摘　　要：为明确适宜于香石竹切花保鲜的苯甲酸钠浓度,采用在基础瓶插液中分别添加150、200、250、300 mg/L苯甲酸钠的保鲜液对香石竹切花进行瓶插处理,每2 d取样测定切花形态指标与生理生化指标。结果表明:添加不同浓度苯甲酸钠的保鲜瓶插液均能延长香石竹切花的寿命,改善切花水分状况,提高切花品质;与对照相比,苯甲酸钠质量浓度为150 mg/L和200 mg/L的瓶插液对香石竹切花保鲜效果差异均不显著,而苯甲酸钠质量浓度为250 mg/L和300 mg/L的瓶插液对香石竹切花保鲜效果差异均显著(P<0.05)。综合比较,苯甲酸钠质量浓度对香石竹切花保鲜效果排序为250 mg/L>300 mg/L>200 mg/L>150 mg/L。本研究结果可为延长香石竹切花瓶插寿命及保鲜剂研究提供理论依据。In order to clarify the appropriate concentration of sodium benzoate suitable for the preservation of cut carnation flowers,150,200,250,300 mg/L sodium benzoate preservative solution were added to the base vase solution to treatment cut carnation flowers.The morphological and physiological and biochemical indicators of cut flowers were measured every 2 days.The results showed that the addition of different concentrations of sodium benzoate in vase could prolong the vase life of cut carnation flowers,improve the water status and the quality of cut flowers.Compared with the control,there was no significant difference in the preservation effect of vase solution with 150 mg/L and 200 mg/L sodium benzoate on cut carnation flowers,while there was a significant difference in the preservation effect for 250 mg/L and 300 mg/L sodium benzoate solution(P<0.05).Comprehensive comparison,the order of the preservation effect of sodium benzoate mass concentrations on cut carnation flowers from high to low was 250,300,200,150 mg/L.
