摘要:
为阐明荒漠植物蒙古沙冬青(Ammopiptanthus mongolicus)根围深色有隔内生真菌定殖的形态特征随海拔变化,2013年6月,选取内蒙古乌拉特后旗、磴口、阿拉善左旗,宁夏中卫市沙坡头等西北荒漠地区4个不同海拔梯度样地,分别从0~10、10~20、20~30、30~40、40~50 cm 5 个土层采集蒙古沙冬青根和土壤样品,系统研究了不同海拔深色有隔内生真菌定殖空间变化规律。结果发现,深色有隔内生真菌菌丝和微菌核在所选样地沙冬青根系组织普遍定殖,产生多种典型的结构;并随海拔从低到高,定殖形态出现规律性变化,即菌丝变粗,颜色逐渐变深,横隔膜缩短。微菌核由分散颗粒状聚集成簇、成团,并出现迷宫状,颜色也显现不同变化规律,且菌丝定殖率、微菌核和总定殖率逐渐增大。
