| 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,... |
