Abstract:
Taking Vitis vinifera L.‘Moldova’ as material，the effects of different concentrations of GA3 and gibberellin acid treatment on berry quality and sugar metabolism during the grape berries development were studied，in order to improve the fruit quality of table grape.The results showed that sprayed GA3 and gibberellic acid regulated berry development，invertase and Ca2+-ATPase activity.Activities of cell wall invertase and neutral invertase of grape berry significantly increased during early berry development by treated with 200 mg/L gibberellic acid，during the late berry development，acid invertase and Ca2+-ATPase activity significantly increased，average fruit weight and total soluble content were significantly improved too.So，spraying appropriate gibberellic acid could regulate sugar metabolism in berry，in the end，it could significantly improve the table grape berry quality.
