摘要
以大王龙船花(Ixora chinensis Lamack)切花为试材进行保鲜处理,在添加8-羟基喹啉硫酸盐(8-HQS)100 mg/L的基础上探讨不同质量浓度果糖对大王龙船花切花保鲜效果的影响.结果表明:与对照相比,8-HQS 100 mg/L+果糖20 g/L保鲜液处理可显著延长瓶插寿命3.81 d,提高切花的开花率和可溶性糖的质量分数,使切花的鲜质量、水分平衡值和花瓣质膜透性变化比较缓慢.因而此保鲜液适用于大王龙船花切花的瓶插保鲜,并可提高其观赏价值.
Effects of different fructose concentrations on Ixora Chinensis cut flower preservation were stu- died by adding 100 mg/L of 8 - HQS. The results showed that the preservative solution （8 - HQS 100 mg/L ＋ fructose 20 g/L） could significantly prolong the vase life of cut Ixora Chinensis flower, which could keep 3.81 days more than the control （8 -HQS 100 rag/L）, and it could increase the flowering rate and soluble sugar content, much slow changes of the fresh mass and water balance value, and the relative membrane permeability. Thus, the preservative solution in this study can improve vase preserva- tion life and the ornamental value of cut Ixora chinensis flower.
