苹果、梨裂果的主要原因是水份供应不匀或天气干湿变化大形成的。果实在迅速膨大期和着色期,如果灌水过多。特别是久旱灌水,果实通过根系和果皮吸收大量水分,造成果肉细胞迅速膨大,而果皮细胞生长较慢,产生异常的膨压,超过了果皮和果肉组织细胞壁所承受的最大张力,而发生裂果。

Apple, pear split fruit is the main reason for the uneven supply of water or the formation of large wet and dry weather changes. Fruit is rapidly expanding and coloring period, if the irrigation is too much. In particular, drought irrigation, the fruit through the roots and peel to absorb large amounts of water, resulting in the rapid expansion of pulp cells, while the slow growth of pericarp cells, resulting in abnormal turgor, exceeding the pericarp and pulp cell wall to withstand the maximum tension, and the occurrence of split fruit .
