Abstract: The stem sections were taken from new shoots of Prunus cerasifera which grew in field on May 15th and July 9th in 2018 respectively and were sterilized with alcohol and sodium hypochlorite. The sterile stem buds were proliferated on medium containing different concentrations of IBA, rooted in soil supporting medium, and then the plantlet were transplanted. The results showed that there was no obvious difference in the sterilization effect of the samples at different time, and the contamination rate was less than 10% and the germination rate was 100%. There was no obvious different effects between washing and no-washing by sterilized water after soaked in alcohol on sterilization. The propagation coefficient of the plantlet of Prunus cerasifera was 4.2 in 1/2MS medium added with 0.4 mg/L IBA when cultured for 60 day. The rooting rate of the plantlet of Prunus cerasifera cultured in soil supporting medium was 68.8%, which was obviously higher than that of the plantlet cultured in agar medium. The survival rate of the plantlet of Prunus cerasifera transplanted in soil supporting medium was 75.0%, which was obviously higher than that of plantlet in agar medium(33.3%). These results can provide basis for improving rapid propagation technique of Prunus cerasifera.
