| 摘 要： | 采集感染炭疽病的漆树病叶，组织分离得病原菌纯培养，根据病原菌的形态、培养特征、致病性和寄主范围将其鉴定为胶孢炭疽Colletotrichum gloeosporioides (Penz.) Sacc.。进一步研究其生物学特性发现，漆树炭疽菌菌丝生长与时间呈直线相关，菌丝在10~35 ℃范围内均能生长，生长最适温度为25~28 ℃，分生孢子致死温度为48 ℃，分生孢子在相对湿度达到90 %时才能萌发，连续光照可以促进菌丝生长量和产孢量的增加，菌丝在pH 3~12 范围内均能生长，生长最适pH为6.0。漆树炭疽菌对多种碳、氮源都能利用，以葡萄糖、果糖为碳源以及以天门冬酰胺、丙氨酸为氮源时，其菌丝生长最佳。

| Abstract: | To ascertain the species of Lacquer anthracnose pathogen and its growth characteristics,Lacquer leaves infected with anthracnose disease were collected,and pure culture of the pathogen was acquired by tissue isolation method.The pathogen is determined to be Colletotrichum gloeosporioides （Penz.） Sacc.by its morphologic characters,cultural characteristics,pathogenicity and host range.Further research work on its biological characteristics was conducted.It was found that mycelial growth of Lacquer anthracnose pathogen had a linear correlation with the cultural time.The temperature range of the mycelial growth was 10～35℃,and the optimum temperature was 25～28℃.The lethal temperature of conidia was 48℃.The conidia cannot germinate until relative humidity reached 90%.Continuous light may promote the increasing of yield and sporulation of mycelia.The mycelia can grow at the range of pH 3～12 and the optimum growth pH was 6.0.The Lacquer anthracnose pathogen can utilize many kinds of carbon and nitrogen source.The mycelia will grow better if glucose,fruitose was used as the carbon sources and asparamide,alanine was used as the nitrogen sources. |
