| 摘 要： | 以刺槐、榆树、臭椿、绒毛白蜡、杨树为试材,利用不同浓度盐溶液模拟盐胁迫条件,研究了盐胁迫对刺槐混栽苗光合特性的影响。结果表明：低盐胁迫下刺槐混栽苗的Pn、Ci、Cond同步下降,且相关性较高;而随着胁迫的增强,三者又有所增高,在高盐胁迫下（200mmol/L）又开始下降,但盐胁迫对不同混栽苗光合作用的伤害作用不同。

| Abstract: | Effects on Photosynthetic characteristics of pure and mixed seedlings of black locust were compared under Salt Stress in this paper.Results showed that at the low salt stress,the Pn and Ci and Cond of pure and mixed seedlings of black locust were reduced,the reduce intensity were more and more serious as the stress condition became heavier,and at the high salt stress,they were all begin to decrease,but the damages in different mixed seedlings of black locust under salt stress were different. |
