Abstract

The effects of pH adjustment of distilled, rain and tap water on the vase life and postharvest changes of ‘Christian Dior’ cut roses were studied. The pH of holding water was adjusted to 4, 5, 6, 7 and 8 with citric acid and/or potassium hydroxide as necessary. The results showed that rose vase life tended to increase as the pH was lowered. The optimum pH of distilled and rain water was 4 while the pH of tap water was 5. Lowering the pH by citric acid reduced blueing and bent neck and increase fresh weight, water conductivity and water consumption of cut roses.
