The endophytic fungi from root, main stem, branch and leaf of Scrophularia ningpoensis were isolated and identified from Wulong and Chongqing, and the population diversity analysis and phylogenetic analysis were followed. The result indicated that, as to population diversity index, S. ningpoensis from Wulong： leaf>main stem=branch>root, branch from Chongqing>branch from Wulong. Fifty-eight endophytic fungi were obtained, most of which were the pathogens of the plant. Colletotrichum was the prevailing genus, of which C. gloeosporioides and C. boninense were the prevailing strains. Leaf and seedlings might be the main path of infection. Endophytic fungi and pathogen might convert to each other, influenced by such factors as environment, genotype et al.
Keywords: Scrophularia ningpoensis; endophytic fungi; identification; phylogenetic analysis.
