| 摘 要： | 为确定辽单565在辽宁地区制种的最佳种植密度，采用对比试验的方法，研究不同密度对种子农艺性状及种子活力的影响。试验结果表明：不同制种密度对农艺性状及种子活力影响不显著；4500株／667m^2密度下的发芽率最高，种子活力水平和冷发芽结果也较高。为辽单565制种的最佳密度。

| Abstract: | In order to determine the best planting density for Liaodan 565 seed production in Liaoning, the method of contrast experiment was adopted to study the effect of different densities on the agronomic characters and seed vigor. The test results show that the effect of different seed density on the agronomic characters and seed vigor is not significant; and the the best density for Liaodan 565 seed production is 4 500 strains /667 m^2 as it has the highest germination rate, and higher level of seed vigor and higher cold germination results. |

| Keywords: | maize seed production Liaodan 565 seed vigor planting density germination rate |
