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 rela-tive 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 mor-phological changes and physiological responses.The negative tolerance of five Viburnum species was comprehensively evaluated through correla-tion analysis and principal component analysis,and they ranked as follows:Viburnum plicatum＞Viburnum awabuki＞Viburnum brachybotryum＞Viburnum taitoense＞Viburnum opulus'Roseum'.
