玉米叶片的光强——光合速率曲线的形状和走向直接反应了玉米对光能利用的情况.因此,研究描述光强——光合速率的数学模型,从理论上分析玉米对光能利用的情况具有重要的意义.我们测定了三个玉米杂交种在三种密度下灌浆期果穗叶的光强——光合速率曲线.统计分析结果表明:净光合速率(P_N)同光强度(Ⅰ)之
The shape and direction of the light intensity-photosynthetic rate curve of maize leaves directly reflect the utilization of light energy by maize.Therefore, the mathematical model describing the light intensity-photosynthesis rate is studied, and the utilization of light energy by maize is theoretically analyzed Which is of great importance.We measured the light intensity-photosynthetic rate curves of three corn hybrids at grain filling stage under three densities.The statistical analysis showed that the net photosynthetic rate (P_N) and light intensity (Ⅰ)
