Serpentine soils are dry and contain rather high levels of nickel (Ni).To obtain a better understanding of drought tolerance by Ni in serpentine plants, a hydroponic trial was designed to compare the effects of Ni on growth factors, Ni uptake or translocation and some physiological parameters in the serpentine plant, Fortuynia garcinii (Burm.f.), under PEG simulated drought stress (3 levels). A...
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...
The effect of optimal and supra-optimal concentrations (0, 250, 500 and 750 mM) of NaCl on the growth, chlorophyll, soluble carbohydrate and proline content, ion concentrations and antioxidant enzyme defence of Sesuvium portulacastrum was studied. A significant increase in growth and tissue water content was observed in the shoots exposed to 250 mM salt. Minimum damage to the membrane in terms ...
