摘　　要：以5种优质稻谷为试验材料,分别于25℃、50%相对湿度和37℃、70%相对湿度条件下贮藏,研究优质稻谷主要贮藏品质(发芽率、丙二醛含量以及脂肪酸组成成分)的变化。结果表明,短期陈化过程中,高温高湿会抑制优质稻谷的种子活性,使其发芽率显著降低,同时增加稻谷的丙二醛含量,但稻谷脂肪酸组分相对含量在短期贮藏内较为稳定。与籼粳杂交稻(甬优17、甬优7850、甬优1540)相比,粳稻(秀水14、浙粳99)多项指标变化明显,说明其贮藏品质较易发生劣变。In order to study the quality deterioration of high-quality rice,five kinds of high-quality rice were stored under the conditions of 25℃,50%RH and 37℃,70%RH.The processing quality varies such as germination rate,malondialdehyde,and fatty acid composition.The results showed that during short-term storage,high temperature and humidity inhibited the seed activity of high-quality rice,significantly reduced its germination rate,and increased the MDA content of rice.However,the relative content of fatty acid components in rice grains was relatively stable and less affected by high-temperature and high-humidity conditions during short-term storage.At the same time,compared with indica-japonica hybrid rice,many indicators of japonica rice modified significantly,indicating that its storage quality is more prone to deterioration.
