| Abstract:
Treatment with a combination of cis-propenylphosphonic acid (PPOH) and  -aminoisobutyric acid (AIB) on the vase life of cut carnation (Dianthus caryophyllus) flowers was investigated.
In both continuous and pulse treatments, the vase life of cut carnation flowers markedly increased when treated with the combination of PPOH and AIB as compared with treatment with each compound alone, and their equimolar combination exerted the highest activity.
The combination of PPOH and AIB was considered synergistic.
When applied as a pulse treatment, the 20 mM equimolar combination was comparable to the 0.2 mM silver thiosulphate used commercially to prolong vase life.
These results show that the combination of PPOH and AIB may be useful in postharvest preservation of cut carnation flowers.
