Guangdong Agricultural Sciencesket potential. It is
important to solve the problem of propagation of Lycoris from the provenance, especially the proliferation of bulbs, which can
make up the shortcomings of low survival rate of Lycoris seeds in conventional sowing and reproduction and low coefficient
of sub-ball reproduction.【Method】Four asexual propagation techniques of Lycoris were studied, including in vitro culture
of sterile seedlings from Lycoris seeds, in vitro culture of scales, basal incision and reproduction of scales, and basal incision
and reproduction of scales after 1/3 of the bulbs being removed. The indexes of proliferation rate, rooting rate, seedling
formation rate and growth condition were explored.【Result】The results of in vitro culture of sterile seedlings showed that
the germination rate, the induction rate of multiple buds, proliferation rate and rooting rate of and L. aurea were
all higher than those of L. sprengeri and L. longituba. The results of scale culture in vitro showed that different media had
great difference in the induction of the three kinds of Lycoris bulblets. For , after 3 to 4 weeks of culture, there were
