摘要：

为了防治大血藤炭疽病，通过组织分离法从病果中分离得到病原菌，并对病原菌进行培养、孢子大小测定和鉴定。显微镜镜检的病原菌特征表明，引起大血藤炭疽病的是炭疽菌(Colletotrichum sp.)，测微尺测量大血藤炭疽菌的孢子大小为5.2~6.5 μm×13.0~33.8 μm，结合寄主和病原特征，表明引起大血藤炭疽病的病原菌为胶孢炭疽菌(Colletotrichum gloeosporioides)。胶孢炭疽菌(Colletotrichum gloeosporioides)引起贵州省黔东南州的大血藤炭疽病，可以通过农业防治和药剂防治来减少病害的危害。

Abstract:

The aim was to prevent anthracnose of Sargentodoxa cuneata in Qian Dongnan State of Guizhou Province. The pathogen was obtained by tissue isolation, and identified by separation, spores size determination and cultivation in this experiment. The microscopic examination method showed that the disease was caused by Colletotrichum sp., and the spores were 5.2-6.5 μm×13.0-33.8 μm through size determination. Based on host and pathogenic feature, the pathogen was Colletotrichum gloeosporioides. The disease of Sargentodoxa cuneata was caused by Colletotrichum gloeosporioides. in Qian Dongnan State of Guizhou Province, and the disease could be reduced through agricultural measures and chemical control.
