Abstract

Seedings of Vicia faba were grown for four weeks at two different light intensities (55 and 105 watts per square meter) in a saline (50 millimolar NaCl) and nonsaline nutrient solution. NaCl salinity depressed growth and restricted protein formation, CO(2) assimilation, and especially the incorporation of photosynthates into the lipid fraction. Conversion of photosynthates in leaves was much more affected by salinity than was photosynthate turnover in roots. The detrimental effect of NaCl salinity on growth, protein formation, and CO(2) assimilation was greater under low than under high light conditions. Plants of the high light intensity treatment were more capable of excluding Na(+) and Cl(-) and accumulating nutrient cation species (Ca(2+), K(+), Mg(2+)) than plants grown under low light intensity. It is suggested that the improved ionic status provided better conditions for protein synthesis, CO(2) assimilation, and especially for the conversion of photosynthates into lipids.
