| 摘 要： | 为了揭示C3和C4作物气孔导度和叶片内部导度对光合作用制约性的差异,以大豆和玉米为研究对象,对气孔导度和内部导度进行了对比分析.结果表明,大豆的气孔导度大于玉米,而玉米的内部导度大于大豆,这说明玉米的光合作用主要受气孔限制,大豆的光合作用主要受羧化能力限制.玉米可以利用低浓度的CO2进行光合作用,但同时也因气孔导度低而... |

| Abstract: | To demonstrate the difference between stomatal conductivity and inter conductance of C3 and C4 crops,this paper compared the two conductivities by using soybean and corn.The results showed that the stomatal conductance in soybean was higher than corn,but inverse results were found for inter conductance.The difference indicated that leaf photosynthesis of corn was mainly constrained by stomatal conductance and leaf photosynthesis of soybean was mainly constrained by carboxylic ability.CO2 deficit could occur... |
