Drought Resistance Comparative Research of Four Shade Ground Cover Plants

Based on the observation of the growth potential,free proline content,critical water saturation deficiency,leaf water retention and root / shoot ratio of the following four shade ground cover plants: Sedum baileyi,Selaginella uncinata,Pellionia radicans and Lysimachia hemsleyana,after using drought stress treatment,the drought resistance difference of those four species was found.The better drought resistance plants were Sedum baileyi and Selaginella uncinata,Pellionia radicans and Lysimachia hemsleyana were the worse species.
