| Abstract: | The growth of Gastrodia elata Bl. and Armillaria mellea (Vahl. ex Fr.) Quel. shares a special symbiotic relation. In general, A. mellea invades the G. elata , the epidermal cells, the cortical cells and the large cells of the growing vegetative propagation corm of G. elata . The empty cavity cells, the cork cells of the isolation in the vegetative propagation corms and the large cells of G. elata were the defensive structure, protecting the new G. elata from pathological invasion by A. mellea . In winter, G. elata enters the stage of hibernation. The faulting layer derived from the cork cells of the isolation was the last defensive structure by which new G. elata could safely live through the winter. |
