Abstract: Abstract :The light-light curve and CO2 curve of 14 potted ground cover plants , Paeonia lactifolia , Dendranthema grandif lorum , Senecio bicolor , Anemone hupehensis ,Hosta plantaginea , Trifolium repens , Viola phi llipica , Carex capillaries var .pohuashanensis , Iris lactea var .chinensis , Hemerocallis citrina , Hemerocallis fulva , Iris tectorum , Liriope platyphylla , and Matteuccia struthiopteris were determined by dysprosium light illumination.Light compensation point (LCP), light saturation point (LSP), net photosynthetic rate (Pn), apparent quanta efficiency (), CO2 compensation point and RuBisco relative activity of these plants were analyzed comparatively .The correlations of shade tolerance with Pn , and CO2 utilization ability were discussed by multifactor analyzing .The results showed that different ground cover plant had different light utilization characteristics . Viola phillipica ,Hemerocallis citrina , Hemerocallis fulva , Liriope platyphyllus , Matteuccia struthiopteris , Carex capillaries var .pohuashanensis , and Hosta plantaginea had lower LCP , meanwhile they had lower LSP .They can use low light quantum , and have strong shaded-tolerance .Iris tectorum , Iris lactea var .chinensis , Senecio bicolor ,Dendrenthema grandiflorum , Anemone hupehensis , Trifolium repen had higher LCP and LSP , and were sun ground cover plants .A significantly positive correlation was found between LCP and Pn , LCP and RuBisco relative cutivity .A negative correlation was found between LCP and .The order of ability to shade-tolerance of ground cover plants is Carex capi llaries var .pohuashanensis Matteuccia struthiopters Hemerocallis fulva Liriope platyphyllus Hemerocallis citrina Viola phillipica Iris tectorum Hosta plantaginea .[ Ch , 3 tab .23 ref .]
