Effet de la température de l'eau sur l'absorption d'eau et la durée de conservation en vase des fleurs coupées.

Effect of water temperature on water uptake and vase life of different cut flowers.

Auteurs : SLOOTWEG G.

Résumé

In the first part of the research the effect of the water temperature on the water uptake of roses has been investigated. After a dry period the most fast water uptake occurred in cold (0 °C) water. The water uptake was slowest in water of 20 °C. The effect of water of 40 °C on the uptake was sometimes as fast as in cold water, sometimes slower than in water of 20 °C. Experiments with gassed and degassed water showed that the extent of saturation of the water with air was responsible of certain differences. Most crops showed the fastest water uptake in cold water, but the size of the effects depended on the crop. Very little effect was found on the length of the vase life and on bud opening.
