本文研究了苹果梨果实畸变的原因，结果表明：果形偏斜与座果过多在生长期中互相挤压有关。果形严重畸变则是授粉不足或种子发育与生长不良的结果。这种变化在冬果梨的研究中也获得同样结果。对座果过多的果树可用疏花疏果的方法减少座果率。对果实畸变较重的果园则应采取增加适宜受粉树的配置和改进授粉的方法促进果树受粉和种子的形成 In this paper, the causes of apple fruit distortion were studied. The results showed that the fruit shape deflection and the excessive fruit production were related to each other during the growth period. Serious distortion of fruit shape is the result of insufficient pollination or seed development and poor growth. This change has also yielded the same result in the study of winter pear. Fruits on too many fruit trees can be thinning thinning methods to reduce fruit rate. Orchards with heavy distortion of fruit should adopt the method of increasing the configuration of pollination tree and improving pollination to promote the powder and seed formation of fruit trees
