| 摘 要： | 对5个夏玉米杂交种叶片光合特性的研究表明,不同叶位叶片的叶绿素含量、可溶性蛋白含量的动态表现形式基本相同,在叶片展开后达到最大值,随后缓慢下降,后期降低迅速,而光合速率在叶片全展时达到最大值.玉米生育后期,15片叶中可溶性蛋白含量较高,18片叶的光合速率大于其它叶片.

| Abstract: | The leaf photosynthetic characteristics of 5 corn hybrids were studied.The results showed that the pattern of the course of dynamic changes of the chlorophyll content and the soluble protein content of leaves at different positions were approximately the same,their maximum values appeared after the leaves full expansion,then gradually decreased when the leaves were getting old,but the photosynthetic rates of leaves at different positions reached the maximum values at leaves full expansion.During the last phase of growth and development of the corn plant,the soluble protein content of the 15th leaf and the photosynthetic rates of the 18th leaf were higher than others. |

| Keywords: | corn leaves chlorophyll content soluble protein content photosynthetic rate |
