枇杷花疫病于2007年在浙江省德清县严重发生,造成枇杷花穗枯萎和死亡.为了鉴定其病原菌,从受害枇杷花穗上分离到6个病原菌菌株.依据病原菌的形态学和培养特征,该病原菌被鉴定为灰葡萄孢菌(Botrytis cinerea) ,其有性态为富氏葡萄孢盘菌(Botryotinia fuckeliana Whetzel .) .通过核糖体DNAITS序列分析,分离菌株序列与富氏葡萄孢盘菌序列100 %同源,进一步证明侵染枇杷花穗的病原菌是灰葡萄孢菌(Botrytis cinerea) .致病性试验结果表明,B.cinerea能侵染枇杷花穗,可引起与自然寄主上相似的病害症状.
Loquat flower blight occurred seriously in Deqing County, Zhejiang Province in 2007, resulting in the wilt and death of the loquat flower.In order to identify the pathogen, six pathogens were isolated from the damaged loquat flower spores.Based on the morphological and cultural characteristics of the pathogen, The pathogen was identified as Botrytis cinerea, which had the morphological status of Botryotinia fuckeliana Whetzel .According to the ribosomal DNA ITS sequence analysis, % Homology, to further prove that the pathogen infected loquat flower spores Botrytis cinerea (Botrytis cinerea) .The pathogenicity test results show that B.cinerea can infect loquat spikes can cause similar to the natural host disease symptoms .
