vascular cambium
解釋
維管形成層-
Secondary vascular tissue, found only in plants with secondary thickening, develops from the vascular cambium
次生維管組織由維管形成層發育而來，僅存在於有次生加厚的植物中。 -
Intrafascicular cambium ( fascicular cambium ) the part of the vascular cambium within the vascular between the xylem and phloem
束中形成層：是位於木質部和韌皮部構成的維管束內的一部分維管形成層。 -
Ecbp21 distributed more in vascular bundle and split sect such as cambium and stigma, and mainly in cell wall area
Ecbp21在形成層、花拄頭等分裂旺盛的部位以及維管束中分佈更多，並且多分佈於細胞壁區域。 -
The vascular cambium extends to form a complete ring of meristematic tissue around the stem, the separate vascular bundles being linked by interfascicular cambium
維管形成層向兩側延伸直至形成一個莖內的分生組織環，各個維管束被束間形成層聯系在一起。 -
We have observed the following characteristics of anatomical structure and development : ( 1 ) the primary roots belong to archetype and the lateral roots occur in the position toward the xylem of the vascular cylinder ; ( 2 ) the root endodermis consists of thicken casparian strips, and there are from two lo four layers parenchyma cells near the pericycle ; ( 3 ) the pith and resins canals are absent in the toots ; ( 4 ) secondary structure occurs in the root hair zone, and vascular cambium is formed from the parenchyma cells between the primary xylem and primary phloem ; ( 5 ) tanning materials are abundant in pericycle cells and phelloderm cells ; ( 6 ) sclereids are found in secondary phloem, and rays are rather rich in secondary xylem
結果表明：氣生不定根具有以下結構特徵和發育特點： （ 1 ）根為二原型，側根正對著木質部發生； （ 2 ）幼根內皮層細胞具凱氏帶加厚，維管柱內緊挨中柱鞘內側具有2 ~ 4層大型薄壁細胞； （ 2 ）根中無髓和樹脂道； （ 4 ）次生結構發生於根毛區，維管形成層由初生木質部和初生韌皮部之間的薄壁細胞轉化形成； （ 5 ）中柱鞘和栓內層細胞富含單寧類物質； （ 6 ）次生韌皮部有石細胞，次生木質部射線發達。 -
The tissue - localization showed that there were more silver - grains labelled in the ray, callus and regenerated differentiating vascular tissue cells than that in other tissues. it further suggested that the high concentration of endogenous iaa triggered the dedifferentiation of the immature vascular tissues after girdling, and the lower concentrated iaa flow could promote the initiation and activity of the regenerated cambium
內源iaa組織定位的結果表明射線細胞愈傷組織和新生維管組織內均有較多的銀顆粒標記。這些似可表明，高濃度的內源iaa可啟動未成熟維管組織細胞的脫分化，而較低濃度的內源iaa流則可誘導再生形成層的發生和活動。
