Abstract

Keeping anthurium cut flowers under 15oC leads to chilling damage and reduction in flower Vase life. In this research, the effects of postharvest GABA treatments (0, 1 and 5 mM) on Vase life, membrane stability, spathe browning, antioxidant enzymes activity (CAT, SOD), and MDA content during 10 days' storage at 5 and 10 oC were studied. The results revealed that the longest Vase life was observed in 1 mM GABA in 10 oC. Untreated flowers showed the least membrane stability and the highest MDA content in chilling temperatures. SOD activity was increased using 5 mM GABA. The flowers treated with 1 mM GABA had more CAT activity. GABA treatment had no effect on spathe browning. Finally, it can be concluded that both concentrations of GABA (1 and 5 mM) were effective to induce chilling resistance in anthurium cut flowers.
