摘　　要：The sporulation conditions of Cercospora capsici were tested with physical and chemical methods.Conventional and particular media,ultraviolet radiation and different treatments on mycelia suspension were applied and studied.It was found that C.capsici could produce conidia in the media of corn leaf powder agar and pepper leaf powder agar.The numbers of conidia produced in the two kinds of botanical media were 24 000 and 35 000 spores/mL,respectively.Compared with those isolated from the leaves,the conidia produced in the botanical media were more slender and pointed in morphology.The sporulation conditions of Cercospora capsici were tested with physical and chemical methods.Conventional and particular media,ultraviolet radiation and different treatments on mycelia suspension were applied and studied.It was found that C.capsici could produce conidia in the media of corn leaf powder agar and pepper leaf powder agar.The numbers of conidia produced in the two kinds of botanical media were 24 000 and 35 000 spores/mL,respectively.Compared with those isolated from the leaves,the conidia produced in the botanical media were more slender and pointed in morphology.
