Abstract: Davidia involucrate is listed as the first degree national protective plant. As its low rate of natural production, a number of artificial reproduction techniques have been proposed at home and abroad to provide some reference for the artificial reproduction of Davidia involucrate in future. The authors summarized typical artificial reproduction techniques of Davidia involucrate, including the seed reproduction, cutting reproduction, burying reproduction, high pressure seeding reproduction, grafting reproduction and tissue culture and so on, and analyzed the key points and better ways of these techniques in different stages. The comparison indicated that these reproduction techniques had certain inadequacies. Tissue culture was superior to other methods in terms of the time, quantity, condition, means and management of the seedling. Finally, the focus and direction of the future research of Davidia involucrate was put forward.
