摘要： 甘蓝型油菜作为主要食用油菜在中国长江流域广泛种植,由于菜籽饼粕中硫甙的降解产物有毒,油菜育种家们致力于降低油菜籽中硫甙含量。而油菜叶片中硫甙含量和组成与油菜的抗病性和菜用油菜的口感相关,文献报道油菜中吲哚类硫甙降解产物具有抗癌效应。目前菜-油兼用型甘蓝型油菜新品种在长江中下游普遍种植。油菜高硫甙叶片低硫甙种子是油菜育种家育种的理想目标。本文采用高效液相色谱法分析了甘蓝型油菜杂交品种及其亲本叶片硫甙含量和组分及其不同生育期叶片硫甙变化规律。研究结果表明,高硫甙油菜中油821叶片硫甙苗期含量最高,自苗期持续下降;而双低油菜材料中硫甙含量从越冬到现蕾逐渐升高,苔期降低,初花期又升高。双高油菜和双低油...
