摘要:
为了弄清水杉(Metasequoia glyptostroboides Hu et Cheng.)内生真菌的种类及分布特点,通过采样、分离、培养与鉴定,对信阳地区栽培的水杉内生真菌的群落结构及生态分布进行了研究。结果表明:水杉内生真菌具有丰富的生物多样性,分离得到25种真菌。其中,产孢真菌有17属20种,均为半知菌,未产孢真菌有5种。研究表明:拟茎点霉(Phomopsis sp.)、链格孢菌(Alternaria sp.)、刺盘孢菌(Colletotrichum sp.)、大茎点霉(Macrophoma sp.)4种真菌是水杉内生真菌优势种; 内生真菌在水杉各组织均有定殖,定殖率总体达53.5%。宿主生境是影响内生真菌群落结构及真菌多样性的主要因素,组织类型对内生真菌的分布也有重要影响。
Abstract:
In order to know the community and ecological distribution of endophytic fungi in Metasequoia glyptostroboides, the community structure and ecological distribution of endophytic fungi in Metasequoia glyptostroboides grown in Xinyang were studied by sampling, isolating and identifying. The result showed that the biological diversity of the endophytic fungi was rich. Twenty five fungi were obtained in this study. Among them, twenty sporulated fungal species belonged to deuteromycetes and other species were non-sporulated fungi. The study also showed that Phomopsis sp., Alternaria sp.,Colletotrichum sp. and Macrophoma sp. were dominant fungi. The endophytic fungi could be isolated in every tested plant parts of Metasequoia glyptostroboides and their colonization rate was 53.5%. Habitat and tissue type of the plants were main factors that affected the biological diversity and community of the endophytic fungi mostly. The study could provide basic data for studying and using of endophytic fungi.
