温度对优质食味籼稻产量及品质的影响
The Impact of Temperature on Yield and Quality of High-quality Indica Rice
摘要
Abstract
[Objective]To study the impact of temperature on the yield and quality of high-quality indica rice.[Method]20 heat-resistant and 8 heat-sensitive indica rice varieties were used as experimental materials.Four sowing dates were set to analyze the changes in yield and rice quality indicators.[Result]The results showed that with delayed sowing,the plant height decreased;in the heat-resistant group,the temperature during the first 10 days after heading was significantly negatively correlated with both the number of grains per spike and the grain filling rate.There was a noticeable trend of increasing grain length and length-to-width ratio,while alkali spreading value and gel consistency also decrea-sed.With delayed sowing,the amylose content showed an increasing trend in the heat-resistant group,while it fluctuated in the heat-sensitive group,with little difference.Grain length,milled rice rate,and alkali spreading value were all significantly negatively correlated with the temper-ature after heading.In the heat-resistant group,amylose content was significantly negatively correlated with the temperature after heading,where-as in the heat-sensitive group,there was no significant correlation.[Conclusion]For cultivating high-quality indica rice in the Jianghuai region of Anhui,it is recommended to arrange for heading in late August or early September.Varieties with an alkali spreading value of grade 6 or a-bove and amylose content between 16%and 18%respond relatively slowly to temperature changes,which is beneficial for improving eating quality.关键词
