在安徽省黄山天都峰上,有棵名为探海松的绿树。它立悬峭壁,俯视云海,形象生动,妙趣横生。其实,像这种“咬定青山不放松,立根原在破岩中”的苍松翠柏,在我国何止万千！为什么在悬崖石缝的恶劣环境中会长出参天大树呢?这要归功于树木根部一种膨大变形的菌根。菌根是真菌的菌丝在植物根部形成的特殊构造。形成菌根的真菌叫菌根菌。真菌菌丝在根表面安家落户的称外菌根;在根内安居乐业的叫内菌根。
Peak in the sky in Huangshan, Anhui Province, there is a tree named sea pine exploration. It stands over the cliff, overlooking the sea of clouds, vivid, fun. In fact, like this “insisted Aoyama does not relax, the root of the original broken rock,” the pines and cypresses, in our country more than a thousand! Why grow tall trees in the harsh conditions of the cliffs? Thanks to an expanded mycorrhizal root at the roots of trees. Mycorrhiza is a special structure formed by fungal hyphae at the plant’s root. Mycorrhizal fungi form mycorrhizal fungi. Fungus mycelium settled in the root surface settled ectocarpus; in the root of the root canal called the inner mycorrhizal fungus.
