乌昌地区窖藏马铃薯菌物病害调查及病原鉴定

摘要

The purpose of this paper was to investigate and define the kinds and the pathogens of fungus disease of potato during storage Urumqi and Changji areas,Xinjiang.Six kinds of fungus diseases and 10 pathogens were defined:dry rot (Fusarium sp.),Rhizoctonia canker (Rhizoctonia solani ),late blight (Phytophthora infestans ),Verticillium wilt (Verticillium dahliae ),early blight (Alternaria solani )and Skin-spot disease (Polyscytalum pustulans ).Among them,5 pathongens causing potato dry rot disease were found:Fusarium acuminaturn ,F .culmorum ,F .solan ,F .semitectum ,F .sambucinum .%对新疆乌鲁木齐和昌吉地区的窖藏马铃薯进行了菌物病害初步调查，并分离和鉴定其病原菌，经鉴定共确定马铃薯贮藏期菌物病害6种、病原菌10种：干腐病(Fusarium sp．)、黑痣病(Rhizoctonia solani )、晚疫病(Phytophthora infestans )、黄萎病(Verticillium dahliae )、早疫病(Alternaria solani )和皮斑病(Polyscytalum pus-tulans ).其中，马铃薯干腐病菌有5种：锐顶镰孢(Fusarium acuminaturn )、黄色镰孢(F ．culmorum )、茄病镰孢(F ． solani )、半裸镰孢(F ．semitectum )、接骨木镰刀菌(F ．sambucinum ).
