摘要
为了探明鱼腥草中内生菌的分布规律,便于有目的筛选有益菌株,对湖南农业大学附近一农户栽培鱼腥草不同器官中内生菌的数量分布及细菌的一般特性进行了研究。结果表明,鱼腥草根、茎、叶中都存在大量内生菌,总的数量趋势是根大于茎,茎大于叶。同时各器官中细菌数大于放线菌数,放线菌数大于真菌数(叶中真菌数大于放线菌数)。各器官中的内生细菌以革兰氏阴性芽胞杆菌为主,其中茎表现最为明显。
In order to ascertain the distribution rule of the endophytes in Houttuynia cordate and to supply some useful advice for selecting excellent strains,the studies on the endophytes＇ number distribution and the bacteria＇s general characteristics in the different organs of Houttuynia cordate,which were cultured by a farmer near Hnnan Agricultural University,were conducted. The result showed that：there were a lot of endophytes in Houttuynia cordate＇s roots,stems and leaves. Generally speaking,the number of endophytes in the roots were more than sterns,and the leaves were the least. The number of bacteria in each organ were more than the actinomycetes,and fungi were the least （fungi in leaves were more than actinomyctes）. The Gram-negative bacillus were the main endophytic bacteria in the organs,especially in the stems.
