The effects of trunk choking, girdling and GA3 applications on the yield and quality of Gemlik olive variety

In this study, the effects of trunk choking, girdling and GA3 (75ppm and 100ppm) applications on fruit yield and quality were studied on Gemlik olive variety. The maximum number of flowers in plants with only effects of trunk Choking treatment; the maximum number of fruits and the highest rate of fruit set were observed in the plants where only effects of girdling was applied. The fruits with the highest width and length were obtained from 100ppm GA3 + Girdling applied plants and 75ppm GA3 + Girdling applied plants. Plants treated with 100ppm GA3 + Girdling gave superior results compared to other applications in terms of fruit weight, fruit flesh weight, ratio of fruit flesh to seed weight and yield. As a result of the study, the number of flowers, number of fruits, fruit set ratio, aspect values of fruits, fruit weight, yield per tree were found to be superior to control plants in all applications.
