本文对刺槐和沼泽桉叶片上胶孢炭疽病菌的一类菌株(Colletotrichum gloeosporioides Penz.)的生物学特性、形态及分类等问题进行了探讨。该类菌株通常以无性世代出现。在分生孢子堆上形成纺锤形孢子;在菌丝上产生椭圆至卵形孢子,具有二型现象。在马铃薯、洋菜培养基上培养时,菌落呈红色。若进行人工接种,则于茶叶片上产生子囊世代。按其形态、特性,该类菌株应为Glomerella cingulata (Stonem.)S.et S.的红色型。
In this paper, we discussed the biological characteristics, morphology and classification of a strain of Colletotrichum gloeosporioides Penz. Such strains usually appear in clonal generation. In conidial heap formation of sporozoite spores; in the hyphae oval to oval spores, with two type phenomenon. Colonies were red when cultured on potato and agar medium. If artificial inoculation, the generation of ascus on the tea leaves generation. According to their morphology and characteristics, these strains should be the red type of Glomerella cingulata (Stonem.) S. et S.
