Abstract

Effects of single application of gibberellin (GA 100, 200 and 400 ppm) supplemented with streptomycin (SM 200 ppm) and forchlorfenuron (CPPU 5 ppm) at anthesis on seedlessness of 'Muscat Bailey A' grape berries were investigated. GA alone gave less than 70% seedlessness, whereas GA supplemented SM and CPPU gave it up to 90%. CPPU increased the percentage of berry set. Application of GA 400 ppm + SM 200 ppm + CPPU 5 ppm seemed to reduce berry size.
