| 摘 要： | 云南省西双版纳地区白菜、薄荷、莴苣叶腐病频繁发生，从有叶腐症状的病害组织中分离到立枯丝核菌（Rhizoctonia solani）菌株。根据培养性状、菌丝直径、细胞核数目、融合群反应、5.8 s rDNA片段序列分析及致病性测定，结果表明引起白菜、薄荷、莴苣叶腐病的病原菌为立枯丝核菌AG-1 IB菌丝融合群。

| Abstract: | Leaf rot was frequently observed in Chinese cabbage,mint and lettuce in Xishuangbanna district of Yunnnan Province,China.Rhizoctonia solani isolates were collected from the diseased leaves and were identified to belong to anastomosis group AG-1 IB based on cultural characteristics,mycelial diameters,nuclear numbers,anastomosis reaction,analysis of the ITS-5.8s rDNA region and the pathogenicity test. |
