Studies on the Morphology and Anatomy of Root, Stem and Rhizome of Schisandra chinensis (Turcz.) Baill
摘要
Abstract
The anatomical structure of root, stem and rhizome of Schisandra chinensis (Turcz.) Baill were studied by using paraffin sections and transmission electron microscope, under the different development stages to analyze their developmental process to find the different microstructures of rhizome from root and stem. The results showed that: ① the development process of rhizome was similar to stem which could be divided into three stages of promeristem, primary and secondary growth. However, those two were different in ultrastructure of primary growth, tip type and secondary structure. There was a special membrane clinging on the first layer cell of stem tip, and it was much more developed than rhizome tip with completed envelope, more plastids and less vacuoles, while the rhizome tip had more vacuoles and lipid droplets. There had other differences between the two tips, the rhizome tip was bendy, the proportion of secondary growth of rhizome was less than that of stem. ② Secondary structure of root was composed of merisderm, cambium layer, secondary xylem and secondary phloem with the parenchyma cells of non-lignification during the secondary growth process. The developing patterns of primary structure of rhizome was endarch, which was different from that of root.关键词
