查询词典 Elymus

Love was the maternal donor of the polyploid Elymus; the "Y" genome existed in the StY-genome Elymus may be differentiated from the St genome, i.e., the autopolyploid StSt-genome species probably experienced genomic differentiation within a species after autopolyploidy, leading to the significant genomic change and resulting the StY-genome allotetraploids; the StY genome species distributed in the Central Asia with a high level of genetic diversity radiated to the Western and Eastern Asia, under the environmental selection and other factors, and only a few species spread to the western Asia and most species have remained in the Central and eastern Asia.

3分子证据表明在StY基因组的物种之间有明显的地理分化，中亚可能是StY基因组披碱草属植物的分化中心，并在此基础上，StY基因组的披碱草属植物向东亚和西亚进行了快速的辐射，形成了现代StY基因组物种的分布格局；多次杂交、迁移和分化是StY基因组的披碱草属植物进化的主要动力。(4)拟鹅观草属物种可能是所有披碱草属植物的母本供体。

Then using PAUP 4.0 10b software, Elymus trachycaulus and Pseudoroegneria spicata and Carex nigra as outgroups respectively, 3 striction consensus trees were constructed.

分别以禾本科早熟禾亚科的两个种：Elymus trachycaulus和Pseudoroegneria spicata和莎草科的一个种：Carex nigra为外类群，使用PAUP 4.010b软件，构建了3个最简约的系统发育树。

In this paper, a 2-year field manipulative experiment was conducted to study the effects of clipping (stubbled 1 cm, stubbled 3 cm, and unclipped), fertilizing, and watering on the compensatory growth of Elymus natans . The compensatory height, specific leaf area, net photosynthesis rate, and relative growth rate were measured, aimed to approach the compensatory mechanism of the species.

通过为期2年的野外控制实验，研究了刈割高度（留茬1 cm、3 cm及不刈割）、施肥和浇水处理对垂穗披碱草补偿生长的影响，并结合对各处理分株密度、比叶面积、净光合速率和相对生长率的变化研究，探讨了其补偿生长机制。

Genetic differentiation between and within five eco-geographical groups of Elymus nutans was estimated by Shannon's diversity index, which shown that 42.94% genetic variance existed within group, and 50.76% genetic variance was among groups.

基于Shannon 多样性指数估算了5个垂穗披碱草地理类群内和类群间的遗传分化，发现类群内遗传变异占总变异的42.94 %，而类群间的遗传变异占总变异的57.06 %。

Acid polyacrylamide gel electrophoresis was employed to detect the gliadin genetic diversity among fifty-four wild accessions of Elymus sibiricus L.

采用酸性聚丙烯酰胺凝胶电泳对采集自青藏高原的54份野生老芒麦（Elymus sibiricus L。

In order to compare the usefulness of ISSRs and SSRs in Elymus species, 33 ISSR primers and 137 wheat SSR primer pairs were employed to detect 12 species of Elymus in this study.

为了比较ISSR和SSR标记在披碱草属

In this work, we used the sequences of nuclear genes (ITS, Adh2, Adh3 and Waxy) and cpDNA (trnL-F and matK) to explore the origin of Elymus species and the Y genome, and to reveal the mechanism of the geographical differentiation of the StY-genome Elymus species.

本文通过核基因ITS、Adh和Waxy基因以及叶绿体基因trnL-F和marK的序列分析了披碱草属相关二倍体种的系统发育关系和披碱草属植物的起源。

The company has a deep knowledge, over the years engaged in teaching, research, production, technology services, middle-aged and young scientists for many years in Qinghai grass seed bred breeding Poa cold Qinghai, Qinghai Chinese fescue, Tongde Elymus wheat, grazing Green on the 1st and Qinghai Elymus sibiricus Elymus Mans short five new varieties.

公司拥有一支造诣精深，多年从事教学、科研、生产、科技服务的中青年科学家队伍，多年来在青海省牧草良种繁殖场选育出青海冷地早熟禾、青海中华羊茅、同德老芒麦、青牧1号老芒麦和青海短芒披碱草5个新品种。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
