“…Salt (NaCl) stress triggered the accumulation of compatible osmolytes like proline and GB in the present study, which corroborated the findings by Khan et al (2012), Khan et al (2009) and Ahmad et al (2014) in different plant species. In NaCl-stressed Morus alba (Ahmad et al 2010) and Vigna radiata , improved growth has been attributed to their potential to accumulate a significant amount of proline and GB, which help maintain the cell osmolarity and tissue water content.…”

We investigated the effects of exogenous application of jasmonic acid (JA) and nitric oxide (NO) on growth, antioxidant metabolism, physio-biochemical attributes and metabolite accumulation, in tomato (Solanum lycopersicum L.) plants exposed to salt stress. Treating the plants with NaCl (200 mM) resulted in considerable growth inhibition in terms of biomass, relative water content, and chlorophyll content, all of which were significantly improved upon application of JA and NO under both normal and NaCl-stress treatments. Salt treatment particularly 200 mM NaCl caused an apparent increase in electrolyte leakage, lipid peroxidation, and hydrogen peroxide production, which were reduced by exogenous application of JA and NO. Salt treatment triggered the induction of antioxidant system by enhancing the activities of antioxidant enzymes like superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR). Application of JA and NO separately as well as in combination caused a significant improvement in activities of SOD, CAT, APX, and GR activities. JA and NO either applied individually or in combination boosted the flavonoid, proline and glycine betaine synthesis under NaCl treatments. In conclusion, the exogenous application of JA and NO protected tomato plants from NaCl-induced damage by up-regulating the antioxidant metabolism, osmolyte synthesis, and metabolite accumulation.

“…Most studies on the response of plants to alkaline stress have been performed on plants grown in nutrient solutions (Yang et al ., , ; Li et al ., ; Zhang and Mu, ; Guo et al ., ; Cao et al ., ; Javid et al ., ; Gong et al ., ; Babuin et al ., ; Hu et al ., ) and, exceptionally, in soil (Ahmad et al ., ). However, nutrient solutions do not reproduce all the limitations of alkaline soils; studies performed in hydroponics, with plants supplied with high nutrient concentrations, have only addressed the high pH feature of alkaline soils.…”

Alkaline and saline–alkaline soils impose severe restrictions on plant growth. Panicum coloratum var. coloratum is a perennial C4 forage grass widely used in tropical and subtropical environments. Published information on its responses to alkaline soil conditions is scarce. The objectives of this study were (i) to characterize the effects of alkaline substrates on germination and initial growth in this species, (ii) to assess the influence of high pH in combination with reduced availability of either nutrients or oxygen and salinity, on plant growth and (iii) to evaluate some physiological traits potentially responsible for growth restrictions under alkaline soil conditions. Trials were conducted in a greenhouse. Germination and early plant survival were not affected by alkalinity. To isolate the effects of high pH, reduced nutrient and oxygen availability on growth, plants were grown either in neutral or alkaline soil, in hydroponics, in neutralized alkaline soil (with or without supplementary fertilization), or were flooded to induce hypoxia. Alkalinity effects on growth in hydroponics were milder than in soil. Growth in alkaline soil with nutrient supplement was still significantly lower (by 40%) than in neutral soil. Both alkalinity and hypoxia reduced growth non‐synergistically. These results show that studies of plant response to alkaline substrates carried out in aerated nutrient solutions can only partially address the complexity of this stress. Photosynthesis and PSII activity were among the physiological mechanisms negatively affected by alkalinity and may be partially responsible for the growth limitations observed in P. coloratum under alkaline conditions.

“…However, it is clear that these results cannot be exclusively used to understand the effects of two or more combined stresses on plants (Mittler , Suzuki et al ), because in field conditions, plants are exposed to more than one abiotic stress factor at the same time (Zandalinas et al ). Considerable progress has been made recently to elucidate the physiological, metabolic and molecular responses of the plants when different abiotic stress conditions are applied together to a wide variety of plant species (Rizhsky et al , Barnabas et al , Cvikrova et al , Ahmad et al , Perdomo et al , Zinta et al , Hu et al ).…”

“…Osmotic stress reduces the uptake of water and minerals such as K + and Ca 2+ (Glenn et al , Munns et al , Khan et al ). Ionic stress, caused by ions like Na or Cl accumulating in high amounts in the cytosol during saline conditions, damages the cell membrane and causes electrolytic leaching, which adversely affect metabolic activities in the cytosol such as photosynthesis, protein synthesis, lipid metabolism and nitrogen assimilation (Zhu , Chen et al , Ahmad , Pandolfi et al , Ahmad et al , Hashem et al ). Salinity stress also generates reactive oxygen species (ROS) that can readily damage cellular membranes through oxidation of lipids, proteins and nucleic acids (Foyer and Noctor ).…”

A study was carried out to assess the protective effects of exogenously applied nitric oxide (NO) in the form of its donor sodium nitroprusside (SNP) to strawberry seedlings (Fragaria × ananassa cv. Camarosa) grown under iron deficiency (ID), salinity stress or combination of both. The experimental design contained control, 0.1 mM FeSO (ID, Fe deficiency); 50 mM NaCl (S, Salinity) and ID + S. Plants were sprayed with 0.1 mM SNP or 0.1 mM sodium ferrocyanide, an analogue of SNP containing no NO. The deleterious effects of ID + S treatments on plant fresh and dry matters, total chlorophyll and chlorophyll fluorescence were more striking than those caused by the ID or S treatment alone. Furthermore, combination of salinity and iron stress exacerbated electrolyte leakage (EL) and the levels of malondialdehyde (MDA) and hydrogen peroxide (H O ) in plant leaves compared to those in plants grown with either of the single stresses. NO treatment effectively reduced EL, MDA and H O in plants grown under stress conditions applied singly or in combination. Salt stress alone and with ID reduced the superoxide dismutase (EC1.15.1.1) and catalase (EC 1.11.1.6) activities but increased that of POD (EC 1.17.1.7). Exogenously applied NO led to significant changes in antioxidant enzyme activities in either ID or S than those by ID+S. Overall, exogenously applied NO was more effective in mitigating the stress-induced adverse effects on the strawberry plants exposed to a single stress than those due to the combination of both stresses.
