EFFECT OF SOME MANGO ROOTSTOCKS ON THE PERFORMANCE OF KEITT,NAOMI AND HAYDI MANGO VARIETIES
This investigation was carried out during the two consecutive seasons (2019 and 2020) respectively on mango trees (Mangifera indica L.) cvs. "Keitt,Naomi and Haydi " grown in a private orchard at El Salhia region , Sharkia Governorate , Egypt. In a sandy soil and irrigated with drip irrigation system .Trees were 7-year-old ,planted at 2*4 m space to evaluate the effect of some mango rootstocks (Balady and succary ) on vegetative growth ,flowering , fruiting ,yield and fruit quality of these mango varieties "Keitt,Naomi and Haydi " There is a relationship between the rootstocks of mango trees and their scions including vegetative, flowering characters and also yield in quality and quantity .AS for vegetative characters ,the thickness of rootstocks and scions zones, which showed the differences in Keitt ,Naomi and Haydi varieties .That gave more thick in Keitt than the other varieties .Also, showed that Balaby rootstocks of came more thick than Succary one in this study .The leaf area was affected in this study in two seasons ,however leaf area of Keitt and Naomi varieties gave ahigh measureable than Haydi leaf area in both season of study . Average number of sprouts in spring time , summer time and also autumn time .The number of Haydi,Naomi and late Keitt in descending order .The number of sprouts in the time of spring followed by summer sprouts.The floral characters was affected by rootstocks markedly .however, panicle length showed that more length with the rootstock of Balady than Succary with variety of Keitt and Naomi while the Succary rootstock gave more length in variety of Haydi than the other Keitt and Naomi in the two seasons .As for branches number/panicle in Keitt variety on Balady and Succary rootstocks had shown significantly differences. The Naomi and Haydi appeared a variance in large number in Succary rootstock than Balady. Fruit physical properties was also affected significantly by rootstocks as fruit length ,width and shape index .In addition, fruit weight and pulp weight showed that Succary rootstock gave more fruit weight and pulp weight than Balady rootstock .Also fruit chemical properties as TSS, total acidity percentage ,TSS/acid ratio, carotene (mg/100gm) and vitamin C (mg/100ml) showed a significantly differences in both seasons of study. Conclusively, from these results of this research , the rootstock of Succary gave more yield /tree as the other rootstock of Balady one in the two seasons of study with trees were-7-year old.
