✦ Synopsis
The effect of salinity (50 mM NaC1) on wheat photosynthesis, transpiration, growth and grain yield of plants growing in sand irrigated with nutrient solutions containing different nitrogen sources (NO~-or NH4 +) is described. At this salinity level, little yield decrease was observed although vegetative growth was affected to a larger extent. Salinity induced enhanced translocation of assimilates from the flag leaf to developing grains. No significant differences were observed between saltstressed plants irrigated with either ammonium or nitrate. The nitrogen source mainly affected kernel growth rate and final weight.
