摘要
羊草Leymus chinensis结实粒数的多少是评价羊草有性繁殖的一个重要指标。根据羊草单穗结实数与小花数间极显著正相关的研究结果,提出了以选育单穗小花数多的大穗型羊草品种增加种子产量的思路。大穗型羊草品种具有枝繁叶茂的形态特征。
The number of seed-setting ot Leymus chznenszs is an lmportant index duetion. On the basis of the achievement in research that the number of seed-setting per head is direetively propostional to the number of flowers , this article proloses raising its seed yield through selecting big ear type L. chinensis with a larger number of flowers per head. Big ear type L. chinensis has rather dense branches and leaves.
