中国木霉属内生真菌一个新记录种 Trichoderma chlorosporum

1 INTRODUCTION Typically,Trichoderma spp.are free-living fungi most frequently isolated from soils and have been extensively studied due to their remarkable biocontrol and plant-growth promoting capacity.There is increasing evidence that sometimes they display flexible lifestyle and penetrate epidermis of roots and act as opportunistic,avirulent plant symbiont(Harman et al.2004).Recently,a Trichoderma species living as endophyte,Trichoderma taxi C.L.Zhang et al.(2007),has been recognized.
