- 摘要:
- 为研究大豆倒伏性对耐密性及产量的相关性，以100份大豆资源为试验材料，通过不同密度及不同结荚习性类群分析，揭示大豆倒伏率与产量的相关性。结果表明：不同密度及不同结荚习性类群间大豆倒伏性与产量差异均达到显著或极显著水平，倒伏性与产量呈显著或极显著负相关，在高密度下倒伏性与产量相关性较强。同一密度不同结荚习性类群间倒伏性与产量相关性差异不大，同一结荚习性不同密度间倒伏性与产量相关性差异较大，说明密度对倒伏性及产量具有较大影响。
- Abstract:
- In order to know the correlation between the lodging and density tolerance and yield,one hundred soybean germplasm resources were used to divide different groups of density and podding-habits and analyze the interactive relationship between lodging and yield. The results showed there were significant or extremely significant correlation between the lodging and yield under different density and podding-habits groups. The correlation of lodging and yield was negative extremely significant and had the higher correlation under high density. There were small change of the correlation between lodging and yield under the same density and different podding-habits groups . There were large change of the correlation between lodging and yield under the same podding-habits groups and different density. So the effects of density on lodging and yield were large.
