| 摘 要： | 对兰州市特殊空间生态环境下引种栽培的14种园林绿化植物的适应性(耐荫性、抗寒性、抗污染性)进行了试验研究.结果表明:植物叶片内叶绿素含量、叶绿素a/b值以及植物在逆境胁迫下丙二醛的含量不仅取决于该植物种的生理特性和生化反应能力,也取决于栽培物种对生态环境的适应性(抗逆性)应变能力.供试植物中小叶扶芳藤的耐荫性最强,鹅绒藤的最弱;三叶地锦的抗寒性和抗污染性最弱;而景天科植物的抗寒性与抗污染性均最强.

| Abstract: | Based on two physiological indexes, the adaptability of 14 species of landscape plants introduced to the special space in Lanzhou City,such as shade-tolerance,cold resistance and pollution-resistant, were studied. The results showed that the content of chlorophyll, the Chla/Chlb value and the content of MDA under the stress were decided by the physiological characteristics and the adaptability for the special space. The shade-tolerance of Euonymus forthunei var. radicans was better than others,and the shade-tolerance of Cynanchum Chinese was less than others ; the cold-resistance and pollution-resistance of Parthenocissus tricuspidata was less than others ; but three species of the family Crassulaceae were better than others. |
