摘　　要：以对光周期敏感的14个观赏大菊[Dendranthema morifolium(Ramat.)Tzvelev]为试材,研究了不同浓度丁酰肼和不同喷施时间对大菊观赏性状的影响。结果表明,不同浓度的丁酰肼对同一品种株高影响较大,同一浓度丁酰肼对生根快、中、慢三类型的大菊品种株高影响较小。每7 d处理的2个浓度丁酰肼,处理浓度越高,抑制植株的株高生长越明显。在同一浓度的处理下,每10 d处理更适合调节菊花植株株高。对于大多数品种,每10 d喷施一次3 g/L丁酰肼对株高控制为最佳。不同浓度丁酰肼对观赏大菊品种的花径、叶长、叶宽、节间长、茎粗等有明显影响,对株高具有抑制作用,综合数据表明,每10 d喷施一次3 g/L的浓度处理对大菊株高处理效果最佳。Fourteen ornamental chrysanthemums[Dendranthema morifolium(Ramat.)Tzvelev]sensitive to photoperiod were used to study the effects of different concentrations of daminozide and spraying time on their ornamental characters.The results show that different concentrations of daminozide had a greater effect on the plant height of the same variety,and the same concentration of daminozide had a smaller effect on the plant height of three types of chrysanthemum varieties with fast rooting,medium rooting and slow rooting.With the increase of concentration treated for every 7 days,the inhibition of plant height growth of chrysanthemum was more obvious.The plant height of chrysanthemum was better sprayed at the same concentration for every 10 days.For most varieties,3 g/L daminozide was the best concentration to control the plant height once every 10 days.Different concentrations of daminozide had obvious effects on flower diameter,leaf length,leaf width,internode length and stem diameter of chrysanthemum varieties.Daminozide could inhibit plant height.The treatment of 3 g/L daminozide every 10 days had the best effect on the height of chrysanthemum.
