多效唑在植物生产上的应用现状

Application of Paclobutrazol in Plant Production

多效唑是一种植物生长延缓剂,具有延缓植物生长、抑制茎枝伸长,促进分蘖,促进成花和座果,增强抗旱及抗寒性,提高耐盐性和延缓植物衰老等多种效应。本文从组织培养、抗逆性研究、产质量研究以及残留问题等方面综述了多效唑在植物生产中的应用和研究情况,为多效唑在植物生产上的应用研究提供方便。

As a kind of plant growth retardant, paclobutrazol could inhibit plant growth and stem elongation, facilitate formation of tillers, flowers and fruits, enhance resistance to drought, cold and salt, and slow down plant senescence. Research and application of paclobutrazol （PP333） in production from the aspects of tissue culture, resistance, yield and quality as well as paclobutrazol residues are reviewed to facilitate applied research of paclobutrazol （PP333） in plant production.
