Abstract: 
The effect of an increasing NaCl salinity on CO2 assimilation and on the distribution of 14C in various chemical fractions of young wheat plants was studied. Increasing salinity restricted growth and in particular 14CO2 assimilation being measured at the end of the experimental period. Correspondingly, the amounts of 14C found in the various chemical fractions (amino acids, organic anions, carbohydrates, protein, lipids, insoluble residue) were decreased with an increase in salinity. The relative distribution of 14C in the chemical fractions also was affected by salinity. At low salinity level a relatively low 14C concentration was found in the low molecular fractions, while the high molecular fractions showed a relatively high 14C concentration. At high salinity level this tendency was weak. Increasing salinity had no major impact on the nutrient concentration (N, P, K, Ca, Mg) in the shoots, whereas the concentration of Na and especially of Cl was remarkedly raised. This excessive Na and Cl concentrations in the shoots apparently result in the yield depression.
