Histogen theory A theory, proposed by Hanstein, in which the apical meristem is considered to consist of three main zones, the dermatogen, periblem, and plerome, which differentiate into the epidermis, cortex, and stele respectively.

组织原学说：是由 Hanstein 提出的理论，认为顶端分生组织是由三个主要区域组成，表皮原、皮层原和中柱原，随后它们各自分化为表皮，皮层和中柱。

The development of root could he divided into four stages, promeristem, primary meristem, primary structure and secondary growth stage.

结果表明，黄芩根的发育可分为原分生组织、初生分生组织、初生结构和次生生长等4个阶段。

The results showed that the number of chromosome, which was from the cultured seedlings of meristem tip and the rank seedlings of meristem tip, was not altered, both the number were 2n=16,the hereditary stability of callus and regeneration plant was poor; and the variation percentage of chromosome in callus was 43.4%, among which haploid accounted for 6.7%, triploid accounted for 2.5%,tetraploid accounted for 10%,pentaploid accounted for 4.2%,hexaploid accounted for 3.3%,septuploid accounted for 4.2%,octoploid accounted for 3.3%,dysploid accounted for 9.2%;the chromosome variation percentage of differentiation seedlings derived from callus was11.7%,among which haploid was 6.7%,triploid accounted for 1.7%,tetraploid was 3.3%.

结果表明，茎尖分生组织培养的幼苗及丛生苗遗传稳定，其染色体未发生倍性变异，均为2n=16；愈伤组织及其再生苗遗传稳定性较差，愈伤组织染色体数变异率为43.4%，其中单倍体占6.7%、三倍体占2.5%、四倍体占10%、五倍体占4.2%、六倍体占3.3%、七倍体占4.2%、八倍体占3.3%、非整倍体占9.2%；愈伤组织分化苗染色体变异率为11.7%，其中单倍体占6.7%，三倍体占1.7%，四倍体占3.3%。

Intrafascicular CAMBIUM between xylem and phloem. Apical initials are rarely single cells except in certain lower plants, and initiate more than one structure, e.g.

这种细胞存在于根和芽的顶端分生组织以及在原来分裂组织基础上形成的侧生分生组织，如位于木质部和韧皮部之间的束中形成层。

Primary tissue Plant tissue that is derived solely from meristems present in the embryo and their derivatives.

初生组织：指直接来源于胚的分生组织及其衍生细胞分裂活动所形成的植物组织。

And GmAG was observed a little at reversed shoot tips, which indicated GmAG had a characteristic of transition from shoot apical termination to floral meristems.

受长日照影响的茎顶，在发生逆转的顶芽上有少量的GmAG的表达，证明GmAG有决定分生组织向花分生组织转变的特性。

The expression pattern of Triae;CYCD2;1 was analyzed by RNA blot hybridization and in situ hybridization , the results revealed that Triae;CYCD2;1 expression is associated with the proliferation tissues, particularly in meristems and leaf primordia.

组织切片结果显示35S：：Triae；CYCD2；1转基因拟南芥叶片的栅栏组织和海绵组织分化不明显，多数细胞排列已不规则，茎表皮下多层细胞明显变短，苗端分生组织明显增大且具有较多未分化的小细胞。
