Abstract: The effects of different preservatives on vase life and quality of cut Gerbera jamesonii flower were studied. The results showed that prescription T₇ (20g/L Suc+200 mg/L 8-HQC+150mg/L CA+75mg/L KH₂PO₄·3H₂O+1g/L CaCl₂) was the best of the 7 various preservatives. It could extend the vase life of cut G. jamesonii flower significantly. Preservative no.7 (T₇) decreased decomposition rate of anthocyanidin and retarded the increase of pH value and relative plasmalemma permeability in petals of cut G. jamesonii flower.

摘要： 探讨不同保鲜剂对非洲菊切花的瓶插寿命、观赏品质以及生理生化指标的影响。结果表明,在供试7组保鲜剂中,以处理7(T₇):20g/L Suc+200mg/L 8-HQC+150mg/L CA+75 mg/L KH₂PO₄·3H₂O+1g/L CaCl₂的保鲜效果最佳,可显著延长非洲菊切花瓶插寿命;T₇处理有利于减缓花瓣组织pH上升、花青素含量下降及花瓣细胞膜相对透性的上升,从而延长瓶插寿命。
