在苹果的花萼内或在花托表面。用微量 GA_(4+7)加 BA 混合液处理,使果形指数提高最大。花器周围或短枝叶上的 GA_(4+7)+BA 不会向花托转移。用25～600ppm 处理(每朵花0.625～15微克GA_(4+7+BA),既不影响座果,也可增加单果重。果形指数的提高,是由于果实纵径增加和横径减少的结果。果实横径的减少与重量的减轻,归因于果实种子数的减少。
Within the apple calyx or on the receptacle surface. GA (4 +7) with a small amount of BA mixture, the fruit shape index increased the maximum. GA_ (4 + 7) + BA around the flower or short branch leaves will not transfer to the torus. Treatment with 25-600 ppm (0.625-15 μg GA 4 + 7 + BA per flower) did not affect fruit set, but also increased fruit weight.The fruit shape index was increased due to the increase of fruit length and diameter The reduction of fruit diameter and weight was attributed to the reduction of fruit seed number.
