Abstract:

The paper described the mechanism and classification of dwarfing agents, analyzed their effect on the height, stress resistance, flowering index and endogenous hormone of ornamental plants, summarized their application methods, effect and persistence, and pointed out the existing problems. At present, the research on the dwarfing agents’ application in ornamental plants is not comprehensive, and the application time, the residue pollution and the dwarfing mechanism still need further study. In order to use the dwarfing agents more efficiently in the production process, studies on the various aspects of dwarfing agents should be further enhanced, so that the dwarfing agents can be widely applied to large-scale and industrial production of ornamental plants with dwarfing requirements, to improve the economic benefit, regulate and control the plant shape in accordance with the market demand, and promote the development of the ornamental plant industry.

Key words: dwarfing agent, dwarf, gibberellin, florescence, plant endogenous hormones
