摘　　要：应用典型相关的分析方法,在大田生产条件下,通过对水稻不同生育时期的光温因子与产量构成因素及产量性状和品质性状的分析结果,发现在温光因子中,移栽期-始穗期日照、始穗期-成熟期积温对水稻的产量性状和品质性状的影响较大;在产量性状中,每穴穗数和结实率是受环境影响较大的性状;在品质性状中,蛋白质含量、垩白粒率、长宽比是受环境影响较大的性状。同时,灌浆结实期高温导致水稻结实率明显下降、千粒重略有提高;蛋白质含量、垩白粒率、长宽比受环境影响最大。Field and grain house trial was conducted in the year of 2006 and 2007, and the effect of temperature and light conditions at different growth stage on yield traits and quality of rice was determined by typical correlation analysis. Results showed that the illumination from transplanting to initial heading and the accumulated temperature from initial heading to maturing had significant effect on yield and quality traits. The yield traits of panicles per hill and percentage of filled grain,and quality traits of protein content,chalk rate, grain length to width were affected greatly by environment factors. Higher temperature at grain filling resulted in lower percentage of filled grain and higher 1000-grain weight. Protein content,chalk rate and grain length to width affected mostly by environment factors.
