In order to establish the regeneration system of Cerasus serrulata var. lannesiana cv. ‘Grandiflora’, the effects of different explants and plant hormone combinations on callus induction, adventitious bud differentiation, proliferation and rooting were studied using perennial mother plant leaflets, annual grafted seedling leaflets, axillary bud induction leaflets and proliferative first-generation leaflets as explants. The results showed that callus could be induced from all four explants, and adventitious buds could be derived from all explants except the leaflets of perennial mother plants. The higher the degree of explants’ juvenility, the greater the success of subsequent culture, with the best explants were the proliferative first generation leaflets. The best medium for callus induction was MS+0.5 mg·L^-1 6-BA+1.0 mg·L^-1 2,4-D, and the induction rate was 96.22%. The optimal medium for differentiation was MS+1.0 mg·L^-1 6-BA+0.1 mg·L^-1 2,4-D+0.1 mg·L^-1 TDZ, and the differentiation rate was 78.14%. The optimal medium for proliferation was MS+1.0 mg·L^-1 6-BA, and the proliferation coefficient reached 7.85. The optimal medium for rooting was 1/2MS without any hormone, and the regenerated plants with 100% rooting rate were obtained. The regenerated plants from different explants grew very differently, and those induced from first generation of proliferative leaflets had the best growth.
