| 摘 要： | 以4个强耐冷性粳稻品种和5个弱耐冷性粳稻品种为材料,比较分析了云南高原粳稻区不同海拔条件下不同耐冷性粳稻品种的稻米淀粉RVA谱变化特征。随种植海拔的升高,弱耐冷性品种的消减值明显增大,峰值黏度和崩解值显著减小,而强耐冷性品种的峰值黏度和崩解值呈先降后升趋势,消减值则表现先升后降趋势。强耐冷性品种的稻米淀粉RVA谱特性受海拔变化的影响较弱耐冷性品种小,蒸煮食味品质表现相对稳定,但弱耐冷性品种的蒸煮食味品质随海拔升高明显呈变劣趋势。 |

| Abstract: | Four cold-tolerant and five cold-sensitive japonica rice cultivars were grown at three locations with different altitudes in Yunnan plateau to investigate rice starch RVA profile characteristics.The results showed that with increasing altitude,the setback viscosity in cold-sensitive cultivars increased significantly,while the peak viscosity and breakdown viscosity decreased significantly.However,the peak viscosity and breakdown viscosity in cold-tolerant cultivars initially decreased and then gradually incr... |
| Keywords: | japonica rice cold tolerance rice quality starch viscosity altitude |
