自然界广泛地存在着高等植物与特定真菌共生的现象,真菌与高等植物的共生体叫做菌根。与木本植物共生的菌根菌大都是外生菌根菌,它可提高树木抗旱、抗高温的能力,还可制止或减少病原菌对营养根的侵染,改善营养吸收与促进生长。我国大型真菌种类丰富,其中不少是外生菌根菌,我们于1973—1982年调查了我国亚热带常绿阔叶林区以及其他地区,采到的23种外生菌根菌,并作生态分布分析。现报道如下。
The phenomenon of symbiosis between higher plants and specific fungi exists widely in nature, and the symbiont of fungi and higher plants is called mycorrhiza. Most of the mycorrhizal fungi which are symbiotic with woody plants are ectomycorrhizal fungi, which can improve the tree’s ability of resisting drought and high temperature. It can also stop or reduce the infection of pathogenic bacteria to the nutrient root, improve the nutrition absorption and promote the growth. Our country is rich in large fungi, many of which are ectomycorrhizal fungi. In 1973-1982, we surveyed 23 kinds of ectomycorrhizal fungi collected from subtropical evergreen broad-leaved forest and other areas in China, Distribution analysis. Report as follows now.
