生殖

This is a form of APOMIXIS.

这是一种单性生殖。

The current state of knowledge on the molecular and genetic basis of apomixis is reviewed.

本文对植物无融合生殖遗传机理和分子机理的研究进展作了综述。

First,using apomixis to establish a new method of rapid breeding.

利用无融合生殖建立快速育种新方法。

Second,apomixis and polyploidization were used to search new breeding method.

利用无融合生殖和多倍体化探索育种新途径。

Further studies are necessary to clarify a taxonomy complicated by hybridization and apomixis.

需要进一步的研究验证一种通过杂交和无融合生殖折叠的分类法。

The species present in China are not clear-cut and are also variable within themselves due to polyploidy and apomixis.

存在于中国的本种不明确，由于polyploidy和无融合生殖在他们自己内也是易变的。

The information will be useful for the development of apomixis technology and therefore has important implications for crops breeding.

本研究结果可作为建立无融合生殖生物科技之本土基础资料，并提供禾草作物育种时选材之依据。

But utilization of apomixis in breeding procedure could significantly shorten time of selection and fix heterosis.

然而利用无融合生殖特性进行育种将可能大大缩短育种年限，固定杂种优势。

Studies on genes related to embryo and endosperm development are leading us to an extensive understanding of the mechanisms of seed development and apomixis at the molecular level, which will benefits the research for yield and quality improvement of plant seeds via genetic engineering.

对胚和胚乳发育相关基因的研究，可使人们在分子水平上解析种子发育和无融合生殖的分子机制，更有效地开展植物种子产量和品质改良的基因工程。

The rale of plants with 42 chromosomes was up to 49.3%. The va riation of chromosome may have a connection with apomixis.

杂种后代的体细胞染色体数目的变化一方面与远缘杂交有关，另一方面可能与无融合生殖具有一定的联系。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
