以7种果树寄主离体枝条为试材,采用菌丝块接种法,测定了蓝莓枝枯病菌(Botryosphaeria dothidea)的寄主范围,将蓝莓枝枯病菌(B.dothidea)和苹果轮纹病菌(B.dothidea)分别在苹果枝条、果实以及蓝莓枝条上进行交互接种试验。结果表明,蓝莓枝枯病菌还可以侵染桃、李、樱桃、葡萄、苹果、梨等6种果树寄主,来源于我国辽宁地区的蓝莓枝枯病菌与苹果轮纹病菌可以交互侵染。
The detached shoots from seven kinds of fruit trees were used as test materials, and the mycelial inoculation method was used to determine the host range of Botryosphaeria dothidea. The contents of B.dothidea and B .dothidea) were tested on apple shoots, fruits and blueberry shoots respectively. The results showed that the blueberry blight could infect the host of six kinds of fruit trees such as peach, plum, cherry, grape, apple and pear, and the blueberry blight germ from Liaoning province in China could cross infection with the apple germ.
