博落回内生真菌种类与分布

Endophyte Species Composition and Distribution of Macleaya

研究药用植物博落回内生真菌的种类组成、数量及分布规律.从博落回根、茎、叶中分离得到91株内生真菌,分属5个科11个属,青霉属(Penicillium)、曲霉属(A spergillus)为优势菌株,分离率分别为1.06%、0.91%,其次为刺盘孢菌(Colletotrichum),分离率为0.83%.结果表明:博落回器官不同,其内生真菌群落结构及存在的数量有明显差异,其中叶器官内生真菌种类最多;季节对博落回内生真菌的种类及分布也有重要影响.

The endophyte species composition, number and distribution of the medicinal plants Macleaya were investigated. 91 strains of endophytic fungi was isolated from cordata root, stem and leaves. They are belonging to 5 families, 11 genera including the dominant strain： PeniciUium Aspergillus, separation rates were 1.06%, 0.91%, Followed by Colletotrichum separation was 0.83%. The results show that endophyte community structure and the existing number of significant differences in the different organs Macleaya, which leaves have the largest organ of endophytie fungi ; season also have important implications to Maeleaya species of endophytic fungi and distribution.
