摘要: 蒟蒻薯(Tacca chantrieri Andre)是观赏价值较高的稀有黑色切花,但瓶插寿命较短,对其进行保鲜研究具有重要意义。用蔗糖、8–羟基奎宁(8-HQ)和柠檬酸按三因素二水平的正交设计配制瓶插保鲜液,通过观察切花形态变化,测定瓶插寿命和鲜样质量,研究瓶插液的保鲜效果。结果表明,与对照相比,各处理均能不同程度地延缓切花衰老,其中A处理,即2%蔗糖 + 100 mg · L-1 8-HQ + 200 mg · L-1柠檬酸 + 50 mg · L-1 6-BA + 100 mg · L-1 K2HPO4处理效果最好,花枝寿命和花须寿命分别比对照长17 d和14 d,是蒟蒻薯切花较好的瓶插保鲜配方。

Abstract: Tacca chantrieri is a precious ornamental cut flower with rare black color. Retaining its freshness is significant importance because of its short vase life. The preservative solution effect on cut flower of Tacca chantrieri treated with vase preservative solutions comprised of sucrose,8-hydroxy- quinoline(8-HQ),and citric acid(CA)was studied. This solution prepared by using orthogonal design method of three factors and two levels. The shape of cut flower,the life of vase and the weight of fresh sample were analyzed. The results showed that all treated solutions could significantly prolong the vase life of cut flowers than the control. Treat A(2% sucrose + 100 mg · L-1 8-HQ + 200 mg · L-1 CA + 50 mg · L-1 6-BA + 100 mg · L-1 K2HPO4)has the most effective results,which delayed the life of branch and fibrous bract 17 d and 14 d,respectively. It is the most efficient vase preservative formula for cut flower of Tacca chantrieri.

Key words: Tacca chantrieri, cut flower, preservative solution, preservative effectiveness
