An artificial amphiploid RSP (2n=42, AABBDD) obtained by tetraploid landrace Ailanmai (Triticum turgidum L., 2n=28, AABB) and Aegilops tauschii (DD, 2n=14) expressed high tolerance to preharvest sprouting which derived from Aegilops tauschii.

The results indicated that both WUE and NUE increased during the evolution process from diploid to hexaploid.

结果表明，小麦在从二倍体→六倍体的长期进化过程中，WUE和NUE均表现出增加的趋势。

Since 2000, sales of heavy-duty trucks have raised six fold while car sales have risen eightfold.

The distribution of hybrid chlorosis Ch1 gene and the T-type cytoplasm fertility restoring genes in Chinese endemic wheats were studied using the testors QA1104 (T-type cytoplasm sterile line, with hybrid chlorosis Ch2 gene) and Khapli emmer (with hybrid chlorosis Ch1 gene).

本研究以T型不育系QA1104（具有杂种黄化基因Ch2）和Khapli（具有杂种黄化基因Ch1）为测验种，对中国特有小麦等六倍体小麦类型和一些四倍体小麦类型中的T型胞质育性恢复基因和杂种黄化Ch1基因的分布进行了研究。

They have now multiplied sixfold since 2002, compared with the fourfold increase of the 1973 and 1974 "oil shock" that ended the world's long postwar boom.

他们现在成倍增加六倍，自2002年以来，相对於增加了四倍的1973年和1974年"石油冲击"，结束了世界的长期战后繁荣。

As catalyst, the tungstosilicic and phosphato-tungstic acids have similar catalytic activities which are six times more than that of sulfuric acid in the same reactive conditions.

钨硅酸和磷钨酸具有相似的活性活性，在同样条件下，其速度常数均为硫酸的六倍，其选择性为硫酸的3倍。

The characteristics of the resting nuclei and the prophase chromosomes of all the tetraploids and hexaploids were quite similar to each other.

所有四倍体和六倍体的体细胞间期核特征和前期染色体形态特征基本相似。

"Wheats are called diploids when they have seven chromosomes, tetraploids when they have fourteen , and hexaploids when they have twenty-one."

其性细胞具有7条染色体的小麦称为二倍体；具有14条染色体的称为四倍体；具有21条的称为六倍体。

The tetraploids of C.reticulata from the localities with the altitude of over 1800 m were gross-morphologically similar to the hexaploids, but those growing between 1100 ～1800 m were different to some extent from the hexaploids.

中海拔(1800m)以上的四倍体的云南山茶花外部形态特征与六倍体类型比较相似，而低海拔(1100～1800 m)的四倍体类型的外部形态特征则有些不同，但核形态结构是比较相似的。

In grain-filling stage, the qP values of evolutionary wheats decreased under water stress, while Shan253 and Changwu134 hadn't decreased, indicated that the effect of water stress on the re-oxidation in Q-A of modern wheat was slight, while before this stage, the electron transport from PSⅡto QA restrained by water stress was main factor of photosynthesis non-stomata limitation to modern wheat; The qNP values of hexaploid were higher than diploid and tetraploid wheat, indicated that the ability of using light energy

随小麦由二倍体向四倍体、六倍体及现代小麦进化，表观电子传递速率有增大趋势，其受水分胁迫影响的程度在花前期有加剧趋势，花前期栽培一粒、栽培二粒、普通小麦、陕253和长武134这五种小麦在水分胁迫下表观量子产额的降幅分别为5%、7.47%、14.29%、33.3%和53.49%，光饱和Pn的降幅分别为8.8%、26.14%、23.25%、44.22%和51.29%，光饱和点整体上也是下降的，且这三个指标的降幅随进化程度提高有增大趋势，表明小麦在进化过程中能量转换系统受水分胁迫影响的程度加剧；而在水分胁迫下，小麦的羧化效率和RuBP再生速率也均下降，下降的程
