1·Rhubarb polysaccharide content is greater in phloem parenchyma than in xylem parenchyma. The mode of rhubarb polysaccharide production is gradual accumulation and storage.

与木薄壁细胞相比，韧皮薄壁细胞贮藏大黄多糖量相对较多，大黄多糖的贮藏和积累方式为逐渐累积。

3·Secondary xylem consists of pitted vessels, parenchyma fibers and rays.

次生木质部由孔纹导管、 薄壁组织及射线所组成。

4·Parenchyma in gall tissues were observed to occur hypertrophy or hyperplasia, and vertical tracheids in gall xylem were short and abnormal in shape.

瘤组织中的薄壁细胞均增生肥大，木质部的垂直管胞发生变形且变短。

5·Secondary structure occurs in the root hair zone, and vascular cambium is formed from the parenchyma cells between the primary xylem and primary phloem;

次生结构发生于根毛区，维管形成层由初生木质部和初生韧皮部之间的薄壁细胞转化形成；

6·SKC1 is preferentially expressed in the parenchyma cells surrounding the xylem vessels.

SKC1在木质部导管周围的薄壁细胞特异表达。
