摘　　要：在菊花(Chrysanthemum morifolium Ramat.)姹紫嫣红的苗期、光周期诱导期、绿蕾形成期和绿蕾期,分别用2、10、20、50 mg/L乙烯利(ETP)的水溶液对菊花进行叶面喷施,研究在不同时期喷施ETP对菊花姹紫嫣红花期的影响。结果表明,不同时期喷施ETP对菊花花期的调控效应不同,总体上随ETP浓度的升高效应增强。在苗期、光周期诱导期、绿蕾形成期喷施ETP推迟了菊花花期,其中以在光周期诱导期处理效应最强,50 mg/L ETP处理菊花姹紫嫣红初花时间比对照推迟了19 d;在绿蕾期喷施ETP提前了菊花姹紫嫣红的花期,50 mg/L ETP处理初花时间比对照提前了6 d。In the seedling stage, photoperiodic induction period, the green bud development stage and green bud stage of chrysanthemum, 2, 10, 20 and 50 mg/L ethephon（ETP） were sprayed to study the effects on the florescence of chrysanthemum. Results showed that the effects of ETP sprayed in different stage on the florescence of chrysanthemum were different, and the effects were strengthened along with the content of ETP increase. Sprayed in the seedling stage, photoperiodic induction period and the green bud stage development stage, ETP postponed the florescence of chrysanthemum. The effects of ETP sprayed in photoperiodic induction period were the strongest, especially the treatment of 50 mg/L postponed the florescence 19 d. Sprayed in green bud stage, ETP led to the florescence earlier than the control, the florenscence under 50 mg/L ETP treatment was 6 d earlier than the control.
