| 摘 要： | 研究了金嘴蝎尾蕉切花最佳采收时期和对其苞片褐变具有良好控制效果的预处理保鲜液及瓶插方法。结果表明: 金嘴蝎尾蕉以中蕾期采收最佳; 整个花枝水平放置, 完全浸泡于500 mg·L - 1 H3BO4或500 mg·L - 1 MgSO4中1 h后, 结合2 mg·L - 1 6-BA + 200 mg·L - 1 Al2 ( SO4 ) 3瓶插保鲜及0.1%聚乙烯醇喷洒花枝, 可显著控制苞片褐变, 保持组织较低水平pH值, 减缓膜透性的上升。其瓶插寿命分别达12 d和11.5 d, 显著高于对照的4 d。

| Abstract: | The optimum harvest time and effective pretreatment solutions and their treatment methods of cut Heliconia rostrata in relation to the control of spath browning were studied. The middle flowering bud stage was determined to be the optimum harvest stage. The whole flower twigs were immersed completely for 1 h in a solution containing 500 mg·L - 1 H3BO4 or 500 mg·L - 1 MgSO4 , then placed in a vase solution containing 2 mg·L - 1 6-BA + 200 mg·L - 1 Al2 ( SO4 ) 3 and finally sprayed with 0.1% polyvinyl alcohol. These treatmentssignificantly controlled the browning of spath tissues of cut Heliconia rostrata, maintained a low pH value and reduced the increase of membrane permeability. After treatments, their vase life were 12 d and 11.5 d, respectively, which was significantly higher than the control (4 d). |
