摘要
蜜环菌(Armillaria mellea Fr.)以菌索形态侵染天麻(Gastrodia elata Bl.)种子发芽的原球茎及营养繁殖茎,首先在皮层最内一层细胞形成菌丝通道和菌丝流,然后向内侵入大型细胞、向外侵入皮层细胞。天麻在有性繁殖阶段,靠消化侵入种胚的紫萁小菇等萌发菌获得营养而发芽,无性繁殖阶段,营养繁殖茎消化蜜环菌才能正常生长。
Armillaria mellea penetrated protocorms from seed germination and vegetative multiplica- tion corms of Gastrodia clara with rhizomorph.At beginning,they formed a hypha passing road and a hypha flow in the inner cells of cortex,and then,they both penetrated inside of large cells and penetrated outside of cortical ceils.Gastrodia elata seeds depended on digesting Mycena osmundicola etc gain nutrition to germinate at the stage of sexual reproduction,but its corms of vegetative multiplication must be penetrated by Armillaria mellea obtaining nutrition for normal growth at the stage of vegetative propagation.
