摘  要:
以芍药‘春晓’(Paeonia lactiflora ‘Chunxiao’)的切花为试验材料,采用室内瓶插的方法,在基本瓶插液(3%蔗糖+200mg/L8-羟基喹啉+150mg/L柠檬酸)中分别添加不同浓度赤霉素、青霉素,通过对其外部形态和衰老过程中生理生化指标的测定,探讨了赤霉素、青霉素对芍药切花采后瓶插品质的影响。结果表明,适宜浓度的赤霉素、青霉素可有效提高切花的SOD、CAT活性,降低O2-生成速率、MDA含量,减少活性氧对切花的伤害;改善切花的水分平衡值,降低脯氨酸含量,减少水分胁迫对切花造成的伤害;增加可溶性蛋白质含量,为切花提供能源物质,从而延缓衰老,延长瓶插寿命,改善切花瓶插期间的观赏品质。青霉素100mg/L处理的效果最佳,瓶插寿命比对照延长2.5d。

摘  要:
Cut Paeonia lactiflora 'Chunxiao' flowers were hold in different solutions,which added different concentrations of plant growth regulators GA,penicillin into basic preservative(3%S+200mg/L8-HQ+ 150mg/LCA).Effects of GA and penicillin on floral appearance and physiology biochemical characteristics of cut peony flowers were investigated during vase-holding period.The results showed that treatments with suitable concentration of GA or penicillin could effectively increase activities of SOD and CAT,decrease content of malonyldiadehyde,free proline and the production rate of superoxide radical,enhance the content of soluble protein,afford energy resource,and improve water balance of cut peony flowers.The vase life was prolonged through reducing the harm of active oxygen and scarce of water on cut peony flowers.The treatment with 100mg/L concentration of penicillin had the best effect,which prolonged vase life of cut peony flowers 2.5 days.
