查询词典 generative cell

A dual cell system was used to study the relationship between time and electric quantity, dissolved Cu(superscript 2+), Fe(superscript 2+) and Mn(superscript 2+) ratio in the process of electro-generative simultaneous leaching and bio-electro-generative simultaneous leaching.

采用双电池体系研究发电浸出过程和生物发电浸出过程中放电量、Fe(上标 2+)和Mn(上标 2+)浸出率与时间的关系。

The generative cell contains a few plastids immediately after the microspore mitosis in L.

在生殖细胞的发育过程中，线粒体的DNA也很快降解。

The ultrastructure characters of pollen grain in Brassica napus are:1There are vacuoles in cytoplasm but no starch grain in uniceelluar pollengrain.2The veget- ative nucleus of bicellular pollen grain is generally spheroidal;while the generative cell is spinde-shaped,with a big nucleus,thin layer of cytoplasmand few cell orgens,no cell wall.3In three-celled pollen grain the sperm cell is separated from the cytoplasm of vegetative cell by two layers of plasmic membrances.

Brassica napus的花粉粒，在不同发育时期超微结构的特征如下：1单胞花粉粒有一个球形的细胞核和明显的核仁，细胞质内出现液泡，缺少典型的淀粉粒。2双胞花粉粒的营养核多为球形。生殖细胞纺锤形，无细胞壁，细胞核比例大，细胞质呈薄层，细胞器少。3三胞花粉粒有一个裂片状的营养核和两个纺锤形的精细胞，精细胞无壁，以两层质膜与营养细胞的细胞质相隔。

Generative nuclei The two gametic nuclei formed by the division of the generative cell in the pollen tube of angiosperms.

雄原核：在被子植物花粉管中的生殖细胞分裂成两个配子的核。

It is proved by ultrastructural observations that few plastids and abundednt mitochondria were ever presenting in the generative cell of Pisum sativum from its formation to maturation.

在豌豆中证明了生殖细胞自形成直至成熟花粉时，始终存在少量质体和较多的线粒体。

It was proved by ultrastructural observations that few plastids and abundent mitochondria were ever present in the generative cell of Pisum sativum L.

About a year after pollination, the generative cell of the four-celled male gametophyte undergoes division, giving rise to two kinds of cells—a sterile cell and a spermatogenous cell.

在授粉后大约一年，四个中生殖细胞-细胞男性的配偶体接受区分，引起细胞的二个类型-一个不毛的细胞和一个 spermatogenous 细胞。

It is showed that MG132 significantly reduced the germination rate and tube growth. Furthermore, MG132 treatment lead to vacuolization occurred both in tube cytoplasm and generative cell. While DMSO and non-proteasome inhibitor E-64 do not have similar effects. FTIR analysis revealed that MG132 treatment markedly reduced the contents of wall-bound proteins and pectin at the apex of tube.

结果表明：MG132显著抑制青扦花粉萌发和花粉管生长，并导致花粉管形态异常，主要表现为花粉管亚顶端出现液泡化，并且液泡随着培养时间的延长而扩大到整个花粉管，花粉管濒临死亡；而DMSO以及非蛋白酶体抑制剂E-64不产生类似结果；半薄切片结果表明，MG132处理后不仅花粉管细胞质发生液泡化，生殖细胞也发生液泡化；FTIR分析进一步表明，MG132处理后，花粉管顶端的细胞壁蛋白和果胶质含量大幅度下降。

During two-celled pollen grain stage, they were accumulated on the wall of the generative cell. After the generative cell came into the vegetative cell, ppts largely disappeared.

二胞花粉刚形成的生殖细胞表面呈现大量的ATPase反应颗粒，当生殖细胞脱离花粉内壁移入营养细胞，ATPase反应颗粒基本消失。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
