ABSTRACT
This research investigated the effect of different concentrations of sodium nitroprusside (SNP, a donor of nitric oxide) on the longevity of cut giant chincherinchee (Ornithogalum saundersiae) inflorescences. Postharvest quality of inflorescences was positively affected by SNP treatment. Application of SNP enhanced the vase-life, final fresh weight and diameter of inflorescences. The best quality inflorescences were obtained when the stems held in 100 µmol SNP. These are the first published results that indicate that nitric oxide positively improved the longevity and quality of cut O. saundersiae inflorescences.
