Postharvest life of cut gerbera (gerbera jamesonii) flowers as affected by salicylic acid, citric acid and ascorbic acid

摘要

Gerbera jamesonii from Asteraceae family is important cut flowers. Extending the vase life of gerbera cut flower was studied by three concentrations of salicylic acid, citric acid and ascorbic acid (50, 100 and 200 mg l-1). Results revealed that the maximum vase life (11.31 days) was achieved in 100 mg l-1 of citric acid. The vase life of control cut flowers was 5.80 days. Other measured characters such as loss of fresh weight, dry matter percentage, brix degree, flower diameter decreasing index, bacterial population in vase solution and petal carotenoid were affected by these treatments.
