摘要(Abstract)：
从西南四省区(云、贵、川、藏)的土壤和其它样品中分离木霉301株,鉴定出9个木霉集合种(species aggregates) :哈茨木霉(Trichoderma harzianum Rifai),拟康氏木霉(T.pseudokoningii Rifai),长枝木霉(T.longibrachiatum Rifai),深绿木霉(T.atrovirideBissett),桔绿木霉(T.citrinoviride Bissett),绿色木霉(T.viride Pers.ex S.F.Gray),钩状木霉(T.hamatum(Bon)Bain),康氏木霉(T.koningii Oud.)以及黄绿木霉(T.aureoviride Rifai)。从各个样点收集的42种不同作物和其它植被土样中都分离到木霉;土样pH值为4—8.5,海拔300—5400m。以哈茨木霉和拟康氏木霉出现频率最高,分别为28.5%和21.1%,似为西南地区木霉优势种群,而绿色木霉、钩状木霉和深绿木霉很少分离到。这样的种群结构可能与西南地区气候和采样季节有关。
