Abstract
Grapes grown in high temperature areas encounter serious problems regarding various yield quality characteristic. The most important quality attributes of table grapesplanted in these areas are berry coloring and chemical constitutes. Therefore, improving berry quality are essential aims for growers to fulfill the requirements of the market and the consumers. This study was carried out during 2016/2017 seasons to investigate the effect of foliage sprayed methyl jasmonate at a rate of 5 and 10 ppm and humic acid at a rate of 5 and 10 ppm as well as amino acids (glutathione at a rate of 50 and 100 ppm, tryptophan at a rate of 50 and 100 ppm) and potassium at a rate of 1 and 3% on berry development of Vitis viniferacvs. Flame Seedless, Ruby Seedless and Red Roomy growing on the experimental orchard of Faculty of Agriculture, Assiut University. Result of the present work suggested that spraying clusters of Flame Seedless, Ruby Seedless and Red Roomy grape cultivars with the higher concentration of MJ, HA or K significantly enhanced berry sensory attributes and antioxidants content with no negative effect on the yield. Accordingly, from the majority of the present result of the current work it can be recommended that, for economical purposes, to spray either HA at 10 ppm or K at 3%. They gave the best berry quality with reasonable yield.
