中文摘要:
      选取三江平原主栽水稻品种龙粳29、龙粳31和龙粳46,应用人工气候箱在水稻抽穗期和灌浆期进行低温处理,[目的]通过对水稻外观品质、营养品质和RVA谱特征参数的分析,研究水稻发育中后期低温对品质影响。[结果]在抽穗期和灌浆后期经低温处理后对水稻外观品质的影响较大,各生育期蛋白质含量均显著上升,RVA谱特征一级参数均显著下降,直链淀粉和二级参数因品种差异有升有降。本次研究的性状中共有17对极显著相关和5对显著相关,最高粘度的相关性最大,与6个性状有相关性,垩白粒率与5个性状有相关性等,每个性状至少有两个或两个以上性状相关联。[结论]该试验根据低温对水稻品质影响进行判断,为三江平原水稻品质认证提供理论依据,同时也为水稻生产栽培和抗性育种提供理论依据。
英文摘要:
      Three major rice varieties of Sanjiang plain,‘Longjing 29’,‘Longjing 31’and‘Longjing 46’are chosen as materials and treated under low temperature at the heading and filling stages with artificial climate box in order to reveal the effect of low temperature on rice quality during mid and late growth period by analyzing rice appearance quality, nutritional quality and RVA profile parameter. The results indicated that: low temperature treatment at the heading and late filling stage greatly affected rice appearance quality; the protein content increased significantly at each growth stage while RVA primary parameter decreased; amylose content and RVA secondary parameter went upwards and downwards respectively on account of genotypic differences. Among all the characters studied, 17 pairs had extremely significant correlations and 5 pairs had significant correlations. The peak viscosity had the greatest correlation with 6 characters, and chalky rice rate had correlations with 5 characters. The results also showed that every character had correlation with two or above two characters. Based on the effect of low temperature on rice quality, this experiment provides references not only for rice quality certification in Sanjiang plain, but also for rice cultivation and resistance breeding.
