摘　　要：对翠冠梨果实种子发育与果形偏斜情况进行的观测,结果表明,翠冠梨果实中种子总数、饱满种子数与偏斜度、斜果率关系密切,均呈负相关,即随着果实中种子总数、饱满种子数的增加,果实的偏斜度、斜果率趋小,当种子分布极度不平衡时则极易发生畸形果。但部分果实虽种子数量较多且分布也较平衡,仍有相当数量偏斜果和少量畸形果的发生,说明梨果实偏斜并非都是因种子发育不良与分布不均所致。In our study, seeds development and skewness and deviation status of pear cv. ‘Cuiguan＇ was observed. The results showed that total seed number and full seed number showed all negative correlation with degree of skewness and deviation rate, meaning that the degree of skewness and deviation rate decreased with the increase of total seed number and full seed number. Moreover, it produced abnormal fruits very easily when the seed distribution was imbalanced extremely. However, there were a considerable amount of deviation fruits and a small amount of abnormal fruits, even if some fruits showed larger seed number with more balanced distribution. It was proved that skewness and deviation of fruit shape in pear could not result from poor seed development and unbalanced seed distribution.
