Abstract： Magnoliaceae plants have a long history of cultivation and China is rich in wild resources of them. Magnoliaceae plants have high scientific value, ornamental value, ecological value and economic value. However, the existence of many Magnoliaceae plants is threatened due to the limited reproductive capacity and habitat destruction. The traditional propagation method is inefficient. Tissue culture technology promotes the conservation and utilization of Magnoliaceae plants. It can be applied in the conservation of endangered resources, breeding and commercial production of clonal seedlings. There are many studies on the in vitro shoot propagation, and the system has been relatively perfect. Some studies can achieve rooting seedlings through this way. There are few studies on organogenesis, and the problems of callus induction and adventitious bud differentiation have not been solved effectively. Also, there are few studies on the somatic embryogenesis. This paper reviewed the research on different regeneration ways of Magnoliaceae plants such as in vitro shoot propagation, organogenesis and somatic embryogenesis. The influences of explant selection, basic medium selection, growth regulator concentration and culture condition on in vitro growth of Magnoliaceae plants were discussed. Meanwhile, the paper summarized the problems and the solutions of rooting and browning, and prospected the future research directions. It will provide theoretical basis and technical reference for rapid propagation of Magnoliaceae plants.
