一般情况下,水稻生长季的初期,低温天气较多,水稻幼苗的叶色会随着温度而变化。低温是引起幼苗叶变黄、生长受阻的主要原因。本研究主要研究低温对叶绿素形成的影响及叶绿素的形成与叶色减退的关系。试验选用三个品种:G.S.10231(日本品种)、CNM20(IR-8中选出的和 IR-8。在不同的时期播种,这样,各区就在不同的温度下生长:9.3°～25.2℃和14.9°—28.8℃,并于播
Under normal circumstances, the early rice growing season, cold weather is more, the leaf color of rice seedlings will change with temperature. Low temperature is the main reason causing the yellowing of seedling leaves and the obstruction of growth. This study mainly studied the effect of hypothermia on the formation of chlorophyll and the relationship between the formation of chlorophyll and the decrease of leaf color. Three varieties were selected for the experiment: GS10231 (Japanese variety), CNM20 (IR-8 and IR-8) sown at different times so that the zones grew at different temperatures: 9.3 ° to 25.2 ° C and 14.9 ° -28.8 ℃, and broadcast
