Abstract:

对中国长江中下游地区的江苏、浙江、安徽、湖北、湖南5个省的7个市(南京、无锡、扬州、杭州、合肥、武汉、长沙)的禾本科植物进行了采样调查。从以上地区的17个地点发现了大量的分蘖上长有真菌子座的鹅观草植物群落。从中分离到75株真菌菌株,并对这些菌株进行了形态学研究真菌子座圆柱状,初期白色,成熟后变黄;子囊壳梨形,高205~275μm,最大直径90~140μm;子囊柱状,(188.6~251.7)μm×(5.0~5.3)μm;子囊孢子无色透明,丝状,(183.4~250.2)μm×(1.9~2.1)μm,萌发时有隔膜,不分节;分生孢子无色透明,舟形或肾形,单个顶生,(4.9±0.6)μm×(2.8±0.7)μm;分生孢子梗长16.5~30.6μm,基部宽2.2~3.1μm,顶端变尖,为典型的Epichloё属真菌的形态结构。研究发现我国的Epichlo-ёRoegneria组合在长江中下游地区分布比较广,资源丰富,而且这些真菌的形态学特征显示,这些菌株与前人报道的有明显的差别。
