| 摘 要： | 以金叶榆、金枝梾木和俄罗斯红叶李3种彩色树2a生苗木为试材,测定了不同程度干旱胁迫下净光合速率、蒸腾速率、细胞膜透性、叶片含水量以及高生长等指标,分析了3种彩色树的抗旱性。结果表明:在轻度干旱胁迫条件下,金叶榆和金枝梾木受到的影响小于俄罗斯红叶李;重度干旱条件下,金叶榆表现出较强的抗旱性,而金枝梾木和俄罗斯红叶李受到的影响较大。3种彩色树的抗旱性强弱排序为:金叶榆金枝梾木俄罗斯红叶李。

| Abstract: | A comparative study of the drought-resistance of three colorful trees such as Ulmus pumila cv.jinye,Cornus stolonifera var.glariamea and Prunus cerasifera,was carried out,according to the main physiological indexes of two-year-old seedings on different levels of drought stress,including the photosynthetic rate,transpiration rate,membrane permeability,relative water content,high-growth and so on,the drought resistance of three colorful trees was analyzed.The results showed as follows: at mild drought stress ... |
