Title Osmolyte concentrations in Atriplex halimus L. and Atriplex canescens (Pursh) Nutt. adapted to salinity and low temperature (Chenopodiaceae)
Source Anales de Biologia
Abstract We investigated the effects of cold (freezing) tolerance for Atriplex halimus and Atriplex canescens (Chenopodiaceae) from different locations in Algeria. Plants were grown in pots of soil for three months, after a one-month acclimation period, the cold tolerance was determined, in leaf electrolyte leakage assays. For A. halimus, the effect of increased soil salinity (addition of NaCl) on tolerance was determined and the cold-acclimated plants were compared with those grown in saline nutrient solution, in relation to leaf levels of cations and organic osmolytes. There was significant correlation between the cold tolerance and the leaf tissue water concentrations of Na and Na+K. Here we relate changes in osmolyte concentration under cold acclimation/soil salinisation.
