分裂子

The embryogenic cell first divided into multicellular proembryos,then globular embryoid,pearshaped embryoid,long embryoid,scutiform embryoid and mature embryoid.

胚性细胞继续分裂形成多细胞原胚，经球形胚、梨形胚、长形胚、子叶分化期到成熟胚，其发生的胚状体与单子叶合子胚形成具有相似的过程。

The temperature affects the sustained time of secondary sporogenous cell split, the sustained time of microspore mother cell, formation speed and regular of male gametophyte.

温度影响次生造孢细胞持续分裂的时间、小孢子母细胞的持续时间及雄配子体的形成速度和整齐度。

So why did your work on the discovery on Tau Lepton take so long to make the order division.

那么为什么你的工作就发现轻子头村采取如此长的时间来作出该命令分裂。

The female gametes with 21 chromosomes intended to be with stronger competitive ability for pollination. Successful backcross didn't depend on the unreduced female gametes from restitution division.

同时也证明，回交的成功并不取决于杂种F1通过重建分裂形成的未减数雌配子。

Chiasmata also help to hold homologs together until the start of anaphase, thus helping to ensure the correct distribution of chromosomes into the daughter nuclei.

交叉还可以使同源染色体始终在一起直到细胞减数分裂的后期，这样确保了染色体可以正确的进入子细胞。

Later, in your country for a variety of reasons to split the Democratic Republic of Vietnam and the Republic of Viet Nam, the Government of South Vietnam behind China's civil war, as well as the backing of the United States occupation of the islands, such as the reasons for the Che-hung-xiu Island, south of the island, Dun-sandbank, Jinghong Island, South Island and amboyna and sent troops stationed.

在后来贵国由于种种原因分裂为越南民主共和国以及越南共和国，南越政府利用中国内战以及背后美国撑腰等原因占领了南沙群岛的鸿庥岛、南子岛、敦谦沙洲、景宏岛、南威岛和安波沙洲，并派军驻守。

Pollen grain is just the carrier of the male gametes, which are two nuclei found within the grain.

因为子株是由母株的组织细胞进行有丝分裂而形成的。

Vulgaris and Beta M14 BAC clone 16-M11 and 26-L15 are florescence specific expression BAC of Beta M14, both BAC clone 16-M11 and 26-L15 were in situ hybridization to monosomic addition lines(2n=2x=18+1) M14 chromosomes, they were located on the long arm of corollinae chromosome 9. the dominant factor of BAC clone 16-M11 and 26-L15 appears to hemizygous, because no equivalent region has been found in sexual Beta.

选用这两个BAC克隆作为探针，对M14甜菜有丝分裂中期染色体组进行荧光原位杂交，结果发现，BAC克隆16-M11和26-L15定位于M14甜菜附加的一条白花甜菜9号染色体上，有性栽培甜菜染色体上没有出现信号，两个BAC克隆在M14甜菜中呈半合子状态，遗传行为象单价显性基因，是白花甜菜9号染色体特异的。

Advancing wavefields by the degenerate migrators is actually a linear interpolation between two splitstep terms in the wavenumber domain.

退化的Fourier偏移算子通过在两个分裂步项之间作波数域线性插值来实现波场延拓，每延拓一层需要比常规的SSF地震偏移方法多一次快速Fourier变换。

The computationally efficient degenerate migrators extend the splitstep Fourier method to steeper propagation angles in largecontrast media at the cost of one more Fourier transform for each extrapolation step.

这种退化偏移算子只用快速Fourier变换进行波场延拓，将常规的Fourier分裂步地震偏移方法推广适应强速度横向变化介质和大角度传播波场。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。

Male cats normally do not need aftercare with the exception of the night after the anesthetic.

男猫通常不需要善后除了晚上的麻醉。
