摘要
郁金香切花在瓶插过程中，自由基清除剂苯甲酸钠（ＳＢ）处理可显著减缓蛋白质含量的下降，降低膜脂过氧化产物ＭＤＡ的积累，维持膜的完整性，减缓膜脂的饱和化趋势，对膜系统有一定保护作用，提高切花观赏品质。而自由基源硫代硫酸钠（Ｎａ＿２Ｓ＿２Ｏ＿３）则加速切花瓶插过程中蛋白质含量的下降，增加ＭＤＡ含量和膜透性的上升幅度，促使膜脂趋于饱和化，加速切花的衰老。
The treatment of free radical scavenge(SB)can slovv down the decline ofsoluble proteins in cutting Tulips during the vase life ,decrease the accumulation ofMDA of the products of membrane-lipid peroxidation,protect the entirety of mem-branes ,slow down the tendency of membranelipid saturation and have some protectiveroles in membrane system thereby to improve the ornamental quality of cutting Tulips.Free radical O_2 source Na_2S_2O_3 can accelerate soluble protein contents to decline duringvase life of cutting Tulips,increase MDA contents and membrane permeation and encor-rage membrane-lipid to become saturation thereby to speed up cutting Tulips senes-cence.
