| 摘 要： | 以霸王(Zygophyllum xanthoxylum)种子为材料,通过盆栽试验进行水分胁迫处理并分析其幼苗期叶片生长生理特性的变化及其与长期水分利用效率之间的相关关系.结果显示,1)霸王幼苗总叶面积、单叶面积随着水分胁迫的加剧显著减小,严重胁迫使总叶数急剧减少,与中度胁迫处理相比减少了51.2%;2)水分胁迫显著降低...

| Abstract: | The pot experiment was carried out to deal with leaf physiological characteristics and water use efficiency of Zygophyllum xanthoxylum seedlings under different water stress.Meanwhile,the correlation between leaf physiological characteristics and water use efficiency were also analyzed.The results of this study showed that,1) the total leaf area and single leaf area activity decreased with the decrease of soil water content.Total number of leafs on severe drought was sharply reduced by 51.2% compared with t... |
