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。

An appreciable increase in SLA and RGR after defoliated was not enough to induce overcompensation in plant height. However, fertilizing could enhance the compensation ability, and promote the plant species tolerance against defoliation. Our results confirmed the improved limiting resource model.
因此，即使刈割后比叶面积和株高相对生长率显著增加，也不一定必然引起株高的超补偿；但施肥可显著提高垂穗披碱草的补偿能力，增加耐牧性，证实了改进后的限制资源模型的预测。

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 %。
