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.

The results showed that POD activity increased at first and then decreased in the skin and flesh of root. The peak occurred at 40 d and 60 d in the skin and flesh, respectively. POD activity in the skin was higher than that in the flesh at 30 d and then contrary results were observed. The higher POD activity was, the more POD isoenzyme was. The pattern of POD isoenzymes was different between skin and flesh at different vegetative growth stages. POD isoenzymes in the skin were composed of five monomers and four dimers while five dimers or two monomers, two dimers and one tetramer in the flesh. POD isoenzymes in the root were mainly acidic. POD localized mainly in the cell walls of periderm, cambium, xylem ray, xylem vessels and primary xylem.
结果显示，心里美萝卜营养生长期肉质根的皮和肉中POD活性均先升高后降低，分别在播种后第40 d和60 d出现峰值，30 d时皮中POD活性高于肉，之后则相反，酶活性最高时同工酶数目也最多，不同时期，皮和肉中同工酶种类不同；皮中POD同工酶由5个单体和4个二聚体组成，而肉中由5个二聚体或2个单体、2个二聚体和1个四聚体组成，均以酸性同工酶为主；组化定位显示POD主要分布在肉质根的周皮、形成层、木射线、木质部导管和肉的初生木质部等的细胞壁附近。

The wood anatomy of 21 collections of 7 species within Kadsura Kaempf. ex Juss. and 14 collections of 8 species of Schisandra Michx., representing a large proportion of two genera in Schisandraceae, was investigated using light microscopy and scanning electron microscopy. Several features in the secondary xylem, such as types of vessel elements, arrangement of vessel-ray pitting, types of ray and shape of the body ray cells, show consistent characteristics at the family level, which support the view that Schisandraceae represents a monophyletic group.
