查询词典 hexaploid

Einkorn is the valuable genetic resource for improvement of resistance in hexaploid wheat(Triticum aestivum L.).

一粒小麦是普通小麦抗性改良的宝贵资源。

The result suggested that different genomes had different genetic speed or stability during evolution.3 The similarities co-efficiency between wild emmer and hexaploid synthetic was higher than that between wild emmer and common wheat. So that crossing among species is not a simple combination of genomes, but involve introgression of chromosomes, and the evolution made by this action was bigger than that made by environment.4 According to the results of salt tolerance identification, the salt tolerance of wild emmer is lower than that of common wheat in the whole.

野生二粒小麦与普通小麦之间的遗传相似系数稍高于野生二粒小麦与其与节节麦合成的双二倍体的遗传相似系数，说明物种之间的杂交并不仅仅是染色体组简单的合并，其中包括复杂的染色体组本身的一些特性以及染色体之间的互渗且这种作用远大于环境作用所引起的变化。

The genetic variation of chloroplast genome in spelt and T. tibetanum was more abundant than that in common wheat and there were closer genetic relationships between common wheat and T. petropavlavskyi and between hexaploid wheat and emmer.

结论］斯卑尔脱小麦和西藏半野生小麦等群体内的叶绿体遗传变异比普通小麦更丰富；野生二粒小麦与六倍体小麦以及新疆稻麦与普通小麦之间具有很近的亲缘关系，为不同小麦种的遗传差异提供依据。

The results showed that diploid and tetraploid had higher root activity, flagleaf soluble protein content, SOD and CAT activity before anthesis. However, the rootactivity, flag leaf soluble protein content, SOD and CAT activity of diploid and tetraploiddeclined more quickly and became lower than those of hexaploid species from 15 days afteranthesis. While MDA content increased more quickly and became higher than those ofhexaploid species from 5 days after anthesis. Correlation analysis showed that delaying the flag leaf senescence can promoted transfer of nitrogen and dry matter, increasedaccumulation of nitrogen and dry matter after anthesis, enhanced grain and protein yield.

结果表明，与普通小麦和小黑麦相比，二倍体和四倍体材料开花以前具有比较高的根系活力、可溶性蛋白含量、SOD和CAT活性；开花以后，根系活力、旗叶可溶性蛋白含量、SOD和CAT活性快速下降，MDA含量快速上升，衰老加快；相关分析表明，延缓小麦旗叶衰老进程，可以促进花后氮素和干物质运转，增加花后氮素和干物质积累，提高籽粒产量和籽粒氮素积累量。

However, as a hexaploid species, this study was hampered by the complexity of the wheat genome.

然而，普通小麦作为异源六倍体物种，其基因组的复杂性为功能基因分子标记的开发带来了极大的困难，因此研究在普通小麦中开发SNP标记同样也具有重要的理论意义。

Comparison with hexaploid bread wheat, there were one or two different chromosomes in Xinjiang rice wheat.

细胞学研究的结果认为新疆稻麦有1～2条染色体与普通小麦不同。

The results provide a theoretical basis for transferring fine genes from Hexaploid Triticale to wheat.

研究结果为将六倍体小黑麦的优良基因导入到普通小麦中提供了理论依据。

The results indicated that synthetic hexaploid wheat Syn-CD780 could be used as an useful source for improving wheat quality.

Syn-CD780在小麦品质改良上有一定的潜在利用价值。

The goal of this study is to analyze the genetic diversity of chloroplast genome among hexaploid wheat populations and their relatives.

［目的］系统分析不同小麦种的细胞质基因组遗传差异，用以发掘和利用新的小麦种质资源。

But in hexaploid triticale x common wheat, they rely on the chromosome breakage and recombination.

而在其反交中，外源基因的导入则更多依赖于染色体的断裂与拼接。

The work of this paper is as follows: 1. Looking back the progressing history of the linear motor, introducing the features of the elevator driven by linear induction motor, radicating the topic of this paper "the digital frequency variable control of the elevator bi-side direct driven by linear induction motor". The research of this paper covers the conventional VVVF control, space vector based VVVF control, vector control and DTC.
