摘要:
通过对夏播4个不同熟期的油葵杂交种在5种不同种植密度条件下小区籽粒产量的分析，结果表明：不同熟期的油葵杂交种的产量潜力不同，在播期一致的情况下，参试杂交种籽粒产量平均效应的优劣顺序为F53>F51>F57>S40，生育期较长的杂交种F53的籽粒产量要明显高于生育期较短的F57，同时也高于生育期比其长的S40，略高于生育期较短的F51；种植密度是影响夏播油葵杂交种籽粒产量的重要因素之一，且不同熟期的油葵杂交种获得最高产量的最佳种植密度不同，早熟杂交种的最佳密度较大，晚熟杂交种的最佳种植密度较低。
Abstract:
A field experiment was carried out to study the effects of plant densities on grain yield of different growth period of oilseed sunflower hybrids in Shenyang in 2008．The experimental design was randomized complete block with 3 replications．The treatments were four sunflower hybrids and five planting densities．The results indicated that the potential of grain yield was change with different vegetation period sunflower hybrids．The grain yield in order was F53>F51>F57>S40 in the same sowing date．Plant density had significant effect on grain yield of sunflower hybrids．The different vegetation period sunflower hybrids obtain the highest yield with suitable density．Suitable densities of short vegetation period sunflower hybrid were more than the suitable densities of long vegetation period sunflower hybrid.
