[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.caryophyllus 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 content of MDA in the period of cut flower of D.caryophyllus in vase.VC could delay the aging of cut flower of D.caryophyllus.[Conclusion]The optimum concentration of VC in preservative solution was 200 mg/L.
