镰刀菌(Fusarium spp.)是真菌的一个重要属,分布极为广泛,是多种重要植物的病原菌。其中,由致病性尖孢镰刀菌(Fusarium oxysporum)侵染引起的植物枯萎病是一种世界性的土传真菌病害。病菌从植物根部侵入,扩展进入维管束,造成植株枯死,在植株的全生育期均可发生,给生产带来了巨大的损失。国内外已报道的被严重为害的作物有棉花、甘蔗、香蕉、番茄、黄瓜、哈密瓜、西瓜、大豆、豇豆等。 |

In order to clarify the current Fusarium species and the dominant species causing tomato Fusarium wilt in Tongshan,Qintong and Shuyang. 12 soil samples were collected from tomato rhizosphere and the pathogens were isolated. Fusarium species were identified on the basis of morphological characteristics and ITS sequences,and their pathogenicity was also tested. Three Fusarium species,namely F. oxysporum,F. solani and F. verticillioides,were classified with the numbers of 111,32 and 7,respectively. The result of analysis of the Fusarium species distribution in different regions indicated that Fusarium oxysporum was the dominant species in Tongshan,Qintong and Shuyang with frequencies of 66%,72% and 84%,respectively. |
