麦瓶草护绿研究

［目的］研究麦瓶草的护绿方法，为开发切实可行的麦瓶草产品提供科学依据和理论指导。［方法］以麦瓶草为材料, 采用碱性溶液热烫法和金属离子置换法处理，并测定处理后麦瓶草的外观色泽等级与叶绿素含量。［结果］结果表明： 碱性溶液热烫法护绿效果较差，各因素影响的显著性顺序为热汤温度〉热烫时间〉pH，其中热烫温度为极显著，热烫时间为显著，最佳组合为92 ℃、4.5 min、 pH值 7.5；金属离子置换法护绿效果好,各因素影响的显著性顺序为Zn^2＋〉Cu^2＋〉Mg^2＋，其中Zn^2＋和Cu^2＋的影响为极显著，最佳组合为Zn^2＋200 mg/L、Cu^2＋100 mg/L、Mg^2＋200 mg/L。结论］从处理后麦瓶草的外观与叶绿素含量角度来看，金属离子置换法明显优于碱液热烫法。
