| 1 | Microstructure and Ultrastructure Changes of Panax ginseng Root Tip that Infected by Cylindrocarpon destructans at Early Stage显示文摘[Objectives] To study the microstructure and ultrastructure changes of P. ginseng root tip infected by C. destructans. [Methods]The paraffin section and superfine slice were used to observe the microstructure and ultrastructure of root tip of P. ginseng,respectively.[Results] Microstructure and ultrastructure observation indicated that,the morphology and structure of epidermal cells of P. ginseng were regular,cells had abundant contents,and organelles were easy to observe in control. However,after infected by C. destructans,the cell walls were thicken seven days post inoculation,particles were deposited in epidemic cells and pith,cell walls were broken,and cells began to disintegrate. Furthermore,morphology of cells was abnormal and contents in cells were decreased when infected by C. destructans. The organelles were break up,and difficult to be distinguished. [Conclusions] Through the results we deduced that,the hypha of C. destructans should firstly invade the epidermal cells of P. ginseng,and then enter into the xylem of P. ginseng root through the intercellular space,which obstructed the transport of water and inorganic salt,and finally led to death of ginseng seedlings. | Yuan GAO Wanlong DING Rong WANG Yong LI | 2018 | Medicinal Plant2018，9，1： | 0 |
