形成层

Wood is the product of cambial activity in trees, and the seasonal activity style of cambium directly influences wood biomass production, structures and properties.

木材是树木形成层细胞分化的产物，形成层的活动方式不仅影响木材的产量，而且影响木材的结构和性质。

It is continuous with the intrafascicular cambium.

在幼嫩的茎和根中，可看到原形成层进一步发育成束内形成层，后者的分裂活动产生了初生维管组织。

In most dicotyledonous roots showing secondary growth.the pericycle is also involved in the origination of the vascular cambium and the phellogen.

在大多数双子叶植物根中有次生生长。中柱鞘也与维管形成层和木栓形成层的起源有关。

The PROTOPHLOEM and METAPHLOEM are primary tissues and derived from the procambium,while the secondary phloem is formed from the VASCULAR CAMBIUM.

原生韧皮部和后生韧皮部属于初生组织，来源于原形成层，而次生韧皮部由维管形成层产生。

Life of cork cambium is only one year, later it also is changed into cortex cells, so that the new cork cambium will appear in inner of the periderm. Finally, it can form in parenchyma cell of secondary phloem.

木栓形成层的寿命只有一年，随后转为木栓，所以新的木栓形成层将出现在周皮的内方，最后木栓形成层可以由次生韧皮部薄壁细胞形成。

There are two zones of cambium: the VASCULAR CAMBIUM, which produces secondary xylem and phloem, and the PHELLEM, which produces secondary cortex and cork or bark.

有两种类型的形成层：一种是维管形成层，产生次生木质部和次生韧皮部。另一种是木栓形成层，产生次生皮层，软木或树皮。

The secondary xylem of woody plants is a product of the vascular cambium,its formation is a complicated type of plant cell differentiation, including cambium initiation, cambial cell division, cell expansion, secondary wall deposition and programmed cell death.

木本植物的次生木质部是维管形成层的活动产物，其形成过程是植物细胞分化的一种复杂类型，包括维管形成层发生、形成层细胞分裂、分化、细胞扩展、次生壁形成和细胞程序化死亡等阶段。

Vascular cambium The ring of CAMBIUM formed by the activity of the interfascicular cambium and the intrafascicular cambium that gives rise to secondary xylem and secondary phloem.

维管形成层：由于维管束内形成层和束间形成层的活动产生的环状形成层结构，它的分裂活动可以形成次生木质部和次生韧皮部。

The interfascicular cambium and INTRAFASCICULAR CAMBIUM link into a complete cambium cylinder that cuts off secondary xylem tissue to the inside, secondary phloem tissue to the outside, and parenchyma cells both sides.

束间形成层和束中形成层组成一个完整的形成层环。形成层以内为次生木质部，形成层以外是次生韧皮部。薄壁组织细胞形成维管射线。

The secondary growth mainly depend on the activities of vascular cambium and cork cambium; the cork cambium originates from pericyclic cells.

次生生长主要是由维管形成层和木栓形成层的活动完成，木栓形成层起源于中柱鞘细胞。

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

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
