The variation and differentiation of Leymus Chinensis population were systemically studied. The results showed that there were great difference in leaf color, spike, heading rate and leaf width in Leymus Chinensis population.

本实验对羊草种内变异与分化进行了系统的研究，发现羊草种内变异多样性较高，在叶色、穗型、穗色、抽穗率高低和叶片的宽窄等方面都存在着明显的变异。

The descent of the spike length and the grain number per spike were main factors to induce reduction of output, the spike width and the weight per 100 grain were indirect factors to effect corn yield.

穗长、穗粒数的下降是影响产量的主要因素，穗粗、百粒重是影响产量的间接因素。

The correlation between the number of grain per spike and the width of the sword leaf was significant and larger than that between grain number and area of the sword leaf.

其中，剑叶宽与穗粒数呈极显著正相关，相关程度大小为宽>面积。
