【摘要】 供试材料甘蓝型黄籽油菜杂交种"渝黄1号"分别种植在7个不同经纬度的生态点,研究了地理位置对甘蓝型黄籽油菜粒色的影响。结果表明,纬度与甘蓝型黄籽油菜粒色的变化有一定关系,随着纬度的升高,甘蓝型黄籽油菜黄籽度逐渐增加,粒色变淡,表明高纬度可能不利于种皮色素的形成。更多还原

【Abstract】 The yellow-seeded rape ( Brassica napus L.) hybrid Yuhuang No1 was grown at 7 ecological sites differing in longitude and latitude. The color of seedcoat seemed to be associated with latitude. Seedcoat color became lighter in tint as the latitude of cultivation moved northward, suggesting that less pigment is synthesized in seedcoat in high latitude areas than in low latitude areas.更多还原
