Leaf water status, proline and soluble sugars in Smirnovia iranica (Sabeti) plants under habitat conditions



An experiment was carried out to investigate the effect of progressing water deficit stress on leaf water relation parameters and compatible solutes at different phenological stages. Completely randomized design including four phenological stages (as drought stress treatments) was used. Each treatment had five replicates. Variables measured were osmotic potential (&PsiS), relative water content (&thetaL), total osmotic adjustment (TOA), proline and total soluble sugar (TSS) content. Data collected were analyzed using analysis of variance (ANOVA) at significance level of P < /em>
