Abstract
The major problem of cut Curcuma sp. is the relatively short postharvest due to the rapid wilting of the coma bracts, thus the objective of this present study was to study the effect of anti-transpirant on postharvest quality of Curcuma 'Laddawan' (patumma) inflorescence. Postharvest quality and display life of the inflorescence were determined at 25°C. Application of 5 and 10 μM abscisic acid (ABA) and methyl jasmonate (MeJA) reduced transpiration rate but did not delay loss of fresh weight. Patumma inflorescences held in 5 μM of MeJA solution increased water uptake and transpiration rate as compared to others. However, neither ABA nor MeJA prolonged the vase life of inflorescences.
