对采自我国6省18市(县)的蔬菜根茎样本进行了组织分离和形态学鉴定,共鉴定出镰孢菌10个种。其中尖镰孢(Fusarium oxysporum)为优势菌,占镰孢菌总量的73.42%,其他种类的镰孢菌为锐顶镰孢(F. acuminatum)、弯角镰孢(F. camptoceras)、蓝色镰孢(F. coeruleum)、木贼镰孢(F. equiseti)、砖红镰孢(F. lateri-tium)、芬芳镰孢(F. redolens)、半裸镰孢(F. semitectum)、腐皮镰孢(F. solani)和拟轮枝镰孢(F. verticillioides)。初步明确了我国部分地区蔬菜根茎上的镰孢菌种类及优势种群,为我国蔬菜的镰孢菌病害防治提供理论基础。
Ten rootstocks of vegetables were collected from 18 provinces (counties) in 6 provinces of China, and 10 species of Fusarium were identified. Among them, Fusarium oxysporum was the predominant species, accounting for 73.42% of the total Fusarium species. Other species of Fusarium were F. acuminatum, F. camptoceras, F. coeruleum, F. equiseti, F. lateri-tium, F. redolens, F. semitectum, F. solani and F. verticillioides. The species and the dominant species of Fusarium in vegetable rhizomes in some parts of China were initially identified, providing a theoretical basis for the control of Fusarium diseases in vegetables in China.
