摘要: 以垦鉴稻5号和垦稻12为材料,采用负压式土壤湿度计监测土壤水势,通过防雨棚内的盆栽控水试验,研究了水稻返青至成熟期进行-8~-10 kPa的间歇控水对寒地水稻品质影响。控水处理降低两品种的整精米率及各粒位籽粒的直链淀粉含量和消减值,提高了两品种各粒位籽粒的总蛋白质含量、球蛋白含量、谷蛋白含量、醇溶蛋白含量、最高黏度值和崩解值。因此,控水处理后,两品种各粒位米饭食味综合评分略有降低。

Abstract: With Kenjiandao 5 and Kendao 12 as materials, the effects of intermittent watercontrolling treatments at -8 to  -10 kPa of soil water potential on rice  grain quality in cold region   from reviving  to maturity were studied in a pot experiment  in  a chamber rainproof by examining soil water potential with a negative pressure soil moisture  meter.The results of  showed that head rice rate, amylose content, setback value of grains at different positions  decreased,  whereas protein content, prolamin  content, glutelin content, globulin  content, peak viscosity value and  breakdown value of grains at different positions   increased.  Therefore, the rice  taste value decreased.
