词语大全 primary xylem中文翻譯

Primary xylem xylem derived from the procambium in the young plant
初生木質部：指幼嫩植物中來源于原形成層的木質部。

Protoxylem the primary xylem elements that are formed from the procambium first
原生木質部：初生木質部的成分，最早由原形成層形成。

In nonwoody plants the primary xylem is the only water - conducting tissue , but in mature plants with secondary growth this function is mostly taken over by the secondary xylem
在尚未木質化的植物中，初生木質部是唯一的輸水組織，但在具有次生生長的成熟植物中，該功能大多由次生木質部行使。

The process of vessel element \' s promotion , formation and connection in primary xylem of antirrhinum majus , a model plant , was observed through micropolariscope and bright - field microscope
利用偏光顯微鏡和明場顯微鏡，首次報道了模式植物金魚草幼苗初生維管系統木質部導管分子的發育、形成和連接過程。

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 cypnder ; ( 2 ) the root endodermis consists of thicken casparian strips , and there are from o 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 beeen 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征和發育特點： ( 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 )次生結構發生于根毛區，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 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，主要分布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。

More anthraquinone pounds was distributed in pith ray cells and the tissues of mature stem suchas bundle sheaths in large - scale vascular bundle , primary phloem and primary xylem than that in young stem . [ conclusion ] the distribution of anthraquinone pounds in the stem was of multilocus
結果隨著莖的不斷成熟，在莖的表皮、近表皮的1 ~ 2層皮層細胞及較內部皮層中，不同程度地增加貯藏和積累了一定數量的蒽醌類化合物，成為莖外部貯藏和積累蒽醌共化合物的主要結構部位成熱莖大型維管束的維管束鞘、初生韌皮部、初生木質部等組織和髓射線細胞分布了比幼莖多的蒽醌類化合物。
