Abstract
The effect of sodium accumulation on growth and production of rose ‘Avalanche’ was evaluated in a trial in stone wool with full recirculation of drainage. Three concentrations ranging from ca 1.5 to 12 mmol/l sodium at equal and with rising EC respectively were assessed. Production was significantly lower at 12 mmol/l and equal EC, but production was not lower when EC increased together with Na. The effect is likely due to the limited K availability at the equal EC treatment. The uptake of Na by rose is exceptionally low; only 0.4-1.4% of the prevailing Na concentration in the root zone. Based on the results of this test, the maximum above which alternative measures are required can be increased to 8 mmol/l. However, since the intake of Na is exceptionally low, the need for high-quality water for roses remains.
