Effect of preservative chemicals on post-harvest behaviour of cut rose cv. Etoile De France.

Blooms of "Etoile De France" a cultivar of rose were treated with vase-solutions containing several proven floral preservative chemicals (200 ppm 8-hydroxyquinoline sulfate (8-HQS), 100 ppm Silver nitrate, 0.5% Aluminium sulfate, 300 ppm 8-hydroxyquinoline citrate (8-HQC) and 200 ppm Nickel chloride) along with 4% sucrose. Distilled water was used as the control. The highest water uptake (9.50 g) was recorded with distilled water. The total water loss was recorded maximum (9.97 g) when placed in distilled water, however, it was minimum (2.96 g) with the vase solution containing sucrose + Silver nitrate. The enhancement in the fresh weight was recorded highest (0.70 g) in sucrose + Silver nitrate treated vase solution. Holding solution containing sucrose + 8-HQC was proved beneficial for the earliest opening of the flowers (1.00 day) and longer duration of prime beauty (3.50 days). The "bent neck" was recorded minimum with sucrose + Aluminium sulphate. However, the vase-solution treated with sucrose + 8-HQC showed the longest postharvest life (4.50 days) of cut rose flowers.
