多胺对月季切花衰老过程中生理生化和瓶插寿命的影响

EFFECTS OF POLYAMINES ON BIOCHEMICAL AND PHYSIOLOGICAL CHANGES AND VASE LIFE OF CUT ROSE (ROSA CHINENSIS JACQ. CV. BELLAMIE) FLOWERS DURING SENESCENCE

摘要:

精胺处理可保持月季切花瓶插前期花瓣还原糖和蛋白质的较高水平、减缓花瓣和叶片细胞膜透性的增加、减少花瓣MDA的积累以及降低乙烯释放速率,这与精胺处理后月季切花瓶插寿命提高相一致；但亚精胺处理对月季切花瓶插寿命和改善观赏品质无明显影响。

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.
