摘要
解析了2013年和2014年气候因素对稻米品质性状的影响,进行了水稻灌浆期温度与稻米品质性状相关关系分析。结果表明:年度间气候因素对稻米直链淀粉含量、蛋白质含量和崩解值的影响均达到极显著差异水平,对最高黏度影响不显著。气候因素中最主要的影响因素是水稻灌浆期温度。水稻灌浆期温度与稻米崩解值呈极显著正相关,与稻米蛋白质含量呈显著正相关,与直链淀粉含量呈极显著负相关,与最高黏度呈弱正相关。水稻灌浆期温度越高,稻米崩解值、蛋白质含量越高,而直链淀粉含量越低,与最高黏度无关。
This article resolved the effects of climate factors on rice quality traits in 2013 and 2014, and the correlation analysis were studied between rice grain filling of temperature and grain quality traits. The results showed that the effects of climate factors on the amylose content, protein content and breakdown of inter-annual were highly significant differences, the effect on the highest viscosity was not significant. The most important factor among the climatic factors was the temperature of the rice grain filling stage. Rice grain filling stage had a very significant positive correlation with rice disintegration, it had a significant positive correlation with the protein content of rice, and it was negatively correlated with the content of amylose content, and it had a weak positive correlation with the highest viscosity. The higher the breakdown value, the higher protein content of rice and the lower amylose content appeared with the higher the temperature during grain filling stage, and it was no relationship with the maximum viscosity.
