Isolation and Identification of Pathogenic Fungi Causing Fruit Rot of Kiwifruit in Fengxin County
In order to ascertain the fungi which cause rot of kiwifruit fruit, fungi were isolated from a large number of rotten fruit, and the isolated fungi were molecularly identified and tested for their pathogenesis. The results showed that six kinds of fungi were responsible for fruit rot of kiwifruit in Fengxin Connty. They are Botryosphaeria dothidea, Botryotinia fuckeliana, Pestalotiopsis sp. , Fusarium proliferalum, Phomopsis sp. , and Alternaria sp. Among them, Botryosphaeria dothidea is the dominant pathogen having 83.0% of isolation rate, and next is Phomopsis sp. having 8. 9% of isolation rate. The results also showed that Botryosphaeria dothidea is able to penetrate fruit of kiwifruit by direct penetration of cell walls or through wounds, while the other five kinds of fungi penetrate fruit of kiwifruit only through wounds. The results way have important significance for control and further research of fruit rot of kiwifruit in Fengxin County.
