To establish the induction and culture system for the somatic embryo of Paeonia suffruticosa,the zygotic embryo、hypocotyl and cotyledon were used as explants to test the effects of the period of seed embryo、different concentrations of sucrose and mediums to the induction of somatic embryo.The results showed that 110d after flower were the best period to collect explants for the induction,the induction was 33.0%,the best explant was zygotic embryo.Treating 2h with the 90.0g/L sucrose were best to the inducti...
