| 摘要: |
| 在人工气候室内采用盆栽方法，研究了高温高湿胁迫对红花荷等26种园林植物叶片相对含水量、细胞质膜相对透性、可溶性蛋白含量和超氧化物歧化酶（SOD）活性等生理生化指标的影响，采用隶属函数分析法进行耐热性综合评价。结果表明，复羽叶栾树隶属函数值最高，对高温高湿的耐性最强，红花荷、黄槐、杜鹃红山茶、无忧树、火焰木、红花银桦、蓝花风铃木、红花羊蹄甲、黄花风铃木、仪花和芒果耐性较强，澳洲火焰木、宫粉羊蹄甲、红千层、腊肠树、美丽异木棉、深山含笑、樟树、糖胶树和海南红豆耐湿热性中等，而广宁红山茶、红花风铃木、猫尾木、乳源木莲和尖叶杜英耐湿热性弱。研究植物对高温高湿逆境的响应机制将有助于采取有效的措施来抵御高温高湿对植物的危害，为城市森林景观建设提供科学依据。 |

| Abstract: |
| Using phytotron to simulate high temperature and humidity environment, the study was made on physiological biochemical indexes of leaf relative water content, relative permeability of the cell membrane, soluble protein content, superoxide dismutase of Rhodoleia championii and others, and its comprehensive evaluation of heat resistance by analysis of subordinate function. The results showed that tolerance of the high temperature and humidity of Koelreuteria bipinnata was highest, followed by Rhodoleia championii, Cassia surattensis, Camellia azalea, Saraca dives, Spathodea campanulata, Grevillea banksii, Bauhinia blakeana, Tabebuia chrysantha, Lysidice rhodostegia, and Mangifera indica, which tolerance of the high temperature and humidity of Brachychiton acerifolius, Bauhinia variegate, Callistemon rigidus, Cassia fistula, Chorisia speciosa, Michelia maudiae, Cinnamomum camphora, Alstonia scholaris, and Ormosia pinnata was medium, while tolerance of the high temperature and humidity of Camellia chekiangoleosa, Bauhinia blakeana, Dolichandrone caudafelina, Manglietia yuyuanensis, and Elaeocarpus apiculatus was weak. The study of plants to high temperature and humidity stress response mechanism would be help to take effective measures against the hazards of high temperature and humidity on the plant has a guiding significance in the construction of urban forest landscape. |
