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?H2O + 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。
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?H2O + 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.
