Abstract

The aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. Velvet. Hence, an experiment involving the pulsing treatment with gibberllic acid (GA3) at 0, 20, 40 and 60 mg L-1, for 24 hours, and holding them in sucrose at 0, 2 and 3% with 250 mg L-1 of 8- HQS as an antimicrobial agent for all holding treatments was conducted. The study was performed as a factorial experiment based on a randomized completely design (RCD) with three replication for each combination treatment. Applying GA3 pulse treatment alone at all concentrations increased significantly vase life and its effect enhanced with sucrose holding at 2 and 3% compared with control. The effect of GA3 pulsing in increasing of stem relative fresh weight (RFW) and solution uptake (SU) was hastened by sucrose holding treatment at 2 and 3%. Highest amount of flower opening and petal water content during vase life period was observed in 60 mg L-1 of GA3 pulsing and sucrose 3% holding treatment which had been longer flower diameters and greater petals. Gibberellic acid pulsing alone and along with sucrose holding treatment at all concentrations caused to prevention of leaf chlorophyll degradation compared with control. In conclusion, GA3 pulsing at 40 mg L-1 along with sucrose 2% holding treatment had a significant effect on improving vase life and other qualitative attributes of cut rose flower cv. Velvet.
