The plants of the Lycoris genus are precious flower bulb resources of China. However, they are restricted by the long life cycle and low proliferation, and cannot meet the needs of commercial production. For effective asexual propagation methods, scales cutting, spray cultivation and tissue culture were conducted in L. radiate. For the scales cutting in substrate, the highest budding rate and propagation coefficient reached 80.5% and 7.2, respectively. Spray cultivation of bulb pieces was proved to be an effective method for bulblet reproduction of Lycoris, which generated more buds and higher propagation coefficient as 9.8. 5 g/L activated carbon effectively prevented the browning of explants during tissue culture. Medium component with 10 mg/L BA and 0.5 mg/L NAA was proved best for buds inducing and proliferating. Furthermore, we carried out the enrichment analysis of pathways during bulb development, and got some genes related to starch and sucrose metabolism, which will beneficially support the further molecular breeding of Lycoris.
