Na+ concentrations in both the salt species were 0, 50, 100 and 200 mM. No interaction between salts and concentration was observed for leaf extension growth of all leaves. It was also observed that NaCl treated leaves 9 were significantly shorter than Na2SO4. In each leaf as Na+ concentration increased leaf extension growth decreased. However, the difference in treated plants was non-significant. A drastic reduction in leaf extension growth was observed in 200 mM Na+ concentration from leaf 4 to 6. For leaves 7, 8, 9 and flag leaf, leaf extension growth was not observed in 200 mM Na+ concentration because it suppressed the growth and the plants died earlier.]]>Bernstein, L., 197513295312Food and Agriculture Organization, 1978131216Food and Agriculture Organization, 1980Glass, A.D.M. and M.Y.
