矮化剂作用机制及其在观赏植物上的研究进展

Dwarfing Agent:Mechanism of Action and Research Progress in Ornamental Plant

文章叙述了矮化剂的作用机制及分类,分析了矮化剂对观赏植物株高、抗逆性、开花指标及内源激素的影响,对矮化剂施用方法、作用效果与持续性进行总结,并指出目前存在的问题。现阶段矮化剂在观赏植物的研究不够全面,在矮化剂应用阶段、污染残留问题及矮化机理等方面有待深入研究。为了在生产过程中能够更加高效、合理地使用矮化剂,应继续加强矮化剂的各方面研究,使之广泛应用于有矮化需求的观赏植物规模化和工厂化生产中,提高经济效益,调控符合市场需求的植物株形,促进该类观赏植物产业化发展。

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.
