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.
