The results showed that the two parents Elymus canadensis and E. sibiricus had relatively closer relationships.

旨在用分子标记方法探索亲本加拿大披碱草与老芒麦及其远缘杂种后代的遗传关系，为后期育种提供理论依据。

Elymus dahuricus Turcz seeds were separately treated with different concentrations of NaCl and Na2CO3 for 7 days to observe the germination.

RAPD Analysis of Elymus canadensis, E. sibiricus and Their Hybrid F1, F2

篇名 加拿大披碱草和老芒麦及其杂种Fl， F2的RAPD分析

The growth parameters of 20 accessions of Elymus spp. at early seedling stage were measured under various salt stress at 0, 0.4%, 0.6%, 0.8% and 1.0% NaCl in the soil, and the accessions were sorted out using the method of polar ordination.

设置对照(0)、0.4%、0.6%、0.8%和1.0%等5个土壤盐浓度水平，对披碱草属20份野生种质材料的苗期生长参数进行测定，在此基础上采用极差分类进行种质材料的耐盐性排序。

Result show that in the early phase of Caragana korshinskii and Elymus dahuricus, there is three distinct layer in 0~500cm: As it grow and root stretch deeper, more and soil water is needed, in the forth year dry layer appear between 120~220cm, depth 100cm.

结果表明，在水平阶营造柠条和披碱草，在生长初期0~500cm土层含水量可分为3个明显的层次；在生长的第4年随著灌草根系深扎，土壤水分过耗，出现明显的乾土层，分布深度在120~200cm，厚度为100cm。

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 the natural improved grassland with uncultured and resowed,the sorts of grass increased 5～8 varieties,and the height of elymus dahuricus and the sedge respectively was higher than that of the control area for...

在免耕补播改良天然草地方面，草地植被种类增加5～8种，披碱草高度较对照区高出18cm，苔草高出4cm，其总盖度较对照区高出近20%，而施肥试验草层高度较对照区增加了1.5cm，其盖度由55%增加至90%，增幅为35%。

The main agronomic traits and cytology of BC1F2,BC1F3,BC1F4 between Elymus dahuricus, Hordeum brevisubulatum were studied.

研究了披碱草与野大麦BC1F2、BC1F3、BC1F4代的主要农艺及分子细胞遗传学特性。

Comparative analysis of some rbcL gene cDNA sequences between wheat and other species were also carried out, the result suggested that the rbcL gene was highly conserved in examined species, common wheat is more closer related with Hordeum, Psathyrostachys, Leymus, Elymus than with Oryza and Zea.

进一步比较分析了在相关物种中rbcL基因的cDNA序列，结果显示，rbcL基因的编码区在不同属的物种间高度保守，并从分子水平表明小麦与大麦、新麦草、赖草、披碱草属等的亲源关系比与水稻、玉米等的近。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
