对嫁接在“八棱海棠”上的“鲁加”系列(1~6号)苹果果实生长发育期间总酚、类黄酮和果皮色素含量的变化进行了研究。结果表明:从盛花期后50d至果实成熟,“鲁加”苹果的果皮和果肉内的总酚、类黄酮含量均呈逐渐下降趋势;果皮总酚和类黄酮含量变化趋势相似,多在盛花后50~70d下降幅度较大;果肉总酚和类黄酮含量变化趋势相似,多在盛花后50~90d下降幅度较大。其中,“鲁加1号”苹果果皮和果肉的总酚和类黄酮含量变化趋势平缓;在盛花期后50~70d,果皮花青苷呈下降趋势;在盛花期后70d至果实成熟呈上升趋势,“鲁加1号”和“鲁加4号”上升幅度较大。
The changes of pigment contents of total phenols, flavonoids and pericarp during the growth and development of “Lugar” series (No.1 ~ 6) grafted on “Bailong Begonia” were studied. The results showed that the content of total phenols and flavonoids in pericarp and pulp decreased gradually from the 50th day after flowering to maturity. The contents of total phenols and flavonoids in pericarp were similar The content of total phenols and flavonoids in flesh tended to decrease after 50 ~ Among them, the content of total phenols and flavonoids in apple peel and pulp apparently changed slowly in “Lu Jia No.1” apple; Anthocyanin in peel decreased gradually from 50 days to 70 days after full bloom; Up trend, “Luga 1 ” and “Luga 4 ” increased by a large margin.
