SOME PHYSIOLOGICAL PRODUCTIVE AND REPRODUCTIVE TRAITS OF INSHAS LOCAL STRAIN AS AFFECTED BY DIETARY ZINC SUPPLEMENTATION UNDER HOT SUMMER CONDITIONS IN EGYPT
A 2X4 factorial design experiment was performed including two sources of zinc (inorganic or organic). The inorganic Zn was provided as zinc oxide 72% and organic Zn was provided as Bioplex Zn, a chelated Zn proteinate that contained 10% Zn (Bioplex, Alltech Inc). The inorganic or organic zinc were added to the basal diet containing 22.21 mg zinc /Kg diet completed to 35(NRC, 1994), 70, 105 and 140 mg Zn / Kg diet. A total number of 240 laying hens and 24 cocks of Inshas strain (local strain) of 24 weeks old was used to study the effect of sources and levels of Zn addition to birds rations on their productive performance, reproductive traits, immune response to SRBC and economic efficiency. Birds were randomly distributed into eight equal groups (30 hens and 3 cocks each). Each group was subdivided into three replicates (10 hens and 1 cocks each) laying hens of each group nearly equal in average body weight (1430.55± 19.95) and average daily egg production. The experiment period extended from 24 to 36 weeks of age, during hot summer season (from June to September, 2008). The average minimum and maximum ambient temperatures ranged between 23.6 and 34.7 0C, relative humidity from 31.8 to 80.7% and temperature-humidity index (THI) from 21.64 to 33.52% underInshas, Sharkia Province, Egypt.
Results obtained showed that feed conversion, egg production% , egg mass )24 - 28 weeks of age(, semen ejaculate volume (ml), percentages of sperm motility and sperm-cell concentration and antibody titer against SRBC’S were improved significantly (P<0.05) ,while dead spermatozoa(%) were decreased significantly (P<0.05) for birds fed diets contained organic zinc as compared to those fed zinc oxide. Laying hens fed diets contained 105 mg Zn/Kg diet recorded best values of feed conversion, egg production(%), egg mass, fertile eggs (%), hatchability/total eggs (%) and hatchability/ fertile eggs (%) values while the lowest values were recorded with layers fed diets containing 35 mg Zn oxide /Kg diet. Inshas cocks fed 105 mg Bioplex Zn / Kg diet showed the highest sperm cell concentration and lowest in dead sperm percentages as compared with other treatment groups which, improved the positive and direct effect on the viability of sperm and consequently affect the rate of cock fertility. Heamoglobin, serum zinc and yolk zinc were higher (al most significantly) for layers fed diets contained at levels 105 or 140 Zn mg/ Kg as compared with those fed other levels of Zn at the end of experimental period. Generally, zinc from Bioplex Zn improved titer against SRBC’S better than zinc from Zn oxide.
In conclusion, diets supplemented with organic zinc at the level of 105 mg Zn/ Kg diet improved most physiological productive and reproductive traits of Inshas strain under hot summer condition in Egypt.

EFFECT OF FOOD PROCESSING ON RESIDUES OF DINICONAZOLE, ETOXAZOLE AND IMIDACLOPRID IN STRAWBERRY FRUITS
Strawberry fruits were sprayed with imidacloprid,diniconazole and etoxazole at the recommended rates of application. The effect of processing on removal of tested pesticide residues from strawberry fruits were studied.According to their half-life (t1/2) values, strawberry fruits can be safely harvested for human consumption or for processing purposes 14 ,7 and 3 days after the spraying of imidacloprid, diniconazole and etoxazole , respectively . The removal ratio of imidacloprid, diniconazole and etoxazole residues in strawberries were in the range of 9.9–30.55%, 10.0–29.52% and 15.0 – 46.67%, respectively, by washing with tap water .The average amount of imidacloprid, diniconazole and etoxazole residues in strawberry fruits, juice , syrup under cold and hot break were greatly decreased compared with those in unwashed strawberry fruits. Moreover, the amount of residues of the three tested pesticides was more greatly decreased in strawberries syrup under hot break than cold break.
Pesticide residues were concentrated into jam and increased to higher levels than strawberry juice. A change in physical and chemical properties of strawberry fruits and products was related mainly to the processing operations.

REDUCING CHILLING INJURIES OF PONKAN TANGARINE FRUITS DURING DISINFESTATION WITH COLD QUARANTINE TREATMENT BY USING SOME HEAT WATER TREATMENTS AND IMAZYLIL
Two experiments were conducted during 2009 and 2010 seasons at the Post-harvest Laboratory of Horticulture Department, Faculty of Agriculture, Zagazig University to assess the effectiveness of imazylil (IMZ) and hot water treatments (HWT) , as follow : 1- Fruits were dipped in water (20oC ) for 5min., 2- Fruits were dipped in IMZ 1000 ppm (20oC ) for 5 min., 3- Fruits were dipped in hot water (52oC) for 2 min., 4- Fruits were dipped in hot water (60oC) for 20 Sec. and 5- Fruits were dipped in hot water (70oC) for 10 Sec. as well as three cold storage periods under 2oC (as a cold quarantine disinfestation) and 90 – 95% relative humidity as follow : 10, 20 and 30 days on Ponkan tangarine fruits and shelf life period after 3 and 6 days.
Advancing storage period caused progressive increment in chilling injury (CI), fruit decay (FD), heat injury % (HI), fresh weight loss (FWL %) and acidity % of samples taken during cold storage as well as FWL %, Pulp % juice %, juice volume/kg fruits, peel firmness, acidity %, TSS %, and technological index (TI) during shelf life periods. On the contrary, increasing cold storage period decreased pulp firmness, peel firmness, TSS/acid ratio and vitamin C. In addition, peel percentage, pulp firmness, TSS/acid ratio and vitamin C depressed with increasing cold storage during after shelf life periods.
The tested hot water (HW) and fungicide (IMZ) treatments decreased CI and FD percentage of fruits during either cold storage or shelf life periods. In addition, there is no effect of tested treatments on fruit quality attributes during cold storage or during shelf life periods.

PHYTOHORMONES SCREENING OF Drosera capensis AS INSECTIVOROUS PLANTS AND ITS EXTRACT EFFECT ON in-vitro GROWTH AND DEVELOPMENT OF DATE PALM (Phoenix dactylifera cv. Bartamouda)
Carnivorous or insectivorous plants belong to several botanical families, the most important of them is Droseraceae, which includes Drosera plants. Some economic substances are extracted from Drosera. Tissue culture technique provides the best way to obtain as high and clean quantity as possible of the biomass needed to obtain these substances. This study aimed to evaluate the Drosera capensis content from phytohormones. Also studying the effect of Drosera capensis leaf and root extracts as plant growth substances on in-vitro growth of one of the most important crops that is Phoenix dactylifera cv. Bartamouda.
The amounts of phytohormones in this plant (mg 100g-1 fresh weight) were as following: Indole acetic acid in leaf was 2.055, while in case of root was 2.291. Zeatine in leaf was 1.609, while in case of root was 0.418. Other cytokinins in leaf was 18.791, while in case of root was 1.003. Gibberellic acid in leaf was 70.938, while in case of root was 86.59. Abscissic acid in leaf was 0.500, while in case of root was 0.158. Concentrations of the extract of Drosera capensis leaves and roots were applied at different ratios in in-vitro experiments of date palm cv. Bartamouda. The results revealed that Drosera capensis root extract had a significant effect on fresh weight of date palm embryogeneic callus as the best result (4.63 g) was observed with using Drosera capensis root extract at 3.0 ml L-1. Using of Drosera capensis root extract at 0.05 ml L-1 gave rise to higher number of mature embryos. The highest significant shoot number (21 shoots) of date palm was obtained with using 1.0 ml L-1 Drosera capensis leaf extract. Also the length of date palm shoots increased significantly by using the same concentration of Drosera capensis leaf extract and reached 3.3cm.
Finally, in-vitro date palm cultivation can be achieved with MS medium supplemented with Drosera capensis extract as a source of phytohormones at different micropropagation stages.

In-vitro CULTIVATION OF Drosera capensis AS AN INSECTIVOROUS PLANTS AND ITS EXTRACT EFFECT ON LARVA OF RED PALM WEEVIL
Carnivorous or insectivorous plants belong to several botanicalfamilies, the most important of them is Droseraceae, which includes Droseraplants. Insecticide substances are extracted from Drosera. Tissueculture technique provides the best way to obtain as high and clean quantityas possible of the biomass needed to obtain these substances. This studyaimed to propagate the Drosera capensis in-vitro and studying the effect ofDrosera capensis residue on larva of red palm weevil. Shoots were visibleon leaf explants, apparently forming directly on leaf surfaces without intermediatecallus.The best results of shoot number (13.8 shoots per explant) andlength (2.93 cm) were obtained at 0.05 mg L-1 BA compared with the control,BA-free media, observed 2.8 shoots per explant and 2.27 cm in length.Shoots were sub-cultured on half strength of MS medium supplementedwith four concentrations of IBA (0, 0.5, 1.0, 2.0 mg L-1) in rootingstage. MS basal medium supplemented with 1.0 mg L-1 IBA achieved thebest root formation where the root number was 47.3 per plant. The residueof Drosera capensis plants at different concentrations (0.0, 50.0, 100.500.0 mg per liter) had been given to fully developed larvae of red palmweevil (Rhynchophorus ferrugineus Oliv.) through their feeding diet. Larvaewere obtained from the field and were maintained on the stems of sugarcaneprior to mass rearing, artificial diet, which was formulated fromsucrose, molasses, potatoes and agar. The residue of Drosera capensishad toxicological effects on R. ferrugineus larvae. The lethal action ofDrosera capensis residue had appeared clearly at 500 mg L-1 where the lethalpercentage of red palm weevil larva was 65% after ten days.
