Impact of exogenous ABA (50 µm) and fluridone (FLU) application on total leaf ABA concentration, water content (WC) and leaf stomatal conductance (gleaf) in seedlings of Atriplex halimus issued from a coastal site (Monastir) or an inland area (Sbikha) and exposed for 10 d to control nutrient solution or to a nutrient solution containing 40 or 160 mm NaCl or 15 % PEG

Measurements were performed on fully expanded leaves. Each value is the mean of six replicates ± s.e. of the means. For a given parameter and a given time, values sharing a common superscript letter are not significantly different at P < 0·05.
