摘要：利用组织分离法从欧美杨2品种欧美杨107杨、中林46杨中(996块组织)分离内生真菌1252株,107杨和中林46杨分别分离出645株和607株。利用形态特征和分子生物学方法鉴定为17个属、32个分类单元,包括担子菌2个分类单元,子囊菌30个分类单元均为子囊菌。在基于ITS构建的系统进代树上、2杨树品种内生菌均形成5个稳定的分支,包括在囊菌纲2个分支,包括散囊菌纲、类壳菌纲等。2个杨树品种内生真菌优势种群包括链格孢、葡萄座腔菌、镰孢菌、间座壳菌等,其中链格孢、葡萄座腔菌是最为常见的优势种群,2品种内生菌的优势种群会随季节变化而发生变化。
In order to understand predominant species, seasonal dynamic and diversity of fungal endophytes in barks of Populus ~ euramericana cv. ＇ 74/76＇ and P. × euramericana cv. ＇ Zhonglin46＇ ,fungal endophytes were isolated from the barks by tissue isolation method, and identified by sequence analysis of the internal transcribed spacer and by morphological characteristics of microscopic observation. A total of 1 252 fungal endophytes were isolated from 996 bark tissues. The fungal endophytes were classified into 32 different fungal taxa belonging to 17 genera of Ascomycota. The predominant species included Alternaria alternata, Botryosphaeria dothidea, Fusarium spp. , Diaporthe spp. , among which A. alternata and B. dothidea were the most common predominant species in the barks. The predominant fungal endophytes in the bark tissue varied in different seasons.
