摘  要:
以30 g/L蔗糖+75 mg/L柠檬酸溶液为对照,探究了不同浓度的6-BA和硝酸银处理对菊花(Chrysanthemum morifolium Ramat.)切花寿命以及瓶插过程中菊花花径、吸水量等指标的影响.结果表明,含有6-BA和硝酸银的处理均能延长菊花切花的瓶插寿命,其中处理1(30 g/L蔗糖+75 mg/L柠檬酸+20 mg/L硝酸银+0.5 mg/L 6-BA)的保鲜效果最佳,能增大切花花径4.07 cm;延缓切花衰老速度,减缓水分胁迫,使菊花切花瓶插寿命长达31 d.

摘  要:
By measuring the flower-path, the vase life and the amount of water absorption of Chrysanthemum morifolium Ramat., the effects of the different concentrations of 6-BA and AgNO3 on the preservation of Chrysanthemum morifolium Ramat.were studied with 30 g/L sucrose+75 mg/L citric acid as a control, and the appropriate fresh liquid formula was figured out.The results showed that the treatment with 6-BA and AgNO3 could prolong the vase life of cut Chrysanthemum morifolium Ramat. Among them, treatment 1(30 g/L Sucrose+75 mg/L Citric acid+20 mg/L AgNO3+0.5 mg/L 6-BA) could significantly increased the flower-path by 4.07 cm and slow down the aging process. Besides, the harm of water stress was reduced, and the vase life of cut chrysanthemum was increased to 31 days.
