Abstract:: Taking perennial wild ground cover plants of Alysicarpus vaginalis (L.) DC.，Melastoma dodecandrum Lour，and Viola inconspicua Bl. as materials.The effect of different substrates on cutting propagation of Alysicarpus vaginalis and Melastoma dodecandrum were investigated，and the effect of different concentrations of GA₃ on seed germination of Viola inconspicua were studied.In order to provide effective guidance for development and application of three new good wild ground cover plants.The results showed that Alysicarpus vaginalis was suitable to be propagated by using the cuttings in the mixed substrate that the ratio of the sand and soil was 50% respectively；the rooting rate reached 99.0%.The rooting effect of Melastoma dodecandrum was the best in the substrate of pure sand.And the rooting effect using the cuttings with the rooting power was better than with the yellow mud.GA₃ could improve the seed germination of Viola inconspicua.Thegermination rate reached 89% with the concentration of GA₃ of 500 mg/L to treat the seed.
