摘　　要：以非洲菊(Gerbera jamesonii Bolus)鲜切花珍爱为试材,研究不同预处理液与瓶插保鲜液组合对丙二醛含量(MDA)、细胞膜透性、细菌含量及瓶插寿命的影响。结果表明,非洲菊切花经预处理液处理12 h后,MDA含量、细菌菌落数均显著低于对照(去离子水),且预处理能降低细胞膜的相对透性。非洲菊切花在瓶插处理期间MDA含量及细胞膜透性出现先下降后上升的变化趋势,瓶插14 d时达到最大值。花茎及瓶插液的细菌菌落数在瓶插过程中呈逐渐上升趋势,鲜花营养剂和免切通用鲜花营养液2种瓶插液表现了较好的抑菌效果。保鲜效果最佳的保鲜剂组合为可利鲜专业1号醒花液+鲜花营养剂,该处理可显著延长切花的瓶插寿命,其预处理及瓶插期间MDA含量、细胞膜透性和细菌菌落数的累积值均显著低于对照。Using Gerbera jamesonii Bolus Zhenai as the sample,the effects of the combination of preprocessing solution and vase pres-ervation solution on malondialdehyde(MDA)content,cell membrane permeability,bacteria content and vase life of Gerbera jamesonii fresh-cut flowers were tested.The results showed that after 12 h treatment with preprocessing solution,MDA content and colony form-ing units(CFU)of Gerbera jamesonii fresh-cut flowers were significantly lower than those of the control group(deionized water)and preprocessing could decrease relative permeability of cell membrane in petals.During vase treatment,MDA content and membrane permeability of Gerbera jamesonii fresh-cut flowers decreased firstly and then increased,reaching the peaks at 14 d.CFU in anthocau-lus and vase preservation solution increased gradually throughout the vase treatment.Vase preservation solutions of Chrysal cut flower food and Oasis flower food-liquid showed relatively good antibacterial effects.Chrysal professional 1 and Chrysal cut flower food were the solution combination with the best preservation effect,which could prolong vase preservation life of cut flowers,significantly.Cu-mulative values of MDA content,membrane permeability and CFU in preprocessing and vase preservation period were significantly lower than those of the control group.
