Open publisher page 3 citations

Abstract

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.
