All cut flowers are destined to die, and the challenge for post-harvest researchers is to slow the processes controlling flower death to enable cut flowers to reach distant markets with a display life. Nitric oxide (NO), provided by the fumigation from sodium nitroprusside (SNP) on delaying senescence in gladiolus cultivar Snow Princess in relation to physiological and biochemical parameters and expression of various senescence associated genes (SAGs). Vase life of flower spikes was significantly increased and fresh weight was retained for longer duration by treatment with NO than control...
