摘　　要：为丰富山东省园林绿化花卉的多样性,以6个品种荚蒾属植物为研究对象,对其在干旱胁迫下生理生化变化及抗旱性进行研究,结果表明:随着土壤相对含水量的逐渐降低,各荚蒾属品种生理生化指标呈现出相似的规律,相对电导率、MDA含量、脯氨酸含量逐渐升高;SOD、POD活性先升高后降低;叶绿素含量先升高后降低;净光合速率先下降再升高后降低。并通过主成分及聚类分析,选择出中华木绣球和雪球荚蒾2个抗旱性较强的荚蒾属品种,可以作为山东地区重点推广的观赏品种。In order to enrich the diversity of landscape flowers in Shandong Province,this study took six introduced Viburnum L.as the research object to study their physiological and biochemical changes and drought resistance under drought stress.The results showed that with the gradual decrease of soil relative water content,the physiological and biochemical indexes of each Viburnum L.showed similar laws,such as relative conductivity,MDA content,proline content increased gradually;SOD activity and POD activity increased first and then decreased;chlorophyll content first increased and then decreased;the photosynthetic rate first decreased,then increased and then decreased.Through principal component and cluster analysis,two varieties of pods with strong drought resistance,such as Viburnum macrocephalum Fortune and Viburnum plicatum Thunb were selected,which can be used as key ornamental varieties in Shandong Province.
