- 摘要:
- 从陕西不同地区采集蔷薇科、豆科、茄科等植物上具有炭疽病病症的标样85份，共分离得到炭疽菌菌株41株，选取21株菌株构建ITS的系统发育树，结果显示，21个果园周边寄主的炭疽病病原菌可初步分为8个类群，选取其中5株代表性菌株进行多基因系统发育树的构建，结果表明胶孢炭疽菌和果生炭疽菌的菌株除可侵染苹果外，还可侵染猕猴桃、辣椒、梨等寄主。对其中6个分类单元的10株菌株在苹果上进行致病性测定，结果显示所有菌株有伤接种均可发病；而归属为尖孢炭疽菌、猪毛菜炭疽菌和西蒙德炭疽菌的菌株无伤接种不能发病，证明它们对苹果没有致病性；而分别归属于果生炭疽菌、胶孢炭疽菌和松针炭疽菌的菌株无伤接种都可以发病，并表现出典型的苹果炭疽病症状，说明它们对苹果均为初侵染源，具有致病性，进一步证明果园周边梨、辣椒、猕猴桃等寄主可以作为苹果炭疽病潜在的初侵染来源，为炭疽病的有效防治提供了理论基础。
