多胺对月季切花衰老过程中生理生化和瓶插寿命的影响

Treatment with 0.1 mmol/L spermine (Spm) could maintain high contents of reduced sugars and soluble proteins at early stage in cut rose flowers during vase-holding period, in the meantime, the increase in membrane permeability in petals and leaves, the accumulation of MDA in petals, and the ethylene evolution were inhibited. However, spermidine (Spd) did not show remarkable effect.
