【摘要】 对河口地区主栽的不同品种香蕉分3条线路进行样本采集,对采集到的香蕉组织进行内生真菌分离、鉴定,共分离到9属494株内生真菌。鉴定结果表明,刺盘孢属(Colletotrichun sp.)、曲霉属(Aspergillus sp.)、青霉属(Penicillin sp.)为优势菌群。这3种优势菌群在东部路线、中部路线、西部路线的分离频率分别为78.37%、79.55%、76.54%;在巴西蕉,威廉斯,红研一号、红研二号中的分离频率分别为84.19%、77.32%、79.60%、71.48%。表明香蕉植株组织内内生真菌具有多样性,为进一步研究提供基础数据。更多还原

【Abstract】 The sample collection of different varieties of Banana was carried out from 3 lines, the endophytic fungi from the tissue specimens was isolated and identified. About 494 strains of endophytic fungi were obtained, they could be classified into 9 genera. Colletotrichun, Aspergillus and Penicillin were dominant fungi. The isolation frequency of these three dominat fungi in the eastern direction, central direction and western direction were 78.73%, 79.55% and 76.54%, respectively. The isolation frequency were 84.19%, 77.32%, 79.60% and 71.48% in varieties of Ba Xijiao, Weilians, Hongyan 1 and Hongyan 2.It was concluded that the endophytic fungi species of Banana plants in Hekou area had great diversity,which could provide references for the further research.更多还原
