摘要
以马蹄莲切花为试材,比较含水杨酸(SA)的保鲜剂与含AgNO3和6-BA的2种传统保鲜剂在维持切花瓶插寿命、水分平衡值、花枝鲜重、丙二醛含量、相对电导率等指标的作用效果。结果表明:3种保鲜剂均能延长切花寿命,降低苞片中丙二醛的积累,减慢细胞膜的损伤速度,但以0.5%蔗糖+0.1%Ca(NO3)2+50 mg/L SA最优。
In this experiment, freshly harvested cut（Zantedeschia aethiopica ） were treated with preservative ingredients containing salicylic acid and traditional preservative ingredients containing AgNO3 or 6-BA, and then the preservation effects was compared through studying on keeping water balance, fresh weight, rnalondialdehyde（MDA） content, relative conductivity and so on. The results indicated that three preservative ingredients could prolong vase life of cut flow- ers, reduce MDA content of bracteole, and slower damage speed of cytomembrane, but the preservative ingredients conraining 0. 5% Sucrose, 0.1% Ca（NOa ）2 and 50 mg/L salicylic acid was optimum.
