Abstract
In order to research the relevant factors and correlation of rough fruit formation on pears ,taking Kor-la fragrant pear as materials ,some relevant factors of rough fruit formation were surveyed such as some envi-ronmental factors and tree canopy factors ,ion content of rough fruit and normal fruit were compared and rele-vant impact factors of rough fruit formation were explored .The results showed that through the investigations of rough fruit there were an equal on rough fruit percentage among canopy lumen ,canopy exocoel injured bran-ches and unhurt branches ,and the rough fruit percentage of short branch ,big fruit ,all inflorescence was higher than 95% .There was no significant difference on the content of K + ,Mg2+ and Na+ in rough pear adjacent leaves compared with normal pear adjacent leaves ,Fe2+ and Ca2+ in rough pear adjacent leaves was significantly lower than normal pear adjacent leaves ,Zn2+ in rough pear adjacent leaves was significantly higher than normal pear adjacent leaves .There was no significant difference on the content of K + ,Mg2+ ,Ca2+ and Zn2+ in rough pears compared with normal pears ,Na+ in rough pear was significantly lower than normal pear ,Fe2+ in calyx part of rough pear was no significant difference compared with normal pear ,but Fe2+ in rough pear was signifi-cantly lower than normal pear .关键词
