| 摘 要： | 用LI-6400红外气体分析仪对厦门市不同生境条件下城市绿化树种的光合特性进行测定,结果表明:在全光照条件下的树种在不同时间段净光合速率均强于受城市环境影响树种,午休现象不明显,而受光照、水分和温度等城市环境胁迫影响,城市中绿化树种逐渐适应在弱光条件下进行光合作用.树种间的光合特性与能力存在明显差异,在光能利用率水平上...

| Abstract: | Photosynthetic characteristics of urban greening tree species in Xiamen city were studied under different habitats by using the Li-6400 infrared gas analyzer.Result shows that the net photosynthetic rate of plants under full light without noon depression is more than that of plants under the impact of urban environment.The urban greening tree species gradually adapt to photosynthesis in poor light under influence of environmental factors such as sunlight,water & temperature.Photosynthetic & capacity among s... |
