初生分生组织

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。

Primary meristem of stem is composed of protoderm , procambium and ground meristem .

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。

The development of leaf includes original meristem , primary meristem and mature structure of three stages .

初生分生组织由原表皮、基本分生组织和原形成层组成。初生分生组织的衍生细胞分化形成茎的初生结构，包括表皮、皮层、维管束、髓和髓射线。

The primary structure consisted of epidermis , cortex , vascular system , pith and pith ray .

Leaves could be divided into three stages : promeristem , primary meristem and mature structure . The leaf of Bupleurum chinense DC .

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。

The primary meristem of the root tip may be extended a section of distance below the elongation region . ( biology ) produced by metamorphosis .

牛膝根及茎的发育均包括原分生组织、初生分生组织、初生生长、次生生长和三生生长5个发育阶段。

The development of A. bidentata root and stem was divided into five developmental stages , which were promeristem , primary meristem , primary structure , secondary structure and tertiary 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。

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 .

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。

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 .

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。

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 .

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 the primary meristem of stem and the early stage of stem 's primary structure , the essential oil was mainly distributed in glandular hairs ;

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。

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 .

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。

Cell divisions were diffused almost in the whole axis , and no primary thickening meristem occured .

从第3～5幼叶基部，初生增粗分生组织细胞层数逐渐增加，细胞分裂能力强，分化程度低；

From the base of the 3rd young leaf to that of the 5th one , there was a increasing tendency in cell files of the PTM , and the cells of the PTM rapidly divided and less differentiated .
