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.

From the base to the crown in axial, the vessel-elements proportion increases in fluctuation, contrary to the ray proportion. The fiber proportions in the regions of base and crown are less than that in the trunk of tree, and fluctuate at 65% or so. The parenchym proportion increases quickly to the 1.3m height of tree, reaching the maximum at 9.52%, and then decreases quickly to the 3.3m height of tree (8.90%); afterward it leveled off and increases slightly.

组织比量轴向变异表现为随树高增加导管比量波动性递增，与木射线比量相反；纤维比量在近根区和近冠区稍小，而主干部稍大，并在65%左右波动；轴向薄壁细胞比量先随树高增加急剧增加，到1.3m树高处达最大值（9.52%）后又急剧降低至3.3m树高处的8.90%，以后基本稳定并在波动中略有增加。

The fiber length has only little influence on the basic density within the growth rings, and significant correlation at 0.01 levels was found between the basic density and the fiber length among the different rings. Only slight negative correlation was found between the basic density and the fiber width within the growth rings, but significant positive correlation at 0.01 levels was indicated between the basic density and the fiber width among the growth rings, contrary to that of fiber length. It was demonstrated that significant positive correlations at 0.01 levels between the basic density and fiber double wall thickness, fiber length to width ratio and double wall thickness to diameter ratio, significant negative correlations at 0.01 levels between the basic density and fiber diameter and diameter to width ratio, only slight negative correlation between the basic density and fiber width both in the same growth rings and among the different growth rings. No significant correlation was found between the basic density and the vessel morphological features, nor was the tissue proportion in the same growth rings. But among the different rings, it was found there was significant positive correlation at 0.01 levels between the basic density and the fiber proportion among the different rings, and significant negative correlation at 0.01 levels between the basic density and vessel-elements proportion and ray proportion, only slight negative correlation between the basic density and the parenchym proportion. Significant or no significant negative correlation was found between the basic density and the microfibril angle in the same growth rings, but significant negative correlation was found between the basic density and the microfibril angle among the different growth rings.

生长轮内纤维长度对基本密度的影响不大，而在不同生长轮间纤维长度与基本密度达极显著正相关，纤维宽度与此相反，同一生长轮内纤维宽度与基本密度极显著负相关，不同生长轮间只有微弱负相关；基本密度与纤维双壁厚、长宽比、壁腔比在生长轮内和生长轮间均呈极显著正相关，而与胞腔直径、腔径比均呈极显著负相关，仅与纤维宽度呈微弱的负相关；导管形态对基本密度的影响不显著；同一生长轮内组织比量对基本密度的影响也不显著，但不同生长轮间基本密度与纤维比量呈极显著正相关，与导管比量和木射线比量呈极显著负相关，与轴向薄壁细胞比量仅呈不显著负相关；生长轮内基本密度与微纤丝角呈显著或不显著负相关，但在生长轮间这种负相关达到极显著水平。

The antiquity of Schisandraceae is supported by the presence of single vessel, scalariform perforation plates with many bars, scalariform vessel pitting and heterogeneous rays.

在五味子科中发现木材导管单生、具梯状穿孔板、导管壁具梯形排列的纹孔以及木射线异型等原始性状，支持五味子科在被子植物中的原始地位。

Parviflora in shrub communities had the xeromorphic traits in the aspects of ① their secondary xylem had shorter vessel elements, higher vessel frequency, less single porous percentage, lower rays, higher relative conductivity and lower vulnerability index, and ② their leaf had lower water potential, lower water content and free water content, higher bound water content, high ratio of bound to free water content, and less specific leaf area.
