于花期进行果台副梢摘心使安梨(Pyrus ussriensis Maxim)花朵座果率提高116.2～413.3％,花序座果率提高114.9—379.6%。处理时间越早(初花到末花),效果越显著;摘心程度越重,座果率越高。果台副梢摘心的同时疏除部分花朵,使效果有所增加。果台副梢摘心处理的果实中种子数量和成熟种子数量减少,但不能形成无籽果实。

During the flowering stage, the fruit pericarp of Pyrus ussriensis Maxim increased by 116.2% to 413.3% and the inflorescence fruit rate increased by 114.9% -379.6%. The earlier the treatment time (beginning to end flowers), the effect is more significant; the more intense the degree of pinching, the higher the rate of fruit set. Fruit assassin at the same time pinching part of the flowers, so that the effect has increased. The number of seeds and the mature seeds in the fruits of the pericarp topping treatment decreased, but no seedless fruits could be formed.
