Ionic, not the osmotic component, is responsible for the salinity-induced inhibition of greening in etiolated wheat (Triticum aestivum L. cv. Mv Beres) leaves: a comparative study.

ABSTRACT:

Main conclusion

Greening was partially (in 300 mM NaCl, CaCl₂, 600 mM KNO₃ or KCl) or fully inhibited (in 600 mM NaCl, NaNO₃ or NaCl:KCl) by the ionic and not the osmotic component of salinity. Although high soil salinity is an increasing global problem, not much is known about how direct exposure to salinity affects etiolated leaves of seedlings germinating in the soil and then reaching the surface. We investigated the effect of various salt treatments on the greening process of leaves in 8- to 11-day-old etiolated wheat (Triticum aestivum L. Mv. Béres) seedlings. Etiolated leaf segments pre-treated on different salt (600 mM NaCl:KCl 1:1, 600 mM NaCl, 600 mM KCl, 600 mM NaNO₃, 600 mM KNO₃, 300 mM KCl, 300 mM NaCl or 300 mM CaC
