【摘要】 以“玫瑰”欧洲荚蒾、短序荚蒾、日本珊瑚树、台东荚蒾、粉团这5种荚蒾幼苗为试验材料，进行全光照、遮阴53.66%、遮阴80.15%的处理，测定不同遮阴处理下株高、冠幅、叶面积、叶片相对含水量、比叶面积、可溶性糖含量及SOD活性等形态和生理指标。结果表明：5种荚蒾均会通过外观形态改变及生理响应的方法来适应弱光环境。通过相关性分析、主成分分析对5种荚蒾的耐阴性进行综合评价，结果显示，5种荚蒾耐阴性表现为粉团>日本珊瑚树>短序荚蒾>台东荚蒾>“玫瑰”欧洲荚蒾。更多还原

【Abstract】 In this paper, the seedlings of Viburnum opulus ‘Roseum’, Viburnum brachybotryum, Viburnum awabuki, Viburnum taitoense, and Viburnum plicatum were used as materials, the morphological and physiological indexes such as plant height, crown width, leaf area, leaf relative water content, specific leaf area, soluble sugar content and SOD activity were measured under different shading treatments of full light, shading 53.66 % and shading 80.15 %.The results showed that the five Viburnum species could adapt to the low light environment through morphological changes and physiological responses.The negative tolerance of five Viburnum species was comprehensively evaluated through correlation analysis and principal component analysis, and they ranked as follows :Viburnum plicatum>Viburnum awabuki>Viburnum brachybotryum >Viburnum taitoense >Viburnum opulus ‘Roseum’.更多还原
