研究水稻结实期的温、光条件对稻米蛋白质与氨基酸含量的影响，其结果表明：同一品种作早季栽培时，稻米氨基酸含量比作晚季栽培时低；分期播种时，以结实期日平均气温为２４°Ｃ时蛋白质含量为最高；不同海拔高度种植时，以８００ｍ处蛋白质含量为最高；结实期人工高温（昼／夜＝３６／３０°Ｃ）处理，稻米蛋白质和氨基酸含量降低，低温（２１／２０°Ｃ）处理时，粳稻的氨基酸含量增加而籼稻则有所降低，籼稻氨基酸形成的适温在２４～２６°Ｃ之间。弱光下，糙米千粒重减轻，而其氨基酸含量增加。
The results showed that the content of amino acids in rice was lower than that in the late-season cultivation when the same variety was used as the early-season cultivation. When the sowing was carried out, the daily average temperature during the grain-filling period The highest protein content was at 24 ° C, the highest protein content was at 800 m at different altitudes, and the protein and amino acid contents were reduced at artificial daytime / night = 36/30 ° C, 21/20 ° C), the amino acid content of japonica rice increased while that of indica rice decreased, while that of indica rice was between 24 ~ 26 ° C. Under low light, the grain weight of brown rice lightened, while its amino acid content increased.
