摘　　要：[目的]探究食用色素对月季的安全性及对其切花衰老的影响。[方法]在前期使用食用色素获得染色月季的基础上,对染色月季的瓶插衰老和安全性相关指标进行观察和检测。[结果]在温度(20±2)℃、湿度(50±5)%的条件下,染色月季与未染色月季切花的瓶插寿命均为9~10 d,无显著差异。食用色素染色月季切花的抗氧化酶SOD和CAT活性虽然低于未染色月季切花,但相差较小,其显著高于专业染色剂处理的月季切花的抗氧化酶活性。食用色素染色月季切花瓶插液中菌落数目显著低于专业染色剂月季切花瓶插液,且染色花瓣中铅、汞、砷的含量与未染色处理无显著差异,远低于国标要求。[结论]食用色素对月季切花的瓶插寿命和衰老影响较小,且食用色素染色月季切花的重金属含量符合国标要求,安全性有保证。[Objective]To explore the safety of edible pigments on roses and their effects on senescence of cut roses.[Method]On the basis of using food pigments to obtain dyed roses in the early stage,the indexes related to bottle aging and safety of dyed roses were observed and detected.[Result]The results showed that under the conditions of temperature(20±2)℃and humidity(50±5)%,the bottle life of both dyed and un-dyed rose cuttings was about 9-10 days without significant differences.The antioxidant enzymes SOD and CAT activities of food color dyed rose were lower than those of unstained rose,but the difference was small;they were significantly higher than those of professional dye treated rose.The number of bacterial colonies in the bottle insert of food coloring dyed rose was significantly lower than that in the bottle insert of professional dyed rose,and the content of Pb,Hg and As in the dyed petals was not significantly different from that in the unstained ones,which was much lower than the national standard.[Conclusion]The food coloring did not affect the life span and aging of cut flowers in vase,and the heavy metal content of food coloring dyed cut flowers complied with the national standard,which proved its safety.
