波斯婆婆纳生防菌株QZ-97a的分离鉴定与致病性研究

Studies on the isolation,identification and pathogenicity of a strain QZ-97a as a biological agent for Veronica persica

从波斯婆婆纳罹病植株上经单孢分离采得一菌株QZ 97a ,经鉴定为胶孢炭疽菌 (ColletotrichumgloeosporioidesPenz .)。该菌株在实验室及温室条件下对波斯婆婆纳具有致病性 ,而对波斯婆婆纳所危害的小麦、油菜、大豆、棉花和玉米等作物十分安全 ,故炭疽菌QZ

A fungus strain QZ?97a collected from the infested plants of Veronica persica through individual spore isolation was identified as Colletotrichum gloeosporioides Penz .The strain caused obvious pathogenesis to Veronica persica under conditions of laboratories and green houses,whereas kept perfect security to such crops as wheat,rape,soybean,cotton,and corn which was generally damaged by Veronica persica. Therefore,the fungus strain QZ?97a may be with the potential of being exploited as a mycoherbicide.
