芦苇内生真菌的多样性分析
Diversity Analysis of Endophytic Fungi in Reed
摘要
Abstract
In this study,the endophytic fungi in the root,stem and leaf tissue of Phragmites australis were iso-lated and purified by dilution plate method.The morphological identification of these endophytic fungi was also tested.194 strains were obtained and these strains were belonging to genus of Trichoderma,Aspergillus,Alter-naria,Penicillium,Mucor,Fusarium,and Paecilomyces.Among these genus,Fusarium,Penicillium and Alter-naria were the dominant genus,and the abundance of Fusarium,Penicillium and Alternaria was 46.39%, 26.29% and 46.39%,respectively.There are endophytic fungi in different organs of the reed,and 92 in the root,84 in the stem and 18 in the leaves.The dominant genus of root was Fusarium and Alternaria.The domi-nant genus of stem and leaf tissue was Penicillium and Fusarium,respectively.The diversity index of endophyt-ic fungi in root,stem and leaf was 2.178,1 .272 and 1 .019,respectively.The species diversity and richness index,from the big to the small,were the root >stem >leaf,and the evenness index was the leaf >stem >root.关键词
