黄山地区松树林外生菌根菌资源及生态分布

1998～2003年,对黄山地区松树林下外生菌根菌资源及生态分布进行了调查,鉴定出外生菌根菌43种,隶属于10科17属.其中马尾松林下有43种、黄山松林下有12种.马尾松幼林下的外生菌根菌种类单一,彩色豆马勃、硬皮马勃类为优势菌种;马尾松成熟林下外生菌根菌种类丰富,其优势种类为红菇科、鹅膏菌科、牛肝菌科和鸡油菌科的一些种类.并分析了树种植被对外生菌根菌分布的影响,菌根真菌的分布与温度、湿度及土壤条件的关系.

Resource and ecological distribution of ectomycorrhizal fungi under pine forests of Huangshan Mountain district

Pinus massoniana and Pinus taiwanensis are the most common and important tree species in the Huangshan Mountain district, and ectomycorrhizae plays an important role in their forestation. Our investigations in 1998-2003 showed that under the pine forests of this district, there were 43 species of ectomycorrhizal fungi belonging to 10 families and 17 genera, of which, 43 were under Pinus massoniana forest, and 12 under Pinus taiwanensis forest. Only a few species were found under young Pinus massoniana forest, with the dominant of Pisolithus tinctorius (Pers.) Coken and Rhizopogon spp., but under mature Pinus massoniana forest, there were plentiful species, with the dominant of Russulaceae, Amanitaceae, Boletaceae and Canthurellaceae. The relationships between woody species and ectomycorrhizal fungi, and between fungi distribution and temperature, moisture and soil condition were discussed in this paper, which would benefit to the further studies on the effects of different ectomyrrhizal fungi to Pinus massoniana and Pinus taiwanensis forests.
