其中，抗寒种类淀粉粒小且水解彻底，还原糖含量高，脂类物质在形成层处高度聚集。

The main cause of root tuber expanding is that phellogen produces many layers of phelloderm parenchyma cells and vascular cambium produces a lot of secondary vascular tissue that consists of parenchyma.

但在以后的发育过程中，木栓形成层产生了多层栓内层薄壁细胞，维管形成层则产生了大量高度薄壁组织化的次生维管组织，从而形成了肉质膨大的块根。

This system simulated in vivo the processes of cambium occurrence, cell differentiation and xylogenesis.

Vascular cambium has formed, but the secondary structure is far from developed.

维管形成层已经形成，但次生结构尚不发达。

The mechanism for the initiation and activity of vascular cambium

维管形成层发生和活动的机理

The present results indicated the remarkable impact of salt stress on cambium cell activity and secondary xylem cell differentiation of both root and stem.

Meanwhile, paraffin-cut section method was used for studying on callus formation, cork cambium and vascular cambium initiation.

同时，运用石蜡切片法研究剥皮后愈伤组织的形成、木栓形成层和维管形成层的发生；

, 6-BA induced the division of vascular cambium and cortex cells.

6-BA诱导维管束中发生形成层以及诱导皮层细胞启动。

It was analysed that the phenomenon was related to the divide and differentiate of vascular cambium cell.

分析此现象可能与维管形成层细胞的分裂分化作用有关。

The base of scoin is cut diagonally to expose a large oval of cambium.

接穗的基部被切成斜形,暴露出椭圆形的大圈形成层.

However, before forming the cork cambium, pericyclic cells produced many layers pericyclic parenchyma cells by periclinal division.

但中柱鞘细胞在形成木栓形成层前，先进行平周分裂，形成了由多层细胞组成的中柱鞘细胞环。

The callus originated from several parts , but mainly from cambium.

愈伤组织是多起源的, 但主要源于形成层.

After vascular cambium cells divide, the progeny cells on the interior side become xylem parental cell.

维管形成层细胞分裂后，在内侧分裂出来的细胞成为木质部的母细胞。

Roots are different in the width of supernumerary cambium and phelloderm and the cell.

生长龄不同，额外形成层、栓内层的宽度和细胞大小不同。

With the progressive development of stem, the activity of vascular cambium began. The fascicular cambium differentiated into secondary xylem and secondary phloem, while the interfascicular cambium only differentiated into wide ray of parenchyma tissue.

随着茎的继续发育，维管形成层开始活动，由束中形成层产生次生韧皮部和次生木质部分子；而束间形成层仅产生薄壁细胞组成宽的射线。
