procambium 中文意思是什麼
procambium
解釋
n. 名詞 【植物；植物學】原形成層。adj. 形容詞 -bial
-
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。 -
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的分佈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分佈和濃度可能影響愈傷組織分化出正常的植株。 -
