橡胶树炭疽病是我国广东、广西、云南和福建四省(区)植胶垦区普遍发生的一种叶片病害。我们通过对来自不同地区、不同植物部位、不同叶龄和病斑类型的33号炭疽病标本,进行了自然形态鉴定,野生型单孢纯培养特性的观察和不同寄主致病性的测定。根据Von Arx分类系统,确定我国植胶垦区橡胶树炭疽病菌种名为Colleotrichum gloeosporioides Penz。
Rubber tree anthracnose is a kind of leaf disease commonly occurred in the reclaimed rubber planting areas in four provinces (autonomous regions) of Guangdong, Guangxi, Yunnan and Fujian in China. We identified the natural morphological characteristics of 33 anthracnose specimens from different regions, different plant parts, different leaf age and lesion types, observed the pure culture characteristics of wild-type single-spore and measured the pathogenicity of different hosts. According to the Von Arx classification system, the species of Colletotrichum gloeosporioides Penz in rubber plantation in China was identified.
