| 摘 要： | 将两个春麦品种在春播和夏播条件下进行生理指标的测定,对测定结果进行比较,夏播的叶绿索a含量明显低于春播的叶绿素a含量,叶绿素a/b比值也因夏播的气候条件影响而下降。春播与夏播小麦的旗叶净光合速率无明显差异。春播与夏播的干物质累积曲线的形状十分相似,但随播期的推迟生长曲线向坐标的左方移动。

| Abstract: | Two spring wheat varieties were selected and sown in spring and summer respectively.Their physiological characteristics were determined and compared. The results are as follows: the content of chlorophyll a of the wheat sown in summer is significantly lower than that of wheat sown in spring.The ratio of chlorophyll a to b of the wheat sown in summer is also reduced probably because of the effect of the summer weather.There is remarkable difference between the net photosynthetic rates of the flag leaves of both types of wheat.And their curves of dry matter production are very similar.However, their growth curves move to the left side of the coordinates as their seeding time is postponed. |
