- In nonwoody plants it is the only food-conducting tissue, but in mature plants with secondary growth this function is taken over by the secondary phloem. 在尚未木质化的植物中,它是唯一的输送有机营养的组织,但在具有次生生长的成熟植物体中,该功能由次生韧皮部行使。
- 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。
- They were accumulated in the large central vacuoles of secondary phloem parenchyma cells and secondary phloem ray cells. 这些蛋白质积累在韧皮薄壁细胞和韧皮射线细胞的中央大液泡里。
- Resin was synthesized by the active cells in the cambium zone including secondary xylem cells, cambium cells, secondary phloem cells and ray cells. 其形成的部位为当年的次生木质部,树脂道是由最幼嫩的木质部部分细胞分化形成。
- In the secondary phloem of Tree Peony metaphloem was dominative in the root's secondary structure, which was just opposite to Herbaceous Peony. 根次生结构,牡丹根次生韧皮部占主要部分,而芍药根次生木质部占主要部分。
- 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 secretory canals were distributed in the pericycle and secondary phloem of root, in the phloem and pith of stem, and in the phloem and above xylem of the vein in leaf. 研究结果表明,分泌道分布在根中柱鞘组织和次生韧皮部、茎韧皮部和髓,以及叶脉韧皮部内和木质部上方。
- The primary cambium is found in the stem and root between the phloem and xylem cells, and by division gives rise to the secondary phloem and xylem in woody dicotyledonous plants. 它纵贯于根,茎等器官的木质部和韧皮部之间,是具有分生能力的组织。通过形成层的分裂可以在木本的双子叶植物中形成次生木质部和次生韧皮部。
- These features may imply that, in branches of Zelkova serrata, the secondary phloem of the upper side (reaction phloem) may have a higher translocation efficiency. 此外,上侧次生韧皮部的筛管细胞较长也较宽,在两个筛管间具有的筛板亦较为水平排列,这些特徵可能意味著台湾榉的枝条上侧的次生韧皮部(反应韧皮部)具有较高的输送效率。
- As a result, tissues beyond the secondary phloem (including the epidermis and cortex, in many cases) tend to be pushed outward and are eventually "sloughed off" (shed). 根据木质部形成的脊的数目,可以把植物分为二原,三原,四原,五原和超过五个以上的多原。单子叶植物统书比双子叶植物有更多的脊(14左右)。
