补充资料：植物生长调节物质
| 植物生长调节物质 plant growth regulator 人工合成的能调节植物的生长、分化、发育的化学物质。其中许多种类的结构及作用与天然植物激素相似。另一些如生长延缓物质，化学结构和生理作用与天然激素无明显关系。广义的生长调节物质也包括天然植物激素。 由于植物激素含量极微，分离提取手续繁复，要耗用大量植物材料和有机溶剂，成本过高，一般不用于制备。 生长调节物质的作用常与天然激素相似，如催熟、促进生根、疏花疏果（促进离层形成）等。但曾经在除草剂用量中占很大比重的2，4-D和2，4，5-T都是使用严重干扰正常生理活动以致杀死植物的浓度，这在自然状态下的天然激素作用中是不会出现的。 农业上对生长调节物质的应用与否，由经济效益的高低来决定。如生长素类似物对棉花个别花涂抹能抑制脱落，但花费劳力太多，经济效益不高。至于花卉、果树、药用植物等经济作物，生产上具有劳力密集和技术密集的特点，允许采用较细致的操作方式，用生长调节物质调节器官分化、发育以增加产量和提高品质的余地很大。特别是在组织培养中，常以不同的激素种类和浓度或其组合，调节培养中的组织分化和生长。 常用的植物生长调节物质有：2，4-D、吲哚丁酸、2，4，5-T、萘乙酸、苯氧乙酸、2甲-4氯、激动素、6-BA、乙烯利、MH、矮壮素、矮健素、B9、调节膦等。 |
