Abstract


A field study was carried out at the Horticulture Research Farm of El-Baramon, Dakahlia, governorate,Egypt aimed to study the effects of salicylic acic (SA) and ascorbic acid (AsA) on mango trees cv Fagri kalan. Leaf area and its mineral contents as growth parameter, yield and its were evaluated. Data indicated that spraying treatments increased productivity of mango trees and enhanced their fruit quality,  in the two seasons Salicylic acid and AsA, when applied alone, produced low productivity of Fagri kalan mango compared to their combination. Spraying with 2MmSA+1Mm AsA gave the best values in this respect. Moreover, spraying with this treatment gave the highest values of TSS and total sugars in the fruits content and lowest value in acidity comparing with other interactions treatments used in both seasons. Further investigation are need to study the effects of AsA and SA on natural defiance system on some biotic and abiotic stress condition and to trace the involvement of metabolic processes in resistance to many disorder in mango.
