Abstract:
Thirteen kinds of flowers Persicaria amplexicaulis ‘Firetail’,Miscanthus sinensis var.purpurea,Physostegia virginiana ‘Crown of Snow’ and so on a randomized block design with three replicates in the experiment were adopted,the strength of salt tolerance(0.2%,0.4%,0.6%,0.8%,1.0%,1.2%,1.4%,1.6%) of different perennial flowers were studied and compared,and the relative germination percentage,root length,simply vigour index were measured,to determ salt tolerance of the plants,using membership function method.The results showed that the order of salt tolerance of thirteen flowers was Persicaria amplexicaulis ‘Firetail’> Miscanthus sinensis var. purpurea> Coreopsis basalis> Hibiscus grandiflorus> Physostegia virginiana ‘Crown of Snow’> Aster dumosus ‘Purple Dome’> Achillea millefolium ‘Paprika’> Achillea millefolium ‘Summerwine’> Astilbe chinensis ‘Visions in Pink’> Althaea rosea> Rudbeckia fulgida ‘Goldsturm’> Astilbe ×arendsii ‘Gloria Purpurea’> Viola philippica Car.
