- The powder character are phloem fiber bundles,crystal fibers(fibers with sheath of crystal cells),druse and secretory cells. 莖橫切面韌皮纖維束與篩管群、韌皮薄壁細胞相間排列 ,粉末中可見(jiàn)大量韌皮纖維束、晶纖維、分泌細胞、草酸鈣方晶及簇晶。 理化鑒別特征 :可能含有黃酮類(lèi)成分 ;
- 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. 維管形成層:由于維管束內形成層和束間形成層的活動(dòng)產(chǎn)生的環(huán)狀形成層結構,它的分裂活動(dòng)可以形成次生木質(zhì)部和次生韌皮部。
- 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. 研究結果表明,分泌道分布在根中柱鞘組織和次生韌皮部、莖韌皮部和髓,以及葉脈韌皮部?jì)群湍举|(zhì)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. 它縱貫于根,莖等器官的木質(zhì)部和韌皮部之間,是具有分生能力的組織。通過(guò)形成層的分裂可以在木本的雙子葉植物中形成次生木質(zhì)部和次生韌皮部。
