Effects of retail hydration on water uptake and quality of 'Madame Delbard' roses after long term transport.

'Madame Delbard' roses were imported to the USA from Colombia after a 5-6 day transport time. Stems were hydrated with a commercially available hydration solution for one hour to simulate retail conditions then placed in a floral preservative. Water uptake was monitored during the hydration period and every 24 hours until stem death. A non-hydrated control was also included. Stems were maintained at 21 deg C at a light level of 10 micro mol m-2 s-1 (12 hours/day). Hydration solution temperatures of 2 deg C and 43 deg C were also examined. No effect of hydration was found on daily water uptake. Hydrating stems increased cumulative water uptake by 19% compared to non-hydrated stems, but was not significantly different. This increase in water uptake did not relate to vase life or quality. Stems lasted an average of 9 days and there were no differences in flower opening or leaf quality. Stems took up 40% more solution when hydrated at the higher temperature after the first hour but no differences were found in cumulative water uptake, vase life or quality.
