| 摘 要： | 用LI-6400光合系统分析仪,测定了7种园林树种的生理生态指标的日变化。结果为:水分利用效率就日平均值而言,依次为欧洲丁香(8.74)>棣棠(8.20)>紫藤(6.76)>玉兰(6.39)>小花溲疏(4.62)>连翘(3.46)>山桃(2.51)。结果表明,前3种园林树种相对于其他树木的水分利用效率较高。这些数据有助于在园林生产实践中进行树种的选择和作为制定水分管理措施的依据。 |

| Abstract: | Seven garden tree species were measured in July,2003,by using LI-6400 potable photosynthesis system.The results are as follows: The daily average WUE are 8.74,8.20,,6.76,6.39,4.62,3.46 and 2.51 for Syringa vulgaris,Kerria japonica,Wisteria sinensis,Magnolia denudata,Deutzia parviflore,Forsythia suspense and Prunus davidiana,suggesting that the first 3 tree species have relatively higher water use efficiency than others.Information and data presented here are helpful to choose treee species and guide the water management during the garden practices. |
| Keywords: | garden trees net photosynthesis rate transpiration rate water use efficiency |
