摘　　要：S330 7、B9都能抑制水仙的营养生长 ,使株高矮化 ,叶片挺拔 ,防止倒伏 ;使初花期延迟 ,花期延长 ,花朵直径增大 ,明显提高水仙的观赏价值。 5 0～ 40 0mg/L的S330 7能使营养生长期植株矮化 32 %～ 48% ,叶片干重增加 1 %～ 5 % ,叶片增厚 0～ 3% ,叶绿素含量提高 6%～ 2 8% ;初花期延迟 1～ 7d ,花期延长 3～ 9d ,花朵直径增大 0 0 3～ 0 45cm。 5 0 0～ 40 0 0mg/L的B9能使植株矮化 3%～ 2 3% ,叶绿素含量提高 6%以内 ,初花期延迟 3～1 4d ,花期延长 2～ 5d ,对叶片干重、叶片厚度及花朵直径影响不大。 2种药剂均能使主茎花序花朵数量增加 0 8朵。以 2 0 0mg/L的S330 7对水仙矮化和开花的效果最好。Both S3307 and B9 can inhibit the vegetative growth of Narcissus tazetta var.Chineasis, dwarf the plants, straighten the leaves, prevent lodging, postpone the first bloom and enlarge the flower diameter,to increase the ornamental value of the plants. An application of 50～400 mg/L of S3307 has an effect of dwarfing 32%～48% in the vegetative growth stage, with an increase of 1%～5% in leaf dry weight,0～3% in leaf thickness,6%～28% in chlorophyll content and 0.03～0.45 cm in flower diameter,at the same time,has postponed the first blooming for 1～7 days, prolonged the first blooming for 3～9 days. By contrast , an application of 500～4 000 mg/L of B9 has the effect of dwarfing the plants by 3%～23%,increasing the chlorophyll content by 6%,postponing the first blooming 3～14 days,prolonging the blooming period 2～5 days, while without much influence on leaf dry weight ,leaf thickness and flower diameter. Both of the two retardants have increased the flower number on the main stem of anthotaxy for 0.8.The experiments indicated that the best result would beobtained with the application of 200 mg/L of S3307.
