Diversity of endophytic fungi in Pyrrosia sheareri(Bak.) Ching and the microstructure of its ground parts
摘要
Abstract
[Objective]Endophytic fungi resources and distribution regularity of Pyrrosia sheareri (Bak.)Ching were studied in order to provide references for better protection and management of P. Sheareri. [ Method ]The endogenous fungi from P. Sheareri were isolated into different parts (root, stem, leaf, and petiole) and identified based on morphological characteristics. The microstructure of the adventitious roots and rhizomes were observed using paraffin section and microtechnique. [ Result ]Fifty-three strains of endophytic fungi were separated from P. Sheareri, amongst which 50 strains belonged to 14 genera,7 families,5 orders, and 2 classes,while the other 3 strains belonged to Rhizoctonia and Sclerotium of Agno-mycetales. Phomopsis was the dominant genus in the 16 genera, accounting for 18.87% of the total strains, followed by Phyllosticta and Cephalosporium, which accounted for 15.09% and 13.21% of total strains, respectively. Adventitious roots of P. Sheareri have similar structure with primary roots of seed plants and the vascular bundle of rhizome had no cambium. [ Conclusion ] Endophytic fungi in P. Sheareri showed rich diversity; the cortical parenchyma was the main dwelling region for endophytic fungi.关键词
