secondary phloem
解釋
次生韌皮部-
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。 -
Albuminous cell 1. a vertically elongated parenchyma cell, found in groups in the rays of the secondary phloem in gymnosperms, where they are associated with sieve cells
蛋白質細胞： 1 .在裸子植物的次生韌皮部薄壁組織和韌皮射線中發現的1種垂直伸長的細胞，通常與篩胞相結合。 -
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
在尚未木質化的植物中，它是唯一的輸送有機營養的組織，但在具有次生生長的成熟植物體中，該功能由次生韌皮部行使。 -
The protein accumulated mainly in secondary phloem parenchyma cells and secondary phloem ray cells. the degradation of storage protein in terminal branchlets of swietenia macrophylla synchronized with new shoot growth after leaf - absent period, suggesting that the protein was utilized to support the growth of new shoots. when the diminishing of the storage protein below the girdled site was blocked, the new shoot growth was also restrained
在樹木新的年生長周期中，隨著新梢的發育，積累在末端小枝中的貯藏蛋白質開始被消耗新梢葉片成熟時，末端小枝中的18kda和21kda蛋白質己完全消失，而樹乾和大根中的這兩種蛋白質的含量相對穩定，與落葉期相比幾乎沒有變化。 -
The secondary phloem parenchyma cells and secondary phloem ray parenchyma cells were the preferential sites for protein storage to the xylem parenchyma cells whereas a large amount of vegetative storage proteins was present in xylem, especially in the primary xylem and the inner secondary xylem of the extended stems
營養貯藏蛋白質優先在次生韌皮部的韌皮薄壁細胞和韌皮射線薄壁細胞中積累，在新梢伸長生長停止后，新梢基部莖的木質部中也積累了相當數量的營養貯藏蛋白質，主要分佈在初生木質部和內側次生木質部的各種生活的薄壁細胞中。
