摘要
选用普通玉米SC-704(对照)和3个不同株型高油玉米为试验材料,分别采用5种不同的种植密度,探讨群体密度对高油玉米品质的影响。研究结果表明,同一品种不同密度处理随密度的增加子粒含油率、蛋白质和淀粉含量呈下降趋势。高油115和高油298子粒含油率在授粉后20～30d达到最高,高油XY-1在授粉后50d达到最高;高油298和高油XY-1子粒蛋白质含量授粉后40d达到峰值,高油115子粒蛋白质含量成熟期蛋白质含量达到最大值。高油115和高油298子粒淀粉含量积累在授粉后40d,高油XY-1为授粉后50d。
Based on the experiment with three different plant-types of high oil varieties and ordinary corn variety SC-704 (comparison) respectively under five different densities was studied. The results showed that the same variety of different densities dealt with the increase of grain density, oil content, protein and starch content declined. The rate of Gaoyou115 and Gaoyou298 seeds reached the highest in 20-30 days after pollination, GaoyouXY-1 in the highest 50 days after pollination, Gaoyou298 and GaoyouXY-1 p...
