Influence of pulsing with different chemicals on postharvest life and biochemical constituents of cut roses.

Cut flowers of the rose cultivar Raktagandha were pulsed with sucrose, silver thiosulphate (STS) or silver nitrate (AgNO3) at various concentrations for different durations. Pulsing with 6% sucrose for 12 h, 0.5 mM STS for 45 minutes or 1 mM AgNO3 for 15 minutes improved the vase life and quality of the cut flowers, with STS giving the best results (vase life increased from 7 days in non-pulsed controls to 11.25 days). Increased vase life was associated with a rise in total soluble sugars and the lowest content of total free amino acids content in petal tissues throughout senescence.
