稻米品质与淀粉酶和蛋白组分的关系研究进展

摘要

The improvement of rice quality has become the main trends in current rice breeding.Thus, high-grade rice cultivar selecting and rice quality research are the emphasis in rice breeding field at present and in the future .The thesis summarized the relationship between the variances of activity of α,β-amylase in rice seeds and the rice quality , and cor-relations between the variances of protein components in seeds and the quality of rice.The correlation between variances in quality among different rice cultivars and activity of α,β-amylase and protein components was discussed , and its signifi-cance and application in rice breeding was prospected.%水稻品质改良已成为当前育种工作的主要趋势，优质米品种选育和米质研究是当前及今后水稻育种的重点。综述了水稻种子α，β-淀粉酶活性的差异与稻米品质之间的关系，以及种子蛋白组分间的差异与稻米米质的相关性。探讨了水稻品种间品质差异与α，β-淀粉酶活性和蛋白组分的关系，并对其在育种中的意义及应用进行了展望。
