摘　　要：研究含苯甲酸和磷酸二氢钾的保鲜剂对非洲菊切花衰老的影响,以期探索出一种适宜的保鲜剂,解决非洲菊花茎的弯颈问题。结果表明:含适宜浓度的苯甲酸和磷酸二氢钾的保鲜剂明显延长切花保鲜时间,维持切花鲜重,增强水分平衡,降低脯氨酸含量,延缓第二呼吸高峰的到来,解决了非洲菊鲜切花的弯颈问题;其中保鲜剂Ⅳ、Ⅴ(30g·L-1蔗糖+200mg·L-18-羟基喹啉柠檬酸盐+75mg·L-1磷酸二氢钾+40～60 mg·L-1苯甲酸)保鲜效果最好。Effect of preservatives containing benziond acid and KH2PO4 on ageing of cut Gerbera flower was studied in order to explore an appropriate preservative that could overcome neck-bending problem. The results indicated that preservatives containing benziond acid and KH2PO4 prolonged fresh day, maintain fresh weight, improve water balance, reduce proline, delay the second climacteric and settle neck-bending problem. Preservative IV and V （30g· L^-1 sugar＋200mg·L^-1 8-HQC＋75mg·L^-1 KH2PO4 ＋40-60mg· L^-1 benziod acid were the best.
