The structures of the two-year-old tap roots are similar to that of the one-year-old ones, while the periderm thickness is increased. In the secondary xylems of the two-year-old roots, the woody fibers are distributed in groups and the interxylary phellem appears. The vascular rays are multiseriate. Phellem cells surround a sclereid form the phellem cycle in the phloem nearby the periderm.
二年生黄芩主根的主要结构与一年生的基本相同，其不同之处为：二年生主根的周皮增厚，次生木质部中木纤维成群分布，出现木间木栓；维管射线为多列且明显；在近周皮的韧皮部内出现包围石细胞的木栓环组织。

As the plants grew for a longer time the cells in the phellem of the taproots become smaller in size and closer in arrangement and calcium oxalate crystal declined in quantity in the phelloderm of the taproots all the taproots had three secretory canals but on average the calibers of the canals gradually become smaller the parenchyma cracks in outer phloem and the xylem part near the root center gradually increased in size ,and the area ratios of phloem to xylem continuously decreased the vessel and vessel-layer numbers in secondary xylem of the transplanted .
不同生长年份的移山参主根结构具有一定差异：随生长年份的增长，木栓层细胞体积变小，排列趋于紧密；栓内层草酸钙结晶越来越少；分泌道均为3轮，但平均口径逐渐减小；韧皮部外侧和木质部靠近根中央处的薄壁组织的裂隙逐渐增大；韧皮部与木质部的面积比则不断下降；12年，16年生移山参主根次生木质部中导管数量和层数明显多于8年生。

From the beginning of germination, radicle spread out and down from the seed capsule.
植物从种子萌发开始，胚根从种皮中伸出并向下生长，这种从胚中长出的根称为主根，随着生长过程的进行，又会在主根上长出侧根，而当侧根长到一定的时候又会长出次一级的侧根，这样不断生长就形成了一个植物的根系。
