Abstract: Based on the domestication and new variety breeding of resistance to adversity of the low ground cover plants in blossom, a test of shade tolerance, drought tolerance and pruning tolerance of germplasm of wild Potentilla reptans var. sericophylla of was carried out. Nursery trials conducted in Shanxi Agricultural University. The results showed that under different shade stress, Potentilla reptans var. sericophylla chlorophyll a/b ratio was generally low. The coverage, tiller ability, the number of stolons and height, etc. were affected to different degrees. No significant difference among the treatments. Under drought stress, proline accumulation of Potentilla reptans var. sericophylla was significantly increased, conductivity changes smoothly, stolons had shorter refractory period to moderate drought stress and strong growth resilience; Potentilla reptans var. sericophylla after heavy pruning process could recover the ground in about 20 days, the plants treated with moderate pruning could recover the ground in about 10 days. It is indicated that curly creeping Potentilla has a strong tolerance to pruning.
