But when we examined the structure of cultivar of D. huoshanense, endomycorhiza was founded unexpectedly. And in the wild type of D. huoshanense, fungi was also founded in its stems and leaves. So the author thought that endomycorhiza is not only located in the roots of Dendiobium plants, but also exists in other organs of plants, including stems, leaves. As plant produces seeds, mycorhiza could enter into the cells of seeds. When mature seeds germinate in media, the endomycorhiza enter into the roots of cultivar.
石斛属植物与真菌共生,根为菌根,作者在研究霍山石斛组织培养型结构时发现,组织培养苗的根部也分布有真菌,而且在野生霍山石斛的茎、叶中发现有真菌,作者因而指出,真菌并不是完全分布在根部,而是遍布于整个植物体,推测植物形成种子时,真菌进入种子,所以在组织培养时,真菌随着种子的萌发,进入植物体根部。
