稻米品质既受遗传基因的控制,也受环境因素的影响。环境对稻米品质的影响比较复杂,目前国内研究尚少。水稻结实期是温度影响稻米品质的主要阶段。本试验是在人工气候条件下研究温度对不同类型水稻品种稻米形成和品质的影响,以期为优质米的选 育和栽培提供理论依据。 一、材料与 Rice quality is controlled both by genetic and environmental factors. The impact of environment on the quality of rice is rather complicated. At present, there are still few studies in China. Rice graininess is the main stage in which temperature affects rice quality. This experiment is to study the effect of temperature on the formation and quality of different types of rice varieties in artificial climatic conditions, in order to provide a theoretical basis for the breeding and cultivation of high quality rice. First, the material and
