| Abstract | ||||
| This study was conducted in the laboratory of the Veget. and Flor. Dept., Fac. of Agric., Mansoura Univ. during spring of 2002 and 2003 seasons on the cut rose flowers (Rosa hybrida L.) cv."Eccentric" obtained from a commercial rose farm at EI- Kanater area. It aimed to study the effect of the drinking tap water of Mansoura City and four mineral drinking water types (Aqua, Baraka, Nestle, and Siwa) compared with the distilled water on postharvest keeping quality of cut rose flowers. The results showed that keeping cut rose flowers in distilled water was best for longest vase life, highest water uptake and fresh weight gain of the flowers in addition to the best changes in weight throughout their vase life. Tap and Siwa water types ranked second, followed by Aqua and Nestle, while Baraka water was the least in all parameters. Water analysis revealed that the main effect of water type on vase life and quality of cut roses was related mainly to the total dissolved solids in the water, since the results showed that the lower the total dissolved solids (TDS) in the water, the better was the keeping quality of cut roses and vice versa. It was concluded that the retarding effect of Baraka water on the keeping quality of cut roses might be due to the highest total dissolved solids (TOS), and the harmful effect of the highest sodium (Na +) and bicarbonate (HC03) concentrations in this water type, compared with the other water types. | ||||
