| 摘 要： | 通过盆栽苗木水分胁迫试验，对鄂西北地区主要造林树种的耐旱生理特性进行了对比研究，着重分析了在水分胁迫条件下湿地松、杉木、刺槐、侧柏、沙棘(引种)、柠条(引种)等树种的形态、水分生理、生理代谢等指标的变化特征，并以此为依据，对以上苗木耐旱特性进行了综合评价。结果表明，6个供试苗木都具有较强抗旱性能，而其中柠条、侧柏抗旱能力比湿地松、杉木、刺槐、沙棘的要强。

| Abstract: | Based on the experiment of water stress in pots,the drought tolerance characteristics of the main afforestation trees in northwest Hubei province were studied.The index variation characters of shape,water relations and physiological metabolism of Pinus elliottii,Couninghamia lanceolata,Robinia pseuidoacacia,Platycladus orientalis,Hippophae rhamnoides(introduction),and Caragana korshinskii(introduction) under water stress were (emphatically) analyzed;based on that,the drought tolerance characteristics of potted trees were synthetically evaluated.The results showed that six seedling trees for testing had stronger ability of fighting the drought.The ability of fighting the drought of Caragana korshinskii and Platycladus orientalis were stronger than that of Pinus elliottii,Couninghamia lanceolata and Robinia pseuidoacacia. |
