摘要/Abstract

摘要： 用50ml·L^-1水杨酸(SA)+2%蔗糖与常用保鲜剂300ml·L^-18羟基喹啉柠檬酸盐(8HQC)+2%蔗糖做对比试验,探讨了SA对玫瑰切花的保鲜效果,结果表明:SA与8HQC效果相似,与去离子水处理对比,两种保鲜剂处理都明显降低了玫瑰切花瓶插期间的呼吸代谢强度,缓解了花朵的水分亏缺,减轻了花朵膜损伤,并提高了切花瓶插期的观赏品质,使玫瑰切花瓶插寿命延长了3d;与8HQC相比,SA提高了切花的观赏性。

关键词: 玫瑰切花, 保鲜机理, 水杨酸, 8-羟基喹啉柠檬酸盐

Abstract: The preserving effect of SA(50 ml·L^-1 SA+2% sucrose) on cut rose was investigated in contrast to the effect of 8-HQC(300 ml·L^-1 8-HQC+2% sucrose ) The results showed that the preserving effects of SA treatment was similar to that of 8-HQC treatment Compared with deionized water treatment,the two preservatives significantly decreased the respiration rate,alleviated the moisture stress and the membrane injure,improved the decorative quality of cut flower in vasing duration and lengthened the holding-vase life for 3 days SA treatment made the cut roses more colorful and ornamental than that 8-HQC treatment.

Key words: Cut rose, Preservation mechanism, Salicylic acid(SA), 8-hydroxyquinoline citrate(8-HQC)
