摘　　要：[目的]探究抗坏血酸对康乃馨切花抗衰老的影响。[方法]以康乃馨切花为材料,不同浓度VC保鲜液进行瓶插试验,保鲜期间测定切花瓶插寿命、水分平衡、过氧化物酶(POD)和过氧化氢酶(CAT)活性、丙二醛(MDA)含量。[结果]VC能增强康乃馨吸收保鲜液的能力,增强CAT和POD活性,降低MDA含量,延缓其衰老。[结论]200 mg/L VC对康乃馨切花的保鲜效果最好。[ Objective ] To study effects of antiscorbutic acid on anti senescence of cut flower of Dianthus caryophyllus. [ Method ] With the cut flower of D. caryophyllus as material, the preservation solution with different concentrations of Vc was tested. The flower＇ s lift and water balance, activity of peroxidase（POD） and catalase （ CAT）, and malondiadehyd （MDA） content of cut flower of D. caryophyUus were tested. [ Result] The Vc could enhance the absorbency of cut flower of D. caryophyllus, increase the activity of CAT and POD, and decrease the con- tent of MDA in the period of cut flower of D. caryophyUus in vase. Vc could delay the aging of cut flower of D. caryophyUus. [ Conclusion] The optimum concentration of Vc in preservative solution was 200 mg/L.
