STRUCTURAL AND ENVIRONMENTAL FACTORS AFFECTING THE POSTHARVEST LIFE OF CUT ROSES |

| Abstract:
Aspiration of air into the stems of mildly dehydrated cut rose flowers (Rosa hybrida L.) significantly reduced their hydraulic conductivity. Under normal vase-life conditions, 'Sonia' roses rehydrated rapidly, and 'Cara Mia' roses failed to rehydrate. The rehydration ability was correlated with conductivity of the embolized basal stem segment. In a stressful postharvest environment, neither cultivar was able to rehydrate unless the stems were recut under water. The data suggest that inspired air is the major factor affecting the initial rehydration of cut roses. | |
