Effect of AVG Application on Berry Set of ‘Kyoho’ Grapevine

Hu Jianfang(College of Horticultural Science, CAU) He Haiyang(Urumchi Environmental Resource Development Laboratory)  
Effects of using AVG (aminoethoxyvinylglycine) on fruit set of ‘Kyoho’ grapevine have been investigated for 4 years. Flower clusters were dipped in AVG at 25, 50, 75, 100 and 300mg·L -1 about 1 to 3 weeks before anthesis. The results showed that the AVG enhanced the rate of berry set and seeded berries. The effective period of AVG was two weeks before anthesis, and suitable concentration of AVG was 100mg·L -1 . The higher effective concentrations of AVG were needed for the earlier application of AVG, and the lower effective concentrations of AVG for the latter AVG application. There were no significant differences found in soluble solid content and titratable acidity between the control and AVG treated berries, but the AVG treatment increased the berry weight. ACC content and ethylene evolution rate from florets was lower by the AVG treatment.
