槲蕨根际真菌与内生真菌的多样性及相关性分析

Diversity and correlation of endophytic fungi and rhizosphere fungi isolated from Drynaria roosii

对槲蕨(Drynaria roosii)的根际真菌和内生真菌进行分离,共获得46株根际真菌,分属2亚门5目6科9属,青霉属、曲霉属、木霉属、镰刀菌属为槲蕨根际真菌优势属;50株内生真菌分属于1亚门4目5科12属,青霉属、曲霉属、木霉属、镰刀菌属为槲蕨内生真菌优势属。槲蕨植物内生真菌及其根际真菌具有丰富的多样性,也具有一定的相关性。

The rhizosphere fungi and the endophytic fungi were isolated from Drynaria roosi.The results showed that there were 46 strains of rhizosphere fungi belonging to 9 genera,6 families,5 orders,2 subdivision,Penicillium,Aspergillus,Trichoderma,Fusarlum were the dominant genus of endophytic fungi;50 strains of endophytic fungi belonging to 12 genera,5 families,4 orders,1 subdivision,Penicillium,Aspergillus,Trichoderma,Fusarlum were the dominant genus of rhizosphere fungi.There were abundant diversity and certain correlation between endophytic fungi and rhizosphere fungi of Drynaria roosii.
