原分生组织

This study clearly showed that mosaic variation was caused by chlorophyll deficiency mutation of shoot tip histogen layer-Ⅱ;tissue and organs originated from the layer-Ⅱ couldn't synthetize chlorophyll,thus induced albino; the albino variation appeared yellow green mosaic because layer-Ⅱ was displaced by layer-Ⅲ partly.

研究表明，其变异原因是由于茎尖分生组织的L -Ⅱ组织原层发生失绿突变，致使其衍生的组织和器官不能合成叶绿素，从而形成白化现象；又由于L -Ⅱ与L -Ⅲ组织原层层间发生部分代换，致使白化突变呈黄绿镶嵌的花斑。

Furthermore, each developmental phase showed several different phases, these included inflorescence 0 phase, inflorescence Ⅰ phase, inflorescence Ⅱ phase; spikelet Ⅰ phase, spikelet Ⅱ phase, spikelet Ⅲ phase; palea primordium phase, lodicule primordium phase, stamen primordium phase and carpel primordium phase.

在这3个大的发育时期，又根据每一发育时期中的原基分生组织生长发育的程度及先后顺序分别又可分为：花序0期、花序1期、花序Ⅱ期；小穗期Ⅰ期、小穗Ⅱ期、小穗Ⅲ期；内稃原基分化期、浆片原基分化期、雄蕊原基分化期、心皮原基分化期。

At the reproductive stage, RA68 was expressed in the inflorescence meristem, the tip of rachis branch, spikelet primordia, macrospore sac and pollen grains.

原位杂交分析结果表明：在幼苗期RA68主要在幼芽胚芽鞘的内外层细胞和幼叶原基的表层细胞中表达；转入生殖生长期后，在花序分生组织、枝梗原基顶端、花器官原基、大孢子囊和花粉粒中表达。

The outer layer of apical meristem, from which the epidermis is formed.

表皮原顶端分生组织的外层，表皮就是从这里形成的

Cells of the procambium and ground meristem are more vacuolated than those of the protoderm.

原形成层和基本分生组织的细胞比原表皮层细胞更加液泡化。

LjFLO has a possible role in maintaining the marginal meristem of compound leaf primordia.

LjFLO的功能可能与复叶原基边缘分生组织的维持相关。

With tile ovary maturing, the orifice was narrowed because of tile ovary growth at last fused completely. The gynoecium is composed of a single carpel.(1) In tile series developmental sections of ovary, the ovular primordium was initiated on the adaxial meristem when tile mouth of ovary was formed.

子房由1枚心皮构成；(4)从子房发育过程的切片看，该植物的胚珠是在子房发生后不久发生的，子房上的圆孔形成时，从近轴侧的分生组织发生胚珠原基，由胚珠原基分化出珠被与珠心。

In root meristem it is also called periblem.

根部分生组织也称为皮层原。

Leaf buttress A leaf primordium, appearing as a protuberance on the side of the stem apex, produced by periclinal division of the tunica and corpus, and associated with a procambium.

叶原座：顶端分生组织上的侧生突起发育成叶的原基，与原形成层有关。

WOX3 specifies the cell fate at the margins of cotyledonary primordia and regulates the rate of cell division in the margins of meristem in Arabidopsis.

阿拉伯芥的PRS/WOX3基因参与子叶原基边缘细胞专一性的决定，及调控分生组织边缘细胞分裂的速度。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
