It is well known that potassium (K+) can be replaced by sodium (Na+) to a great extent in sugar beet (Beta vulgaris). However, the possible extent of substitution is limited also in sugar beet. It was not clear which process limits the substitution of K+ by Na+ in young sugar beet. It is known that K+ is required for the processes of transpiration, growth, and protein synthesis. The aim was to find out which process is most sensitive due to the substitution of K+ by Na+. Therefore, sugar beets were grown at various substitution levels (0.25%, 25.00%, 50.00%, 75.00%, 97.50%, 98.75%, and 99.75% substitution). The sum of supplied K+ and Na+ concentrations was kept constantly equal at the level of adequate K+ nutrition of 4 mM. The approach exc...
