| 摘 要： | 温度在25℃之内,番茄光合速率随温度的升高增加较快,35℃以内光合速率随温度的上升而下降较慢,超过35℃光合速率迅速下降。高温引起光合速率下降有气孔因素也有非气孔因素。高温下叶绿素含量合成受阻,叶黄素、类胡萝卜素含量下降,且各种色素之间的比例也会发生一定的变化,并直接影响光能的吸收。

| Abstract: | When the temperature is below 25 ℃, the photosynthetic rate increases with the rise in temperature at a fast rate. When the temperature is below 35 ℃, photosynthetic rate decreases with the rise in temperature at a slower pace, but when the temperature is above 35 ℃ photosynthetic rate declines rapidly. The decline in photosynthetic rate caused by high temperature has something to do with stomatal factors and it also has something to do with non-stomatal factors. The synthesis of chlorophyll content are blocked because of high temperature. Content of lutein and carotenoids are decreased, and the ratio between various pigments is also changed which has a direct effect on the absorption of light energy. |
