选择含有内生真菌的鹅观草,采集其成熟种子,经过南京的6—9月室温处理后冷藏。经过发芽、育苗以及田间栽培试验,调查并分析这些植物的长势、分蘖数、株高、茎宽、叶宽的变化,最后检测这些鹅观草植株中内生真菌的有无。结果表明:含内生真...选择含有内生真菌的鹅观草,采集其成熟种子,经过南京的6—9月室温处理后冷藏。经过发芽、育苗以及田间栽培试验,调查并分析这些植物的长势、分蘖数、株高、茎宽、叶宽的变化,最后检测这些鹅观草植株中内生真菌的有无。结果表明:含内生真菌(EI)的鹅观草植株群苗期生长比较旺盛、分蘖比较多,但在成熟期株高、茎秆直径及叶宽与不含菌植株无显著差异。从EI鹅观草植株中随机分离获得4个内生真菌菌株,其形态学特征和系统发育学特征显示,分离菌株均为Neotyphodium sinicum Wang,Ji et Kang。本研究首次证明了在田间条件下内生真菌N.sinicum能促进其宿主鹅观草的苗期生长和分蘖,揭示了禾本科植物/内生真菌共生体可作为麦类作物育种利用的可能性。展开更多
