| 摘 要： | 通过对新疆北部地区城市园林绿化中应用最多的26种园林树的光合作用、水分生理等生理指标的测定及对测定结果的比较分析表明：白榆和紫穗槐的净光合速率明显高出其它24种树木；榆叶梅和夏橡在光能利用效率方面与其它树种相比显得非常显著；紫穗槐的蒸腾速率远高于其它树种；白柳的水分利用效率最高。大部分园林树种的净光合速率与光能利用效率之间存在正相关；蒸腾效率与水分利用效率之间存在明显的互补性。

| Abstract: | The comparison and analysis on physiological characteristics of light and water of 26 ornamental trees were conducted based on their application in the north of Xinjiang.The results indicated that the net phosynthetic rate of ulmus pumila and Amorpha fruticosa has relatively higher than that of other 24 ornamental trees. Loniseania triloba and Quercus robur are more remarkable than the other ornamental trees in light use efficiency(LUE);the transpiration rate( E) of Amorpha fruticosa is higher than that of the other ornamental trees; Salix alba has the highest water use efficiency(WUE).There is a positive correlation between Pn and LUE of the most ornamental trees and a distinguish negative correlation between E and WUE. |
