Abstract
In a micro-plot experiment it was observed that free proline accumulation in barley and wheat crops increased with the salt stress. But in sensitive strains of both the crops it did not accumulate in accordance with the preceding values after their tolerance limit and at this point yield of barley was reduced by 25.8% and wheat by 23.2% over control while significant yield reductions were not observed with tolerant strains. Proline accumulation was also found to be related to tissue K/Na ratio and the critical limits of this ratio were observed between 0.60 and 0.34 for barley and 4.2 and 1.4 for wheat.
