四川桉树外生菌根真菌的研究

The Study on Ectomycorrhizal Fungi Associated with Eucalyptus in Sichuan

通过野外调查和室内鉴定 ,已查明在四川与桉树共生的外生菌根真菌共 17种 ,隶属 9科 11属 ,其中钟形斑褶菇为国内外在桉树林中首次报道 ;通过不同生态区域固定标准地详细调查揭示了外生菌根真菌的分布随树龄、温度、湿度及土壤条件变化的规律 ,并认为四川桉树人工林下出现的彩色豆马勃 ,紫晶腊蘑 ,大孢硬皮马勃 ,光硬皮马勃属于森林菌根菌演替序列中的早期外生菌根菌 ,与晚期菌根菌相比 。

species belonging to 9 families, 11 genera were found to be associated with Eucalyptus in Sichuan through outdoor investigation and microscope examination. Among them, Panaeolus campanulatus was reported to be an ectomycorrhizal fungi to Eucalyptus at home and abroad for the first time. The rule that fungus distribution varied with tree age, temperature, humidity and soil condition was also revealed by the means of fixed standard land in various ecological regions. It is concluded that Pisolithus tinctorius, Laccaria amethystea, Scleroderma bovista, Scleroderma cepa, the early stage fungus in mycorrhizal fungus orderly succession, are more adaptable than the late stage fungus in Eucalyptus forest in Sichuan.
