摘要
研究了播期、密度对甘蓝型黄籽油菜粒色及其他主要品质性状的影响。结果表明,播期与黄籽油菜粒色变化关系密切,随着播期的推迟,甘蓝型黄籽油菜黄籽度先升高后降低。正常播期范围内,早播有利于提高种子含油量。随播期的推迟,甘蓝型黄籽油菜的胚蛋白质含量却呈上升趋势。随着种植密度的加大,甘蓝型黄籽油菜皮壳率逐渐增加而皮壳含油量和皮壳纤维素含量则呈降低的趋势。
Sowing date was shown to have a significant effect on the yellow - seededness of the yellow - seeded rapeseed （ Brassica napus L. ）. As sowing was postponed, yellow - seededness increased steadily to a certain point, followed by a decline. Within the range of normal sowing dates, earlier sowing favored the improvement of oil content of the seed. The protein eontent of the embryo tended to rise with postponing of sowing. With the increase in planting density, the rate of seed coat increased gradually while the oil and crude protein of the hull decreased.
