Isolation and Identification of Pathogenic Fungi Causing Post-harvest Stem-end Rot of'Jinshi No.4'Kiwifruit
Naturally diseased fruit of'Jinshi No.4'kiwifruit were used as test material.The fungi were isolated from a large number of rotten samples,and were identified through their morphologic characteristics and molecular analysis.Koch's postulate was performed to confirm the identification. The fungi which cause post-harvest stem-end rot of yellow-flesh kiwifruit was identified,in order to provide reference for the research on the prevention and control of post-harvest rot disease of yellow-flesh kiwifruit.The results showed that eight different fungi were causable for stem-end rot of kiwifruit.They were Phomopsis sp.,Diaporthe cotoneastri,Pestalotiopsis microspora,Botrytis cinerea,Neofusicoccum parvum,Alternaria sp.,Fusarium sp.and Botryosphaeria dothidea.
