Abstract: We used the leaves and stems of aseptic seedlings of 5 rose cultivars that can successfully live outside through the winter in Heilongjiang Province as explants to investigate callus induction and plant regeneration. The leaves and stems of the 5 rose cultivars could induce callus; media containing 2,4-D could induce callus better; and a high concentration of cytokinin was not suitable for callus induction. TDZ played an important role in callus differentiation; culture under light conditions was effective for callus differentiation; and callus differentiation decreased with increasing number of subcultures. Plant regeneration could be successfully induced from the callus of 2004-8 and 2004-9 in experimentation, and the callus differentiation rate of the 2 varieties was 45% and 38%, respectively.
