不同播种密度对燕麦几个数量性状的影响

Effects of seeding density on quantitative characters of oat

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 。

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.
