摘要: Abstract Propagules of Trichoderma generally formed less than 3 per cent the total fungal propagules in a variety forest soils southeastern U.S. and Washington State. The largest populations were found F H organic horizons floor or under conditions excessive moisture. T. viride Pers. ex S.F. Gray polysporum (Link Pers.) Rifai largely restricted to cool temperate regions; whereas, harzianum was characteristic warm climates. koningii Oud. hamatum (Bon.) Bain, most widely distributed species aggregates all climatic regions investigated. Under moisture, strains pseudokoningii dominant forms.
