摘　　要：[目的]为引种和开发抗旱性芳香植物提供一定的理论依据。[方法]以多种芳香植物为研究对象,探讨植物受到干旱后植株叶片生理指标与形态指标的变化。[结果]在干旱胁迫下,几种芳香植物的生长受到抑制,植株叶片含水量下降,脯氨酸含量升高。复水后,它们都能恢复良好的生长状态。[结论]在不同种类之间,薄荷和丁香罗勒抗旱性最强,缬草抗旱性最弱。[Objective] The research aimed to provide the theoretical basis for the introduction and the development of aromatic plants with drought resistance. [Method] The changes of physiological index and morphological index of several aromatic plants were studied after drought.[Result]Under drought stress,the growth of several aromatic plants was inhibited,leaf water content was decreased,and proline content was increased. Several aromatic plants could recover after re-watering. [Conclusion] Mentha haplocalyx Briq and Ocimum gratissimum Linn had the highest drought resistance,while Valeriana officinalis Linn had the lowest drought resistance.
