Annual dynamic of the main root of Panax ginseng shows that the cross-section 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.
人参主根的年度动态表明，各组织的横截面积随年龄逐渐增加，但横切面上韧皮部与木质部的比例降低。季节性动态表明，木栓形成层和形成层细胞在6 - 7月活跃分裂，8月则减缓。生态条件会影响主根结构的年度和季节性动态。
