摘　　要：为了有效控制盆栽除虫菊株高,采用不同浓度水平的丁酰肼(B9)、矮壮素(CCC)、多效唑(PP333)和烯效唑(S3307)4种植物生长延缓剂对白花除虫菊(Tanacetum cinerariifolium)盆栽苗进行矮化处理。结果显示,4种不同浓度植物生长延缓剂能不同程度地降低除虫菊盆栽苗植株高度、抑制株幅生长;矮化效果以及对株幅生长的抑制作用由强到弱依次是S3307、PP333、CCC、B9;综合考虑,200 mg/L B9喷施效果最佳,不仅促使盆栽除虫菊种苗株高明显矮化,盆栽植株高度降低为对照植株的30%左右,同时对植株的叶片发育与株幅的抑制作用相对其他处理较小,株幅生长为对照植株的70%左右;处理后的植株矮壮紧凑,较为适合盆栽。In order to control plant height of pyrethrum(Tanacetum cinerariifolium),B9,CCC,PP333,S3307 with different concentra⁃tion levels were applied and compared by foliar sprays on the potted plant.Results showed that all the four plant growth retardants had dwarfing effects on plant height with different extent as well as on inhibiting plant crown width.The dwarfing effects and negative ef⁃fects on plant growth were S3307,PP333,CCC,B9 from strong to weak.The optimum dwarfing treatment for pyrethrum was the application of 200mg/L B9.It not only reduced the height of potted plants to about 30%of that of the control plants,but also inhibited the leaf de⁃velopment and plant width of potted plants,the width of the plant was about 70%of the control plant,and the treated plant was short,compact and suitable for pot culture.
