Abstract
Grape cultivar Early Sweet is seedless and early harvested in Egyptian viticulture. However, its widespread production is limited by two main problems; small berry size and formation of shot berry. Several attempts utilize safe growth regulators alone or in combinations to improve berry characteristics. The current study aims to improve the quality and quantity of the "Early Sweet" grapes by applying GA3 and BA as well as triacontanol under Egyptian conditions. The results showed that GA3 (10ppm) Followed by either benzyl adenine at 20ppm or triacontanol at 100ppm increased cluster weight, berry size, berry weight, TSS, total sugars, leaf area and leaf mineral content. Moreover, the above treatment decreased berry acidity, electrolyte leakage and berry carotene content. In addition, the individual treatments such as GA3, BA and triacontanol enhanced the physical and chemical characteristics of "Early Sweet" grapes as compared with the control treatment.
