vascular cambium

Secondary vascular tissue, found only in plants with secondary thickening , develops from the vascular cambium.

次生维管组织由维管形成层发育而来, 仅存在于有次生加厚的植物中.

The mechanism for the initiation and activity of vascular cambium

维管形成层发生和活动的机理

Continually increase of Vascular cambium cells and formation of a root initial;

薄壁细胞不断分裂，形成不定根原基发端细胞；

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。

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。

, 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。

The secondary growth mainly relied on activities of vascular cambium and cork cambium.

次生生长主要是依靠维管形成层和木栓形成层的活动来完成。

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。
