形成层

The cork cambium gives rise to the PERIDERM, a protective layer of tissue on the outside of the stem or root, which consists of the cork, the phellogen, and the PHELLODERM.

木栓形成层的活动使周皮增厚，这种主要由木栓层、木栓形成层和栓内层组成的周皮是植物茎或根表面的保护层。

It is made up of the PHELLOGEN,which gives rise to the PHELLEM and PHELLODERM.

周皮来源于木栓形成层，木栓形成层分裂产生木栓层以及栓内层。

Study of the Transition from Procambium to Vascular Cambium In Erythrina Arborescens Roxb.

原形成层向维管形成层转化的研究。

Change in the concentration of endogenous IAA was measured with enzyme-linked immunosorbent assay, and the distribution of IAA-binding protein in the protoplasts in the cambial region was tested with an immuno-fluorescence technique, being improved by the authors, during the cambial active period in Broussonetia papyrifera L.

构树（Broussonetia papyriferaVent。）形成层活动周期中用酶联免疫吸附法测定了形成层区域的内源IAA浓度的变化，并用自行发展的免疫荧光检测方法测定了由此处生活细胞制得的原生质体中IAA结合蛋白的分布。

Our research work is currently focused on the molecular mechanisms of vascular cambium periodicity regulation and secondary xylem development, including cambial cell differentiation, secondary wall formation and programmed cell death.

本实验室以杨树、杜仲等树木作为实验材料，采用剥皮再生创伤系统和整体系统，研究维管形成层活动周期调控及形成层发生、次生木质部细胞分化、次生壁形成和细胞程序死亡的分子机理，为定向改良木材材质提供理论指导。

The cambial cells ceased to divide to produce secondary phloem cells at the end of July, but contineous to produce secondary xylem tissues until mid-August.

杜仲枝条中形成层在3月份开始恢复活动，同时产生木质部和韧皮部。7月底形成层细胞停止分裂，同时停止产生韧皮部，8月中旬停止产生木质部。

Adventitious roots differentiated after the induction time was 2 days and the rooting site was 0.3mm to the bottom of the petioles.Adventitious root came from fascicular cambium especially which was opposite to the vascular ray.

不定根发生进程的形态学观察发现，不定根发生部位为叶柄基部及向上至3mm处，不定根起始分化时间集中为诱导后2d，不定根发生起源于维管形成层，特别是维管射线正对的形成层。

Interfascicular cambium A single layer of actively dividing cells between the vascular bundles in stems.

束间形成层：束间形成层是位于茎的维管束间的具有旺盛分裂能力的一层细胞。

The vascular cambium extends to form a complete ring of meristematic tissue around the stem, the separate vascular bundles being linked by interfascicular cambium.

维管形成层向两侧延伸直至形成一个茎内的分生组织环，各个维管束被束间形成层联系在一起。

At 21 DAG, the newly established cambium cell started periclinal division, which would result in the production of phloem outwards and xylem inward. The 11-23 immature xylem cell layers beneath the surface continued their differentiation into mature xylem cells.

表面下7-11层未成熟木质部细胞在第7-14 DAG左右脱分化形成新的形成层。21 DAG，再生形成层开始平周分裂，产生新的韧皮部和木质部。11-23层未成熟木质部细胞继续分化为成熟木质部。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
