Estimation of salt and drought stress in area A, B, C, and P. Ion concentrations (mg/g dry weight (DW)) in (a) soil and (b) leaves taken from areas A, B, and C in the Ein Avdat valley and irrigated controls (area P). (c) ¹³C content, expressed as δ¹³C (‰) was analyzed in the same samples used for ion concentration measurements. Significant (p ≤ 0.05) differences are marked with different letters. The soil and leaf samples were harvested on 13 October 2004.
