EFFECT OF EXOGENOUS BACTERIAL CONCENTRATIONS ON WATER RELATIONS OF CUT ROSE FLOWERS - I BACTERIA IN THE BASIN WATER |
| Authors: | W.G. van Doorn, Y. de Witte, B.C.H. Waltmann |
| Abstract:
Roses (var. Sonia) were stored for 3 days at 5°C in dark, in water containing various concentrations of bacteria (1.1x102 up to 1.7x107 per ml). The bacteria in the water mainly originated from rose stems that had been stored prior to the experiment. After the 3 days of storage, the roses were transferred to a climate chamber (20°C, 60% r.h., 15 μE/m2/s) and placed in bottles filled with tap water. The previous exposure to even high bacterial numbers did not influence vase life nor water uptake of the roses. | |
