It has been demonstrated previously that the physiological and molecular analysis of seedlings of the tolerant (Om Rabia3) and susceptible (Mahmoudi) Tunisian wheat genotypes were different at short and long-term response to salinity. In this study, we examined the antioxidant defence system in seedlings of these two cultivars at short-term response to different NaCl concentrations. The findings showed that high salinity tolerance of cv. Om Rabia3, as manifested by lower decrease in its dry biomass, was associated with lower malondialdehyde and hydrogen peroxide contents, lower accumulation of the superoxide (O 2 -) in the roots and the shoots, and also lower decrease in ascorbate content than those in cv. Mahmoudi. Moreover, the expression of some genes coding for antioxidant enzymes such as the catalase, the superoxide dismutase and the peroxidase were enhanced by NaCl stress especially in the salt-tolerant cultivar. In parallel, their activities were increased in response to the same condition of stress and especially in the cv. Om Rabia3. Taken together, these data suggested that the capacity to limit oxidative damage is important for NaCl tolerance of durum wheat.

“…A remarkable increase in the APX activity was observed in more salt-tolerant Beta vulgaris L. (Bor et al, 2003) and Sesamum indicum L. cultivars (Koca et al, 2007). Previous studies with Triticum aestivum L., Oriza sativa L., Zea mays L. evidenced that salt-tolerant genotypes had a more efficient antioxidative system (Sairam et al, 2002;Demiral and Turkan, 2005;De Azevedo Neto et al, 2006).…”

The aim of the current study is to assess the growth response, biochemical changes, photosynthetic pigments content and gas exchanges of physic nut (Jatropha curcas) grown under natural saline conditions. The experiment was arranged in a completely randomized design based on the following soil electrical conductivities: 0.29 dS.m -1 (control), 1.76 dS.m -1 (moderate salt concentration), 2.61 dS.m -1 (high salt concentration), 3.79 dS.m -1 (very high salt concentration). Physic nut plants were kept under saline conditions for 19 days in greenhouse. Plant growth analyses were performed on a weekly basis. Plant biomass allocation was quantified at the end of the experiment. Leaf gas exchange, stomatal conductance, Fv/Fm and quantum yield were quantified 102 days after planting. Photosynthetic pigments, amino acids, proline and carbohydrates in fresh leaf tissue were also quantified. The leaf antioxidant enzymes catalase (CAT) and ascorbate peroxidase (APX) were quantified. Although there was no alteration in biomass allocation, the initial growth of J. curcas was gradually reduced by increasing salt concentration, which was observed through reduced plant height, stem diameter, and total number of leaves. Soil electrical conductivity 3.79 dS.m -1 was lethal to seedlings. Seedlings exposed to salt stress had their photosynthesis, stomatal conductance, transpiration and effective photochemical efficiency reduced, and their catalase and ascorbate peroxidase enzyme activity increased. Amino acids, proline and carbohydrate concentrations increased due to salt stress, whereas there was decrease in the chlorophyll content. J. curcas is sensitive to soil salinity at electrical conductivity levels higher than 1.76 dS.m -1 . To some extent, salinity effects can be relieved by osmolyte accumulation and by greater antioxidant activity; however, these factors were not sufficient to keep plant growth within normal rates.

“…From agricultural perspective, these oxidative stresses are among the most significant factors responsible for substantial losses in crop productivity (Koca et al 2007). The primary effects of abiotic stress is ion imbalance and hyper-osmotic stresses responsible for the induction of molecular network, which in turn activates stress responsive mechanism to reestablish homeostasis through repair mechanism of damaged proteins and membranes (Ahmad et al 2010).…”
