摘　　要：芳香是花卉重要的观赏性状和品质特征,调控花卉芳香成分的挥发能有效促进芳香植物的合理应用,并提高其经济价值。为系统地研究外源植物花香调节剂处理对植物花香性状的影响,研究以地毯蓝矮牵牛为试验材料,选用正钒酸钠、槲皮素、甘草酸分别喷施盛花期花朵,同时以喷施清水为对照,并采用顶空固相微萃取和气相色谱-质谱联用技术对处理前后的花朵进行挥发成分的测定。结果表明,喷施正钒酸钠、槲皮素和甘草酸后地毯蓝矮牵牛花朵总挥发量分别降低93%~98%、92%~94%和72%~93%;对照组中地毯蓝矮牵牛主要挥发成分为苯甲酸甲酯,正钒酸钠、槲皮素和甘草酸处理后主要挥发成分则分别改变为2-甲基丁酸甲酯、β-蒎烯和乙酸乙酯等。研究所选用的3种外源植物花香调节剂对地毯蓝矮牵牛的主要挥发物苯甲酸甲酯的挥发具有明显的抑制作用,而且能够通过改变挥发物的主要组成成分从而改变矮牵牛的花香性状,该喷施花香调节剂的方法明显降低了矮牵牛浓郁花香,适宜在园艺观赏等应用方面推广。Aroma is an important ornamental trait and quality characteristic of flowers, also regulating volatilization of aromatic components can effectively promote rational application and increase the economic value of aromatic plants. In order to systematically study the effects of application of exogenous floral fragrance regulators on the aromatic traits of plants, in this study, Carpet Blue Petunia hybrida was used as the material. sodium vanadate, quercetin and glycyrrhizic acid were selected to spray on the blooming flowers with clear water as control, then the volatile components of Carpet Blue Petunia hybrida flowers before and after treatments were determined by headspace solid phase microextraction and gas chromatography-mass spectrometry. The results showed that after spraying sodium vanadate, quercetin and glycyrrhizic acid, the total volatilization of Carpet Blue Petunia hybrida flowers decreased by 93%-98%, 92%-94% and 72%-93%, respectively. The main volatiles of the control group Carpet Blue Petunia hybrida was methyl benzoate. In the treatments of sodium vanadate, quercetin and glycyrrhizic acid, the main components were changed to methyl 2-methylbutyrate, β-pinene and ethyl acetate, respectively. In short, application of the three floral fragrance regulators in this study significantly inhibited the volatilization of methyl benzoate,the main volatiles of Carpet Blue Petunia hybrida, and could change the aromatic traits of Petunia hybrida by changing the composition of the volatiles. The method of spraying flower fragrance regulator could significantly reduce rich flower fragrance of Petunia hybrida, and was suitable for popularization in horticulture, ornamental and other applications.
