Description 467-475
Gladiolus is an important commercial cut flower of emerging floriculture industry. The prime concern in
commercialization is postharvest management of flowers as flowers are biological systems that perish after harvest. Among
different chemicals used to improve vase life of gladiolus, nitric oxide has emerged as potent signaling molecule that can
delay senescence and improve post harvest life of flowers. Here, we studied the potential of sodium nitroprusside (SNP) as
pulsing solution on post harvest quality of gladiolus. Spikes of gladiolus were harvested at tight bud stage and pulsed for
20 h with SNP solutions of different concentrations and various physiological parameters were recorded to evaluate the
keeping quality. The pulsing solution of SNP @200 mg L-1 with sucrose and aluminium sulphate significantly improved the
vase life whereas pulsing with SNP @400 mg L-1 adversely affected the quality parameters. Spikes pulsed with SNP
@200 mg L-1 supplemented with sucrose and aluminium sulphate had higher membrane stability index, relative water
content, sugar content, protein content antioxidant enzymatic activity and lower TBARS content as compared to control
supporting improved postharvest quality. Thus, sodium nitroprusside @200 mg L-1 with sucrose and aluminium sulphate
could be used as pulsing solution to improve the postharvest quality of spike.
