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。
-

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。

cambium:形成层
它包括形成层(cambium)和木栓形成层(cork cambium或phellogen). 形成层的活动能使根和茎不断增粗,以适应植物营养面积的扩大. 木栓形成层的活动是使长粗的根、茎表面或受伤的器官表面形成新的保护组织.
-
cork cambium:木栓形成层
维管形成层向内分化成次生木质部,向外形成次生韧皮部. 维管形成层的活动,使得植物根茎加粗,但也会导致植物外部的组织受此张力而损坏. 植物通过木栓形成层(cork cambium)的活动来不断补偿损失的外部.
-
interfascicular cambium:束间形成层
当茎进行次生生长时,首先是位于初生木质部与初生韧皮部之间的束中形成层(fascicular cambium)细胞开始分裂、生长分化,接着与束中形成层相连接的髓射线细胞恢复分裂能力,转变为束间形成层(interfascicular cambium).
-
fascicular cambium:束中形成层
当茎进行次生生长时,首先是位于初生木质部与初生韧皮部之间的束中形成层(fascicular cambium)细胞开始分裂、生长分化,接着与束中形成层相连接的髓射线细胞恢复分裂能力,转变为束间形成层(interfascicular cambium).
-
phellogen:木栓形成层
次生分生组织包括木栓形成层(phellogen)和维管形成层(vascular meristem)(尤其是束间形成层),主要分布于根茎器官的内侧,并与其长轴相平行,与根茎的逐年增粗直接相关(图2-3).
