摘要
以8个不同来源的甘蓝型黄籽油菜基因型为材料,研究了不同密度和氮素水平下粒色及其他主要品质性状的变化。结果发现,施氮可使甘蓝型黄籽油菜黄籽度明显提高,但同时种子含油量有下降趋势;施氮后多数基因型的胚蛋白质含量均有不同程度的增加;密度对黄籽油菜粒色、种子含油量的影响因基因型而异;密度对胚蛋白质含量有负效应,即密度加大,胚蛋白质含量有降低趋势。
In a field experiment, 8 yellow-seeded rapeseed ( Brassica napus L. ) varieties of different origins were grown with different planting densities and supplied with N fertilizer at different rates. N application significantly increased the yellowness of the seeds but tended to decrease their oil content. Protein content in the embryos of the seeds increased, to different extents, in most genotypes studied due to N application. The effects of planting density on seed color and oil content varied with genotype, and planting density showed a negatiye effect on protein content in the embryos, i.e. protein content in the embryos decreased with increasing planting density.
