank but two splits treatment was the latter in most characters. Ricegrain quality was not affected by nitrogen fertilizer splitting.Interaction effect between nitrogen fertilizer levels and its splitting wassignificant on number of unfilled grains/panicle, number of filled grains/panicleand grain yield/fad.

A general survey study of insect pollinators visiting Nigella sativa L.blossoms in Assiut region, showed that the collected insects belong to eightorders. Hymenopterous insects formed 56.38 %, Apis mellifera L. was themost common Hymenopterous, as it constituted 26.90 %. Insects of ordersColeptera, Diptera and Lepidoptera came in the second class, forming 16.21,16.13 and 15.98 % of the total insect count, respectively. While ordersNeuroptera, Odonata, Orthoptera and Hemiptera were poorly represented.Regarding seasonal activity of honeybee foragers on Nigella sativa L.fields, it was found that the ratio of pollen and nectar foragers was 60.60,39.34 %, respectively. Daily peak activity of pollen and nectar foragers wasdetected at 3 p.m.The mean weight of 1000 seeds resulted from honeybee pollinated andopen pollinated plots revealed a significant increase in comparison withinsect-excluded. The mean weight of seeds calculated per feddan was 782.7,760.8, 650.4 kg for honeybee pollinates plots, open pollinated and insectexcluded,respectively. Percentage of essential oil was nearly similar in threetreatments.

Department of Animal Production, Faculty of Agriculture, Sohag University, Egypt
The present study was carried out to investigate the influence offeeding levels from mating to day 10 of pregnancy on progesteronehormone concentration, gestation length, fertility rate, litter traits andmilk yield. Twenty seven New Zealand White (NZW) rabbit does, agedfrom 5.5 to 6.0 months with an average initial body weight (3.00±0.25 kg),were used in the present work. The rabbit does were divided into threefeeding level groups 9 in each. Rabbits were fed a pelleted diet containing2800 kcal /kg and 18% crude protein. The first group (G1) was kept as acontrol group and received 140g/day ration during the experimentalperiod. The second group (G2) and third group (G3) received 70g and280g/day ration, representing 50and 200 % of feed level as comparedwith control group, respectively .The results revealed that, plasma progesterone hormone levels at3 ,7 and 14 days of mating differed significantly (P<0.05) and (P<0.01)among the three feeding level groups, respectively . The level ofprogesterone hormone was the highest in G2, G1 and G3, respectively.Fertility rate was affected significantly (P<0.01) by the feeding levels,being higher (P<0.01) in G2, then G1 and G3, respectively. Gestationlength, litter size and weight at birth, 1, 2, 3 and 4 weeks of age wereinsignificantly affected. The highest (Pat 1st and 2nd weeks were recorded in does in G1, while at 3rd and 4thweeks of lactation in G3 . Distinctively, milk yield increased graduallyreaching the peak at 3rd week of lactation in all feeding level groups . Thedifferences were significant by (P<0.01) between the 1st and 2nd weeksof lactation.It could be concluded that rabbit does under fed restricted dietconditions up to 50% of control diet from mating to 10 day of pregnancyimproved their reproductive efficiency in NZW.

The effects of donors hormonal treatment and embryo developmental stageson the survival of vitrified rabbit embryos were examined. Thirty six virgin NewZealand White rabbit does aging 6-7 months were divided in two groups. Does inthe 1st group (n=24) were treated with intramuscular injection of 20 μg GnRH/doefor induction of ovulation and artificially inseminated. Does in the 2nd group(n=12) were treated with subcutaneous injection of 80 IU PMSG/doe and 68 h laterwith intravenous injection of 50 IU hCG/doe for the induction of superovulationand artificially inseminated following hCG administration. Eight and four doesfrom the 1st and 2nd groups respectively were slaughtered in each of 24-26, 48-50and 72-74 h after insemination for embryo collection. Embryos at variousdevelopmental stages were vitrified. Upon de-vitrification, embryos were evaluatedfor viability as indicated by the morphological appearance and subsequentdevelopment in culture medium for 48 h.The percentage of normal embryos vitrified and embryos post-thawing withmorphologically normal appearance recovered from GnRH treated does werehigher than that obtained from superovulated donors (93.05 vs. 77.43% and 75.86vs. 67.43%, respectively). Only 63 (36%) of 175 superovulated embryo vitrified wascleaved in vitro post-vitrification compared to 89 (51.15%) of 174 control embryos.No significant differences were observed among embryo developmental stages inthe percentage of vitrified normal embryos. The percentages of embryos recoveredpost-vitrification with morphologically normal appearance were significantly(P<0.05) higher in later developmental stages compared to earlier stages. The bestpercentage of embryos developed in vitro have been obtained after de-vitrificationat the early blastocyst stage, followed by that at compacted morulae and morulaestages, whereas the lower percentage were recorded with embryos vitrified at 2-and 4- cell stages. Markedly high in vitro development rates (84.85-92.31%) wereobtained in morulae, compacted morulae and early blastocyst stages in controlembryos compared to 63.33-81.48% in embryos produced through superovulation.These results show that treating donor with GnRH achieve the best embryos forcryopreservation and also rabbit embryos at morulae, compacted morulae andearly blastocyst stages are appear to be proper candidate stages forcryopreservation.

Sequential extraction technique of phosphorus using differentextractant solutions were carried out to separate various pools of soilphosphorus such as (I) labile (plant available) Pi, (2) inorganic P bound toFe and Al, (3) inorganic P bound to Ca and Mg, (4) organic P, and (5)residual P. The procedure were developed for natural amendments appliedin this study containing compost (C), phosphate Rock (PR), Citric acid (CA)in different combination treatments, to recognize plant available P in readilyavailable forms (water soluble and bicarbonate form), refractory forms(NaOH-P, Po, HCL Pi, residual-P). Moreover, the rate process of Preleased from these systems was also determined to evaluate the ratedistribution of P in different forms as affected by compost treatments andresidence time and subsequently P availability in such systems.The obtained results indicated that application of compost treated with15%PR (T3), the best treatment in overall experiment, increased theextractable phosphorus extracted with H2O (WS) compared with the othertreatments. The acidification of PR by citric acid at different rates of 2 and 4% treatments applied in sandy soil gradually increased the WS fractioncompared with control (PR) through the incubation periods. The higherreadily available P was particularly observed after 30 and 120 days of soilincubation period. For these available forms, data showed that theextractable fraction of P by sodium bicarbonate (the exchangeable form)varied significantly for the investigated treatments and time of incubation.The extractable fraction of P by NaOH gave the higher available valuesparticularly for T3 compared with other treatments. In HCl-P pool, resultsindicated that application of citric acid at rate of 2% was also increased thispool by about 12 % over control. Increasing rate up to 4% graduallyincreased this fraction by about 25 % particularly after 15 days ofincubation. Data observed that the extractable fractions of phosphorus byEDTA for the investigated treatments were varied according to treatmentapplied or incubation time of treatments; nevertheless higher values werenoticed again in T3. The application of kinetic study applied in thisexperiment showed that the concentration of P through the entire reactiontime was varied in different forms into two stages which representing526 EL-KHERBAWY ET ALdifferent mechanisms controlled P distribution and P availability throughthe entire reaction time.

The extremely hazardous effects of the local insecticidal alternativesnamely; mineral oil CAPL-2; organic acid; i.e. citric acid as well asbiocides included profect evaluated against the predaceous insect; Scymnussyriacus Mars. Stages (egg, Larvae, pupae and adult) in comparable withthe conventional insecticide; Nuvacron. Four Experiments were carried outfor determination the hazardous effects of insecticidal alternatives andNavacron by using their recommend rates for controlling either aphid/firstlyfor determination of their ovicidal effect secondly, determination of theirtoxic effect on the larval stage, the third one for determination their efficacyagainst pupae and the fourth experiment was aimed to determine their toxiceffect on the adult stage. Two methods were used for the evaluation the typestage of the natural enemy, where in case of non-feeding stages included eggand pupae were exposed directly spraying with recommend rats of thecomponents used for those stages. Concerning feeding stages; i.e. larvaeand adult was introduced to the leaves were sprayed with the recommendedrates of the tested materials forementioned previously. The obtained resultsindicated that the conventional insecticide ie. Nuvacron was the most mosthazarvdous treatment against all stages of the predaceus insect Scymnussyriacus Mars. While the citric acid was the most safe component followedby the tested biocide; as well as CAPL-2. It could be concluded that theinsecticidal alternatives should be used in the IPM programs for controllingthe cotton aphids in the objective of keeping the natural enemies to do theireffects as control agent.

Two experiments were carried out at experiments farm station,National Research Center, at Shalakan, El-Kanater El-Khairya, KalubiaGovernorate, Egypt, for two successive seasons of 2004/2005 and2005/2006 to study the response of Sideritis montana L. plant to differentsources of nitrogen, (i.e. Urea, compost and Azotobacter at the levels 50,75and 100N unit), with three different sowing dates (30th September, 30thOctober and 30th November).Data indicated that all nitrogen sources increased vegetative growth(plant height, number of branches/plant, herb fresh and dry weight) andchemical composition (essential oil % and yield/plant, flavonoides %, totalchlorophyll content, carotenoids content and carbohydrate %) significantly,compared to untreated plants. Moreover, raising the N level resulted insteady significant increases in vegetative growth parameters and chemicalcomposition. In general, the second sowing date (30th October) was themost effective date on promoting the vegetative growth. It can berecommended that for the best vegetative growth and flavonoides content ofSideritis montana L. plants, the seeds should be sown on 30th October,while for the highest essential oil % and yield, plants should be sown on 30thSeptember, and the plants should be supplied with the highest level ofcompost plus Azotobacter in both sowing dates.

This study was carried out at the Ornamental Horticulture Department, Faculty ofAgriculture, Cairo University, during the two successive seasons of 2005 and 2006 withthe aim of investigating the effect of preservative solutions and holding periods on thelongevity, physiological characteristics and chemical composition of rose flowers (Rosahybrida, L. cv. First Red) stored for 14 days at 2° C. Rose flowers were pulsed in asolution containing kinetin at a concentration of 25 ppm + 8-Hydroxyquinoline at 150ppm for 24 hours before storing for 14 days at 2º C and a relative humidity (RH) of 85-90%. After that, the flowers were placed in jars containing one of the followingpreservative solutions: (1) distilled water, (2) 2% sucrose (Suc) + 200 ppm 8-hydroxyquinoline(8-HQ) + 250 ppm citric acid (CA), (3) 2% Suc+ 200 ppm 8-HQ + 250 ppmCA + 2 mM 2-mercaptoethanol, (4) 2% Suc + 200 ppm 8-HQ + 250 ppm CA + 0.1%Ca(NO3)2 , (5) 2% Suc + 200 ppm 8-HQ, (6) 2% Suc + 200 ppm 8-HQ + 100 ppmCuSO4 or (7) 2% Suc + 200 ppm 8- HQ + 1 mM boric acid.The results showed that the rate of increase in the flower diameter was decreasedsteadily with time, also fresh weight of flowers and the rate of daily absorption of thepreservative solution were decreased after the 3rd day of holding the flowers in thepreservative solutions, while the respiration rate was decreased after the 6th day. On thecontrary peroxidase activity in the necks of flowers and stem bases were higher on the12th day than on the 6th day. The total soluble sugars in the petals and leaves, theanthocyanins and carotenoids in the petals, as well as the total chlorophylls andcarotenoids in the leaves, were lower on the 12th day than on the 6th day of holding theflowers in the preservative solutions, whereas the total soluble phenols content in thepetals and leaves were higher on the 12th day than on the 6th day.Most of the tested preservative solutions increased the flower quality and improvedphysiological characteristics and chemical composition, compared to distilled water (thecontrol). The preservative solution containing 2% Suc + 200 ppm 8-HQ +2 mM 2-mercaptoethanol + 250 ppm CA can be recommended for holding Rosa hybrida cv.First Red flowers after storage for 14 days on 2° C, as it gave the best results in termsof flower quality, physiological characteristics and chemical compositions, whereas usingthe preservative solution containing 2% Suc + 200 ppm 8-HQ + 100 ppm CuSO4 resultedin the lowest quality, as well as unacceptable physiological characteristics and chemicalcompositions.

A pot experiment was carried out during two successiveseasons,2005and 2006 in the greenhouse , at Ornamental HorticultureDepartment, Faculty of Agriculture, Cairo University, to study the effect ofgrowing media on growth and chemical composition of croton plant.Generally, growing the croton plant cv. "Gold Star" in a mixture ofsand+ peatmoss + clay, sand + peatmoss+ vermiculite or sand+ peatmoss +perlite resulted in the tallest plants with the greatest number of leaves and thelargest leaf area. The mixture of sand + peatmoss +clay as well as sand+peatmoss +perlite significantly increased stem diameter. Most of growingmixtures had a favorable effect on increasing the number of branches of thecroton as compared with the mixtures of sand+ peatmoss+ sawdust and sand+ peatmoss + dried leaves. The fresh and dry weights of leaves and stemswere heavier in the mixtures of sand + peatmoss +clay and sand +peatmoss+vermiculite. The mixtures of sand +peatmoss +sawdust and peatmoss+perlite, sand +peatmoss +clay increased the root length and fresh and dryweights of roots of the croton plants.The mixtures of sand + peatmoss + perlite, sand + peatmoss + clayand sand + peatmoss + vermiculite were the most effective media inincreasing the contents of both chlorophyll–a and chlorophyll–b. The highestvalue of the carbohydrates content in the leaves of croton plants was recordedwith the mixture of sand + peatmoss + vermiculite, The stem content ofcarbohydrates reached the highest value in sand + peatmoss + clay mixture.Using sand + peatmoss + perlite increased the accumulation of nitrogen in theleaves, stems and roots. Adding vermiculite, clay or perlite to sand + peatmossmixtures had favorable effect on increasing the K content in the leaves of thecroton plant, whereas the mixture of sand + peatmoss + perlite increased Kcontent in the stems and roots.

STUDIES ON PLUM (PRUNUS DOMESTICA) L. TREES AFFECTING THEIR RESISTANCE TO APHID HYALOPTERUS ARUNDINIS FABR.
Hassan Salem

Plant Protection Research Institute, Agricultural Research Center,Giza, Egypt
The chemcial analysis of spring and autumn leaves of plumes can giveimportant information for the relation between chemical components andthe susceptibility of plum leaves to be infested with aphid, so, spring andautumn leaves from the local plum trees were subjected to chemicalanalysis to isolate the flavonoid compound such as coumarin, hydroxycoumarin and Oxy. coumarin. Results revealed that spring and summerleaves contained either hydroxy or oxy-Coumarin. Whereas the autumnleaves contain coumarin when commercal coumarins were tested againstadults of the Aphid Hyalopterus arundinis Fabr.Through stretched membrane on synthetic diet, coumarin gave feedingstimulants at 25molar whil the other two compounds (HC and OC)changed the effect of the molecule aphid feeding from stimulatory toinhibitory. Hydroxy coumarin was very feeding inhibitor at 3 molars whileOxy-Coumarin was lethal at l molar that may, in part explain why aphidharboured abundantly plum trees in autumn, since the leaves arecontaining coumarin which used as an antifrost agent and protected themwith their afids from severe cooling during winter the spring and summerleaves have been containing hydroxy and oxy-Coumarin. In Egypt aphidsprotect themselves against the low temperature of winter by feeding onHandaquoq plants and sweet clover in which they have coumarin.

The present study was included two trails. The first trail was startedfrom sexual maturity at 6 months of age up to fulfillment two parities in orderto evaluate the effects of treatment with either oxytetracycline or enrofloxacinon some physiological parameters, as well as , the reproductive performanceof female Bouscat rabbits, In this respect, 36 does were randomly divided intothree groups. The first group was used as a control group and wassubcutaneously injected with saline solution (1 ml of 0.9 % NaCl). The secondand three groups were subcutaneously injected with 50 mg oxytetracyclineand 2.5 mg enrofloxacin/ kg body weight, respectively. The 2nd trail, lasted 8weeks (from weaning at 5 weeks up to 13 weeks of age) in order to evaluatethe effects of injection of some antimicrobials (tetracycline and enrofloxacin)on productive performance of growing Bouscat rabbits . In this respect, 60weaning Bouscat rabbits (30 males and 30 females, 5 weeks old), as similarlyin the 1st part.Results showed that the live body weight was increased withoxytetracycline and decreased with enrofloxacin as compared to the control.Treatment with either oxytetracycline or enrofloxacin increased the totalnumber of RBCs after mating and decreased it during pregnancy, lactationperiod and at sacrifice. The WBCs of rabbits treated with oxytetracycline andenrofloxacin were significantly increased than the control group. The plateletscount of rabbits treated with oxytetracycline was decreased after mating andduring pregnancy and increased during lactation and at sacrifice. Inoxytetracycline-treated does, there was a slight increase in hemoglobinconcentration.The serum AST was significantly decreased in female rabbits treatedwith oxytetracycline one-week after the 1st injection, ALT was alsoinsignificantly decreased by treatment with oxytetracycline and enrofloxacinas compared with the control group. After the 1st injection; oxytetracyclineinsignificantly decreased the creatinine and significantly decreased ureaconcentration, while enrofloxacin increased the serum levels of bothcreatinine and urea. At sacrifice, the progesterone level was significantlyincreased by treatment with oxytetracycline and enrofloxacin. Estradiol levelsignificantly increased in both oxytetracycline and enrofloxacin-treated doesafter mating, during pregnancy and at sacrifice.Conception rate was significantly increased in doe rabbits treated witheither oxytetracycline or enrofloxacin as compared to that of the control. Thelitter size at birth was slightly increased after treatment with eitheroxytetracycline or enrofloxacin, and was increased significantly at 21 and 28days with both treatments. The litter weight at birth of treated rabbits withoxytetracycline was significantly improved followed by enrofloxacin ascompared with control group. Oxytetracycline and enrofloxacin treatmentssignificantly increased the daily milk yield at 1st, 2nd and 3rd week of lactationperiod of doe rabbits as compared to that of the control group. Bothoxytetracycline and enrofloxacin injections significantly increased theviability percentage during the period from birth to 21 and 28 days. Bothoxytetracycline and enrofloxacin treatments significantly increased the dailyweight gain from 5-9, 9-13 and 5-13 weeks of age intervals of growing rabbits.The feed intake of growing rabbits was insignificantly increased during5-9 and 5-13 weeks of age and insignificantly decreased during 9-13 weeks ofage in treated groups. The daily feed conversion was insignificantly decreasedduring the period from 5-9 weeks of age of growing rabbits after eitheroxytetracycline or enrofloxacin treatment, however, it was significantlyincreased during the period from 9-13 and 5-13 weeks of age.

The present study includes three points, i.e., wheat cultivarsusceptibility, seasonal fluctuation of mite species, associated predators andevaluation of certain control materials against mites on wheat plants.The susceptibility of the three wheat cultivars (Sakha 93, Giza 168 andGemiza 9) to investigation of mite species Petrobia tritici Kandeel, El-Naggarand Mohamed and two spotted spider mite, Tetranychus urtica) was inspectedduring the two successive seasons of 05/06 and 06/07 at Zagazig district. Theobtained results revealed that the Sakha 93 cultivar was more susceptible toP. tritici infestation. The relatively higher numbers ranging 9.37- 11.26 and2.142-8.18 mite/leaf were recorded for the two mite species during the twoseasons, respectively. The relatively lower mean numbers ranged 4.47-5.37and 1.76-4.47 mite/leaf were recorded on Giza 168, while the moderatenumbers of 6.36-8.47 and 2.08-4.7 mite/leaf were recorded on Gemiza 9cultivar for the two mite species during the two study seasons.The yield of test cultivar was found in contrast with infestation levels,where the relatively lower yield ranging 3.68-4.0 g/plant was recorded for themore susceptible cultivar, Sakha 93; while the highest yield ranging 6.0-6.02g/plant was recorded for the more tolerant cultivar, Gemiza 9 which infestedby moderate number of mites.The result of seasonal fluctuation of the mite species infested the threetested cultivars revealed that the population of P. tritici recorded 1-2 peaksduring the two seasons with the highest mean numbers of 28.0 and 34.33mite/leaf on Sakha 93 at the first weak of April during the two seasons,respectively. The two spotted spider mite recorded 3-4 peaks on the testedcultivars during the two seasons with highest peak of 26.0 mite/leaf on Sakha93 at early-April during the first season. During the second season, thehighest peak of 7.0 mite/leaf was recorded at the end of March on Gemiza 9.The relatively higher total predators number ranging 7.33-11.67 and3.0-6.33 individuals/plant were recorded in timing with the high number ofphytophagous mites on tested cultivars during the first and second seasons,respectively.As evaluation of toxicant materials results, the all tested materialsreduced the numbers of mites significantly compared with control with highestreduction percentages recorded for the convention pesticides followed byplant extracts and other materials.Regarding to reduction percentages, three groups were conducted, thefirst ranging 78.84-96.55 % (pesticides), 70.94-88.23 % (plant extracts) and45.24-69.93 % (bio-products) during the two study seasons. Therefore, itcould be concluded that the plant extracts and bio-products can be used ascontrol agents for mites IPM programs in wheat fields.

Seasonal abundance of the oleander aphid, Aphis nerii Boyer deFonscolombe and its associated parasitoids on duranta plants were studie inZagazig and Mansoura during the three seasons 2004/05, 2005/06 and2006/07. Obtained data revealed that:A. nerii infestation of duranta started by late September and earlyOctober, respectively. It continued to late March in the three season. Theaphid numbers ranged between 10.88-48.04, 9.40-38.16 and 8.44-39.52individuals/leaf, respectively in Zagazig during the three seasons. While, inMansoura the infestation started earlier in the first half of September. Itcontinued to early March. The aphid numbers ranged between 16.08-52.16,15.72-37.56 and 14.00-41.00 individuals/leaf, respectively during the threeseasons.In Zagazig, the aphid abundance showed three peaks in the threeseasons of study. The mean numbers of aphids/leaf was 25.64, 25.04 and22.75, respectively during the three seasons, meanwhile in Mansoura theaphid abundance showed three peaks in first season, four peaks in secondseason and two peaks in third seasons. The mean numbers of aphids/leafwere 26.63, 24.91 and 24.83, respectively during the three seasons.Five hymenopterous parasitoids, Diaeretiella rapae (M`Intosh),Aphidius sp. (Aphidiidae), (primary parasitoids) Pachyneuron sp.(Pteromalidae), Alloxysta sp. (Cynipidae) and Aphidencyrtus sp.(Encyrtidae) (Hyper parasitoids) were recorded..D. rapae was the most dominant one, where it occupied 86.68 and79.57 %, while, Aphidius sp. was 13.32 and 20.43 % in Zagazig andMansoura, respectively during the three seasons of study.Pachyneuron sp. occupied 52.13, 61.62 %, while Aphidencyrtus sp.was 26.95, 21.4% and Alloxysta sp. was 20.92 and 16.97 % in Zagazig andMansoura, respectively during the three season of study.Total means of parasitism rates of primary parasitoids; D. rapae andAphidius spp. were 9.77, 8.69, 12.66 % and 3.39, 7.32, 7.34 % in Zagazigand Mansoura during the three seasons, respectively.
