摘　　要：选用粳稻品种东优9901和长粒香,研究不同收获时期对稻米味度值与RVA谱特性的影响。结果表明：不同收获期处理间的味度值和粘滞峰消减值没有显著差异;但整精米率、下降粘度和最高粘度均存在显著或极显著的差异,东优9901在灌浆35～40 d时RVA谱特性最佳,而长粒香在灌浆35～45 d时RVA谱特性最好。Two Japonica rice varieties--Dongyou9901 and Changlixiang--were studied to reveal the effect of different harvest date on rice grain taste meter value and RVA profile. The results showed that among the different harvest date treatments there was no significant difference in taste meter value and setback, but there was significant difference in percentage of head milled rice, breakdown and peak viscosity; and Dongyou9901 had the best RVA property when grain filling for 35～40 d and Changlixiang had the best RVA during 35～45 d.
