Abstract

In this study, effect of foliar application of 5-sulfosalicylic acid and malic acid in extending the vase-life of Eustoma grandiflorum Mariachii. cv. white flowers was investigated. The treatments included malic acid at three levels (1.5, 3 and 5 mM) and 5-sulfosalicylic acid at three levels (0.5, 1 and 1.5 mM) and distilled water as a control. Results showed 5-sulfosalicylic acid and malic acid increased chlorophyll and carbohydrate content, while descreasing ACC-oxidase activity and delay of senescence and peroxidation of lipids. In general, spraying 5-sulfosalicylic acid and malic acid at level of 1.5 and 5 mMare recommended for increasing of vase life of cut Eustoma grandiflorum flowers.
