众所周知,根颈和根腐烂病是引起豆科牧草植株衰败和减产的一个很重要因素。不少的研究指出,从发病的苜蓿根系中通常分离出的多种镰刀菌,包括茄镰孢(F.So-lani),尖镰孢(F.oxysporum)和渐尖镰孢(F.acuminatum)是经常由苜蓿根中分离出来的种。
It is well-known that root neck and root rot are a very important factor contributing to the decline and yield reduction of leguminous plants. Numerous studies have indicated that a wide range of Fusarium species commonly isolated from diseased alfalfa roots, including F. so-lani, F. oxysporum and F. acuminatum ) Is a species that is often isolated from the root of alfalfa.
