Abstract

The aim of this study was the better assessment of the relationship between postharvest foliar application of gibberellic acid and calcium chloride as anti-senescence agents on improving some qualitative and physiological attributes of cut rose flower cv. Velvet. Hence, an experiment was conducted as the foliar treatment of cut stems with gibberllic acid (GA3) at 0, 0.5, 1 and 1.5 mM, and calcium chloride (Ca) at 0, 5, 10 and 15 mM, as the cut stems were held in sucrose solution at 0 and, 2 % with 250 mg.L-1 of 8- HQS as an antimicrobial agent for all holding treatments. The study was performed as a factorial experiment based on a completely randomized design (CRD) with three replication for each combination treatment. Different concentrations of GA3 and CaCl2 increased the vase life of "Velvet" cut rose. The longest vase life (17.8 days) was observed in the combination of GA3 1mM with calcium chloride 15 mM concentrations. The effect of GA3 postharvest foliar application in increasin

Conclusion

In conclusion, the effect of GA3 and calcium in extending vase life of cut rose stem was synergistically, however the concentrations of 1.5 mM of GA3 with calcium chloride 15mM was the most effective postharvest foliar treatment in extending vase life by improving water balance of cut rose stem cv velvet.
