| 摘 要： | 通过对高温条件下3个芥蓝品种菜薹色素及其相关因素研究,结果表明:芥蓝菜薹的叶绿素、花青苷和类黄酮含量尖叶夏芥蓝均为最高,荷塘芥蓝次之,中花芥蓝最低。尖叶夏的有机酸含量最高,中花次之,荷塘最低。花青苷含量较高的品种,其苯丙氨酸解氨酶(PAL)活性也比较高。芥蓝菜薹表皮色泽是叶绿素、类黄酮和花青苷等色素的综合表现,并受表皮酸碱性的影响。

| Abstract: | The stalk pigments and correlate factors in three Chinese kale (Brassica alboglabra Bailey) cultivars under high temperature were studied. The results showed that the contents of chlorophyll, anthocyanin and flavonoid were highest in Jianyexia,followed by Hetang. The order of contents of organic acid was Jianyexia > Zhonghua > Hetang. There were higher phenylalanine ammonialyase (PAL) activities in cultivar which had higher anthocyanin content. The stalk color of Chinese kale was syntheses of chlorophyll, anthocyanin and flavonoid, and affected by acidity in stalk epidermis. |
