库尔勒香梨;花萼;发育;花萼脱落;花萼宿存
摘  要：
通过田间调查分析,库尔勒香梨花萼脱落高峰在盛花后12 d,多数幼果在盛花后8 d即可看出花萼脱落与否。同一花序中随序位升高,花萼脱落能力增强。萼端突起的时间是6月底。脱萼果萼端突起是因为花萼脱落时有较长的萼筒存在。人工剪萼可使多数宿萼果发育成洼顶果。花萼的脱落同果顶凹陷成正相关,花萼的宿存与果顶突起成正相关,相关系数分别是0.994和0.957。

摘  要：
After investigation and analysis in orchard,the peak of calyx dropping was found on 8 th day after full bloom.Whether calyx of the most young fruit was dropped or not often appeared at 8 days after full bloom.The ability of calyx dropping became stronger with its order place rising in the same inflorescence.Fruit end sticked up at end of June.The reason why calyx fruit end sticked up is that there was a longer calyx sepal canister on the top of fruit,when calyx dropped.Artificial cutting calyx can make most presistent calyx fruit be low-lying end one.Calyx dropping is positively correlative with the hollow of fruit top,and persistent calyx fruit had positive correlation with bulge of fruit too,and the two of correlation coefficients were 0.994 and 0.957 respectively.
