水杨酸在切花菊保鲜中的应用

目的]研究水杨酸（SA）对切花菊衰老的影响。方法]采用不同保鲜剂（B1：3％蔗糖＋50mg／LSA；B2：3％蔗糖＋100mg／LSA；B3：3％蔗糖＋150mg／LSA；CK：3％蔗糖＋蒸馏水）处理切花菊，测定各处理切花菊衰老过程中鲜重、水分平衡值、糖及蛋白质含量的变化。结果]B2、B3处理切花菊鲜重和蛋白质含量均极显著高于CK；B1、B3处理切花菊水分平衡值极显著高于CK；]B1、B2处理切花菊糖含量极显著高于CK。结论]sA可有效减缓切花菊水分、糖和蛋白质损失，保鲜剂B2（3％蔗糖＋100mg／LSA）和B3（3％蔗糖＋150mg／LSA）的保鲜效果较好。

Application of Salicylic Acid in Fresh-keeping of Cut Chrysanthemum

Objective] The aim was to study the effect of salicylic acid(SA) on aging of cut chrysanthemum.Method] The cut chrysanthemum was treated by different preservatives(B1:3% sucrose+50 mg/L SA;B2:3% sucrose+100 mg/L SA;B3:3% sucrose+150 mg/L SA;CK:3% sucrose+ distilled water),the change of fresh weight,hydrologic balance value and contents of sugar and protein of the cut chrysanthemum in their aging process were detected.Result] The fresh weight and protein content of cut chrysanthemum in treatments B2 and B...
