不同有色稻品种资源花色苷含量分析

Analysis of Anthocyanin Content in Different Variety Resources of Colored Rice

摘要: 为筛选高花色苷含量水稻种质资源，以124份有色稻为研究材料，用pH示差法测定不同有色稻品种中花色苷的含量。结果表明：不同品种有色稻中花色苷含量存在极显著差异。含量最高的3个材料都是黑米品种，其中黑米品种HY023含量最高，达到22.01 mg·hg^-1；红米品种HY102含量最低，为8.06 mg·hg^-1；124个有色稻品种花色苷含量的平均值为12.90 mg·hg^-1，花色苷含量较高（>19 mg·hg^-1）的品种只有2个。

Abstract: In order to screen the germplasm resources of rice with high content of anthocyanins, 124 varieties of colored rice were used as research materials, and the content of anthocyanins in different varieties of colored rice was determined by pH-differential method. The results showed that there were very significant differences in the content of anthocyanins in different varieties of colored rice. The three materials with the highest content were all the varieties of black rice, among which the black rice HY023 had the highest content, reaching 22.01 mg·hg^-1, while the red rice HY102 had the lowest content, reaching 8.06 mg·hg^-1. The mean content value of anthocyanins in 124 varieties of colored rice was 12.90 mg·hg^-1, and two varieties had higher content of anthocyanins (>19 mg·hg^-1).
