GA_(4+7)的浓度、处理时期与次数及处理间隔时间多个因子的组合确定它们对于防止金冠苹果产生果锈的效应。盛花后8天或15天处理幼果,减少果锈的效果最佳。尽管在某些情况下高浓度处理能增进对果锈的控制,但适宜的处理时期与处理次数比用高浓度赤霉素防控果锈的效果更好。果梗长度和果形指数较大的果实果锈减少。在果实长度及果梗长度与果锈之间观察到了显著的相关性。GA_(4+7)处理还影响到座果,在许多情况下导致单性结实。
The combination of GA_ (4 + 7) concentration, duration and number of treatments, and treatment interval time determine their effect on preventing fruit rusts in Golden Delicious apples. 8 days or 15 days after flowering Young fruit treatment, to reduce the best rust effect. Although high-concentration treatment can enhance the control of rust on some occasions, the proper treatment period and treatment times are better than the prevention and control of rust-rust with high concentration of gibberellin. Fruit peduncle length and fruit shape index fruit rust reduced. Significant correlations were observed between fruit length and fruit stem length and fruit rust. GA_ (4 + 7) treatment also affected the fruit, which in many cases led to unisexuality.
