- The PROTOPHLOEM and METAPHLOEM are primary tissues and derived from the procambium,while the secondary phloem is formed from the VASCULAR CAMBIUM. 苯丙氨酸是苯化合物以及像箭毒和吗啡等生物碱的前体。
- 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;
- The tough outer covering of the woody stems and roots of trees, shrubs, and other woody plants. It includes all tissues outside the vascular cambium. 树皮,茎皮包在树、灌木和其它木本植物的根部、茎部的硬皮,包括维管形成层外的所有组织
- Vascular cylinder of adhesive disc turned into vascular bundles while adhesive disc enlarged, and the active stage of vascular cambium was short. 吸盘膨大时维管柱转变成维管束,维管形成层活动期较短。
- 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。
- In plants with secondary growth, the vascular cambium, originating between the xylem and the phloem, forms a cylinder of tissue along the stem and root. 而在双子叶和单子叶植物的排列又有所区别。中柱鞘是初生分生组织。它是侧根,木栓的发源。同时,根的次级生长,主要是维管束的次级生长,也是中柱鞘运动的结果。
- There are two zones of cambium: the VASCULAR CAMBIUM, which produces secondary xylem and phloem, and the PHELLEM (cork cambium), 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。
