摘要
人参主根年度动态表明各组织的横切面积随参龄增大而增大,但韧皮部与木质部之比逐渐下降。季节动态为木栓形成层和形成层活动6～7月旺盛,8月减弱。生态条件对主根结构的年季性动态有影响。
Annual dynamic of the main root of Panax ginseng shows that the cros(?)ection of various tissues increases gradually with age, but the ratio of phloemxylem in cross-section decreases. Seasonal dynamic shows that cells of phellogen and cambium divide actively in June～July and gets retarded in August. Ecological conditions can influence annual and seasonal dynamics of the structure of the main root.
