Abstract:

Lycoris is a genus of plants with flowering bulbs that have high ornamental and medicinal value, with a great potential of industry development. However, the slow growth and low regeneration efficiency of their bulbs under natural condition severely restrict the development of Lycoris industry. This review analyzed the physiological mechanism and regulatory measures of bulb and bulblet development respectively, and focused on the changes of carbohydrate metabolism and endogenous hormone regulation during these two biological processes. It also summarized the regulatory measures of bulb development, including exogenous hormones application, fertilization, and agronomic measures. In addition, this review pointed out the weak basic research and the imperfect supporting industrial technology system during the development of Lycoris industry, and provided suggestions on accelerating the industry, including strengthening the basic research of bulb development, forming high-efficiency breeding and ecological cultivation technology system, and building integrated industrial chain for Lycoris bulbs.

Key words: Lycoris, bulb development, bulblet development, high-efficiency breeding, industrialization development
