[目的]研究灌浆期高温胁迫对早籼稻碾磨、外观和蒸煮食味品质的影响,揭示早籼稻品质性状对灌浆期高温胁迫的响应规律.[方法]以R996、湘早籼45号和6个新育成的早籼稻品系为试验材料,以分期播种方式利用自然高温进行胁迫处理,分析了供试品系的碾磨、外观和蒸煮食味品质,筛选出对高温钝感和敏感的水稻品系,探究稻米品质性状对灌浆期高温胁迫的响应规律.[结果]稻米品质性状对灌浆期不同时段温度的敏感性不同,始穗后10 d内温度对稻米碾磨品质和蒸煮食味品质影响最显著,始穗后30 d内温度对稻米外观品质影响最显著.稻米品质对灌浆期高温胁迫的响应因性状而异,灌浆期高温胁迫显著降低糙米率、精米率、整...

[Objective]This study aims to investigate the impact of high-temperature stress during the filling stage on the milling,appearance,cooking,and eating quality of early indica rice and to reveal the response patterns of quality traits in early indica rice to high temperatures during the filling stage.[Method]Experimental materials included R996,Xiangzaoxian 45,and six newly bred early indica rice varieties.Natural high-temperature stress treatment was applied through staged sowing.The milling,appearance,and cooking and eating qualities of the eight varieties were analyzed.Heat-insensitive and he...
