Abstract

Chilling damage under 15ºC in anthurium cut flowers reduces the vase-life, quality and marketability of the product. In the present experiment, GABA postharvest treatment (0, 1 and 5 mM) was studied on the vase-life, total soluble solid (TSS), H2O2 content, proline content, spathe browning, catalase and superoxide dismutase enzymes activity of Anthurium andraeanum 'Sirion' during 10 days of storage at 10ºC and 5ºC. The results revealed that 1 mM GABA treatment at 10ºC was the treatment of choice considering the vase-life. GABA treatment had no special effect on reducing the browning incidence. GABA at 5 mM increased the SOD activity. Furthermore, GABA reduced H2O2 levels compared to control untreated flowers. Moreover, under chilling stress, proline was the highest with GABA treated flowers. One mM treated GABA treatments hold higher catalase activity. The highest TSS belonged to 5 mM GABA under 5ºC.
