摘　　要：为探明多效唑(PP333)、烯效唑(S3307)、矮壮素(CCC)、比久(B9)等植物生长调节剂对杂交兰株型控制的影响,本研究以杂交兰‘双艺金龙’为材料,在喷施不同种类和浓度植物生长调节剂后,对株高、株幅、叶片长度、叶片宽度、新芽高度、新芽宽度等指标进行比较分析。结果表明,从株型控制的整体效果来看,4种植物生长调节剂的喷施均有控制杂交兰株型的作用,作用效果优劣先后排序为烯效唑、多效唑、矮壮素和比久,特别是喷施200 mg·L^(-1)烯效唑和800 mg·L^(-1)多效唑的株型控制效果最为显著。本研究结果为杂交兰株型控制的进一步研究提供了科学依据。In order to explore the effects of paclobutrazol(PP333),uniconazole(S3307),chlormequat chloride(CCC),and daminozide(B9)on plant type control of hybrid Cymbidium,‘Shuangyi Jinlong’was used as material to analyze the plant height,plant width,leaf length,leaf width,new bud height and width after spraying different concentrations of paclobutrazol,uniconazole,chlormequat chloride,and daminozide.The results showed that four kinds of plant growth regulators were able to control plant type of hybrid Cymbidium from the overall effect of plant type control.The best effects were obtained by uniconazole,and the order of other plant growth regulators was paclobutrazol,chlormequat chloride and daminozide. In particular,spraying 200 mg·L^(-1) uniconazole and 800mg·L-1 paclobutrazol could obtain the most significant effect. The results of this study provided scientific basis forfurther research on plant type control of hybrid Cymbidium‘Shuangyi Jinlong’.
