摘要
2004-2005年,先后从呼和浩特地区及达拉特旗、四子王旗、萨拉齐采集健康杨树Populusspp.的叶、枝(包括枝皮和木质部)和干皮,从中分离获得内生真菌351株(其中23株未产生孢子),经显微形态观察分类鉴定为7目8科29属。结果表明:杨树不同部位内生真菌在数量、种群分布和优势种群方面都存在着一定的差异;不同年龄段杨树内生真菌的种类和数量发生规律性变化;不同地理分布区杨树内生真菌的数量和种群组成存在差异,但又呈现一定的规律性。
In a survey of endophytes associated with Populus spp. in Inner Mongolia from 2004 to 2005, healthy leaves, branches （including integuments and xylem） and stems were collected from Huhhot City, Dalate County, Siziwang County, and Salaqi Town. Based on morphological characteristics, 351 strains of endophytes were isolated and classified into 7 orders, 8 familes, and 29 genera. The results showed that endophytes varied in quantity, population distribution, and dominance in different tissues, regular changes showed in species and quantity for different age phases, and varied in quantity and population composition in Populus spp. of different areas.
