| Abstract: | Armillaria mellea penetrated protocorms from seed germination and vegetative multiplication corms of Gastrodia elata 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 cells. Gastrodia elata seeds depended on digesting Mycenct 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. |
