摘要 [目的]研究不同浓度B9和CCC对菊花生长及部分生理指标的影响,为菊花矮化栽培提供理论依据。[方法]采用盆栽试验,对菊花喷施不同浓度(500、800、1000、1200和1500 mg/L)的B9和CCC,研究B9和CCC对菊花生长、开花及部分生理指标的影响。以喷清水为对照。[结果]当B9浓度大于1000 mg/L或CCC浓度大于1200 mg/L时,菊花的株高、分枝数和叶片数显著减少,矮化效果明显;B9和CCC都可使菊花的开花期有不同程度的延迟;喷施B9和CCC后菊花叶片中叶绿素和可溶性糖含量显著增加,叶色加深,光合效率增强。[结论]1000 mg/LB9和1200 mg/LCCC在改善菊花株型,提高其观赏价值和生理品质等方面的综合效果较好。 [Objective] The study was to research the effects of B9 and CCC with different concn.on the growth,flowering and physiological characteristics of Chrysanthemum morifolium and provide the theoretical basis for dwarfing cultivation of C.morifolium.[Method] In the pot test,with the treatment of spraying clear water as CK,B9 and CCC with different concn.(500,800,1 000,1 200 and 1 500 mg/L)were sprayed on C.morifolium to study their effects on the growth,flowering and physiological characteristics of C.morifolium.[Result] The plant height,the branch number and the leaf number of C.morifolium were significantly decreased,and the dwarfing effect was obvious when B9 was higher than 1 000 mg/L or CCC was higher than 1 200 mg/L.B9 and CCC all could delay the flowering date to different degree.After B9 and CCC were sprayed on C.morifolium,the content of chlorophyll and soluble sugar in leaves was significantly increased,the leaf color became deeper,and the photosynthetic efficiency was increased.[Conclusion] 1 000 mg/L B9 and 1 200 mg/L CCC had better comprehensive effects on improving plant type of C.morifolium and increasing its ornamental value and physiological quality.
