P - procambium 中文 - EN166

procambium n.【植物；植物學】原形成層。adj.-bial

procarp
Signals were strong in the cell periphery of procambium , and longitudinal signals were stronger than lateral ones ; in root ground meristem cytoplasm , concentration in the perinuclear region was stronger than one in the cell periphery . in cell periphery of root ground meristem , distribution of actin mrna was heterogeneous , longitudinal signals were stronger than lateral ones ; in callus meristem cytoplasm , concentration in the perinuclear region was low ; 這表明，從棉花愈傷組織薄壁細胞到鳥巢狀管胞團再到正常苗的過程中肌動蛋白mrna的分布和濃度都有明顯的變化，而在這里愈傷組織在分化到鳥巢狀管胞團后就不再繼續發育，因而推測，肌動蛋白mrna分布和濃度可能影響愈傷組織分化出正常的植株。
7 - 10 days “ seedlings after the seeds germinated , the meristem in the stem apex functioned to form true leaf primordium , meanwhile , the vessel elements which differentiated from parenchymatous cells of the middle and upper portion of the cnz connected with the vessel elements from procambium of epcotyl - shoot region 種子萌發7 - 10天，幼苗的莖端分生組織活動形成真葉雛形，此時由子葉節區中、上部薄壁細胞的轉分化形成的導管分子與上胚軸-苗區原形層形成的導管分子發生連接。
Primary vascular tissue , which is found in all vascular plants , is formed from the procambium 初生維管組織由原形成層發育而來，在所有維管植物中都有存在。
Procambium ( procambial strand ) the layer of cells that gives rise to the vascular tissue 原形成層（原形成層束）：形成維管組織的一層細胞。
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。
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。
The stele includes all primary tissues derived from the procambium consists of pericycle，phloem and xylem . 中柱包括從原形成層衍生而來的全部初生組織，由中柱鞘、韌質部和木質部組成。
Cells of the procambium and ground meristem are more vacuolated than those of the protoderm . 原形成層和基本分生組織的細胞比原表皮層細胞更加液泡化。
