Germination of Lespedeza floribunda *** was studied in order to provide cultivation and application in gardening and *** indicated that the seeds of Lespedeza floribunda had the characteristic of forcing dormancy that was caused by hard seed *** dormancy could be released by soaking in hot water and by sulphuric acid *** most appropriate treatment time was 10～30 min,resulting in average germination rate(96%),average germination power(82.53%)and average germination index(17.54).The optimum germination temperature was 25 ℃ and the germination rate,germination power and germination index was 95%,81%,22.95 respectively after treated by sulphuric acid for 20 min.

The techniques of cutting propagation of Potentilla fruticosa was *** tender stem cuttings and the woody stem cuttings were treated by different concentrations of BBA(0 mg·kg-1,10 mg·kg-1,50 mg·kg-1,100 mg·kg-1,200 mg·kg-1,500 mg·kg-1).The results indicated that the rooting percentage of tender stem cuttings at the concentration of 10 mg ·kg-1BBA was the highest(88.3%),and that of woody stem cuttings treated by the concentration of 50 mg·kg-1BBA was the highest(66.67%).It also indicated that the rooting percentages of the tender stem cuttings were better than those of the woody stem cuttings with same treatment.
