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。
The annual dynamics of the roots of ginseng showed that the cross-sectional area of each tissue increased with the increase of the age of participation, but the ratio of phloem and xylem gradually decreased. Seasonal dynamics for the formation of cork formations and cambium activity was strong from June to July and weakened in August. Ecological conditions have an impact on the seasonal dynamics of the main root structure.
