Studies on the Morphological Changes of Intracellular Structures of Gastrodia elara Bl.in the Period of Hyphae Digested

Liu Cheng-yun   

Abstract: A primary study on the process of Hyphae Digested of Gastrodia elata BI. has been made through cytological and idstoebemieal methods. 1. When the cortical ceils of Gastrodia elata corm had been infected by Armillaria mellea Fr., its vacuole disrupts and disappears in the protoplast, so that the hyphae were changed in nature and then hydrolyzed; The cells themselves too, were bydroiyzed at the same times. In our inference, this period of hydrolysis happens because of the function that the vacuole release the hydrolases. Thus, the cells and fungal hyphae have been changed in their form and histoehemisty. 2. During the changes of cortical cells of corm, the outer-most part of the columella parenchyma cells also changs greatly, such as the appearing of renewable nuclei, the changes of the form and the structures of nucleoli, the disappearing of polysaccharide particles, the increasing of the content of RNA, the increasing of mitochondrias in large quantity etc. All these changes show the active process of synthesis in the large cells.
