摘　　要：为了明确种植密度对小豆产量等性状的影响,于2007年和2008年分别设置5个密度水平,在吉林省农业科学院作物育种研究所试验站进行田间试验。结果表明,在不同种植密度条件下,株高、百粒重的差异不显著,分枝数、主茎节数、单株荚数和单株产量有随着密度增大而减少的趋势。除了在最小密度10.5万株/hm2下产量有显著减少外,其他密度下的产量均没有显著差异。通径分析表明,单株产量对产量的直接贡献较大,其次是百粒重。In order to understand responses of adzuki bean to plant density,the study was carried out under five levels of plant density in both 2007 and 2008.The results showed that plant height and 100-seed weight had no significant difference under different plant densities,and number of branches,node number of main stem,number of pods per plant,and yield per plant had a decreasing trend with increasing plant density.The yield decreased significantly under the lowest plant density of 10.5×104 plants/hm2,and the yield had no significant difference under other plant densities.Path analysis indicated that yield per plant had a great direct contribution to the yield,followed by 100-seed weight.
