| 摘 要： | 通过测试9种木兰科植物的光合特性,结果表明:自然状态下,9个树种的净光合速率曲线多呈双峰型,与光照强度呈一定程度的负相关性,但杂种鹅掌楸的净光合速率曲线与其他差异大.从光合作用与其影响因子之间的线性关系可以获得相关系数并建立回归方程为y=0.599-0.001Rc-0.003PAR 0.036Rm-0.274Ta 0.005Gs 0.408Tl-0.014ci.并测算出单位叶面积的光合作用引起的固碳放氧能力.

| Abstract: | By the test of photosynthetic characteristics of 9 Mognoliaceae Species,the results showed: Under natural state,most of photosynthetic-rate curves among 9 species were double peak types,having some extents of negative correlation with PAR.But the curves of Liriodendron hybrida was different from others.The regression equation between photosynthetic and its influence factors was:y=0.599-0.001Rc-0.003PAR 0.036Rm-0.274Ta 0.005Gs 0.408Tl-0.014ci.And it was given the capacity of carbon fixation and oxygen release by photosynthesis in a unit leaf area. |
