| 摘 要： | 在5个播种密度下对燕麦的6个数量性状进行了研究。结果表明：不同播种密度下燕麦的单株分蘖数、穗粒重、穗粒数、单株地上生物量都存在极显著的差异，随播种密度的增加这几个性状均呈减少或下降的趋势；千粒重和株高这2个性状比较稳定，不随播种密度的改变而发生相依变化。

| Abstract: | Six quantitative characters of oat were measured under 5 seeding densities. The results indicated that there were significant differences ( p <0.05) in tiller number per plant, grain weight and number per ear, and biomass aboveground per plant, but 1000 grain weight and plant height were relatively stable. |
