The primary meristem of the root tip may be extended a section of distance below the elongation region. ( biology) produced by metamorphosis. 根尖的初生分生组织可扩大到伸长区下方一段距离.(生物学)因变形而伸长的。
Cell divisions were diffused almost in the whole axis, and no primary thickening meristem occured. 结果表明:番红花球茎增粗生长是由于细胞分裂与细胞体积增大。细胞分裂几乎分散在整个轴上,没有初生增粗分生组织。
The results showed that the development of Bupleurum chinense DC. roots could be divided into four stages, promeristem, primary meristem, primary structure and secondary stages of growth. 结果表明,北柴胡根的发育包括原分生组织、初生分生组织、初生结构和次生生长4个发育阶段。
Anatomical structure of shoot apex on Angelica sinensis Genesis and Differentation of Primary Thickening Meristem in Shoot Apex of Sugarcane 当归营养苗端的解剖学观察甘蔗茎尖初生增粗分生组织的发生和分化活动
In the primary meristem of stem and the early stage of stem's primary structure, the essential oil was mainly distributed in glandular hairs; 在茎的初生、分生组织和初生结构形成早期,挥发油主要分布在茎表皮上着生的腺毛中;
In cells of the primary meristem and the front part of elongation zone, water stress could lead to acute increase of the gold particle density, and also in the cells of the elongation and root hair zone. 水分胁迫可导致初生分生组织或伸长区前部细胞金颗粒标记密度大增,伸长区中部及根毛区细胞的金颗粒密度也明显增加。
Primary meristem of stem is composed of protoderm, procambium and ground meristem. 分枝列当茎的初生分生组织由原表皮、原形成层和基本分生组织组成。
Studies on the cell division of primary thickening meristem and apical meristem of the shoot apex in sugarcane 甘蔗茎尖初生增粗分生组织与顶端分生组织细胞分裂研究
In the early stage, the cellular group of the primordium will differentiate into both of interior and exterior tissues, namely, exterior parenchyma and the saccular primary thickening meristem ( PTM) adjacent to the inside as well as interior parenchyma. 初期,原基细细胞团分化为内外两部分组织:外侧为薄壁组织及紧邻其内的囊状初生加厚分生组织,内侧为薄壁组织。
Leaves could be divided into three stages: promeristem, primary meristem and mature structure. The leaf of Bupleurum chinense DC. 北柴胡叶的发育包括原分生组织、初生分生组织及成熟结构3个阶段。
The development of leaf includes original meristem, primary meristem and mature structure of three stages. 叶的发育包括原分生组织、初生分生组织和成熟结构3个阶段,其叶为典型的等面叶。
In the primary thickening process of the Phyllostachys edulis shoot bud, the contributions of different tissues were arranged as follows: pith meristem vascular tissue ground tissue cortex+ epidermis. The main factor of the primary thickening process is the proliferation and the increase of pith cells. 在笋芽的初生增粗生长过程中,各组织的贡献率自大到小为:髓分生组织维管组织基本组织皮层+表皮,髓分生组织细胞的增殖与增大是竹笋进行初生增粗生长的主要因素。
The promeristem consisted of three groups of primitive cells which had the cytological characteristics of typical meristem cells and the primary meristem was composed of calyptrogens, dermatogen, periblems and pleromes. 原分生组织由3群原始细胞组成,其细胞具有典型分生组织细胞学特征;初生分生组织包括根冠原、表皮原、皮层原和中柱原。
