“…On the other hand, studying the effect of treatments on different levels of salinity showed that the application of treatments was effective in salinity resistance of seedlings, and consequently the activity of enzymes was decreased. Of course, there is also evidence that bacteria increased plant resistance to different stresses following the increased activity of antioxidant enzymes [63][64], which is inconsistent with the results of the present study. Probably the production of metabolites by growth-promoting bacteria, including growth-promoting hormones, plays a special role in stimulating and expressing antioxidant enzymes.…”

A greenhouse experiment was conducted to evaluate the effects regarding inoculation of exopolysaccharide (EPS)-producing bacterium, the extracted EPS and silicon nanoparticles on Solanum lycopersicum L. seeds under salinity stress, in a completely randomized factorial design with three replicates. The inoculated seeds with silicon nanoparticles (8 gr L -1 ), bacterial EPS (0.01 M), and 1 mL of bacterial suspension (1×10 8 CFU mL -1 ) were sown in pots and irrigated with water at different salinity levels (0.3, 2, 4, 6, and 8 dS m -1 ). Results showed that treatment application could enhance salinity tolerance of tomato seeds and improve plant growth so that combined treatments of EPS and silicon nanoparticles (S.E.N), bacteria and silicon nanoparticles (S.B.N), and EPS with silicon nanoparticles and bacteria (S.E.B.N) were the best treatments for plant growth and improvement regarding salinity levels. The mentioned treatments significantly (p<0.01) increased root and shoot fresh or dry weight in comparison to the control sample. In addition, treatments significantly (p<0.01) decreased proline content and antioxidant enzyme activities. Thus, it can be concluded that applied treatments are suitable for agricultural and environmental applications and bring about less damage caused by salinity stress.

“…Wheat Improvement, Management and UtilizationTuran et al conducted greenhouse experiments in wheat and barley under cold stress conditions to determine the growth, freezing injury, antioxidant enzyme activity effect of four different rhizobacteria and boron [149]. The authors showed that boron+PGPR treatments have positive effect on root and shoot growth, H 2 O 2 , and SOD, POD and CAT antioxidant enzyme activities of wheat and barley plants under cold and control conditions.…”

Free-living plant growth-promoting rhizobacteria (PGPR) have favourable effect on plant growth, tolerance against stresses and are considered as a promising alternative to inorganic fertilizer for promoting plant growth, yield and quality. PGPR colonize at the plant root, increase germination rates, promote root growth, yield, leaf area, chlorophyll content, nitrogen content, protein content, tolerance to drought, shoot and root weight, and delayed leaf senescence. Several important bacterial characteristics, such as biological nitrogen fixation, solubilization of inorganic phosphate and mineralization of organic phosphate, nutrient uptake, 1-aminocydopropane-1-carboxylic acid (ACC) deaminase activity and production of siderophores and phytohormones, can be assessed as plant growth promotion traits. By efficient use, PGPR is expected to contribute to agronomic efficiency, chiefly by decreasing costs and environmental pollution, by eliminating harmful chemicals. This review discusses various bacteria acting as PGPR, their genetic diversity, screening strategies, working principles, applications for wheat and future aspects in terms of efficiency, mechanisms and the desirable properties. The elucidation of the diverse mechanisms will enable microorganisms developing agriculture further.

“…Water transferred to root compartment through hyphae under drought conditions was only of 4% while, higher hyphal density found in the root compartment compared to hyphal compartment suggested that greater amount of water uptake may occurs in former one (Khalvati et al, 2005). Application of boron (6 kg ha -1 ) along with PGPR species namely Bacillus Megaterium, Bacillus subtilis, Azospirillum brasilense and Raoultella terrigena improved activity of antioxidant enzyme and significantly ameliorate oxidative stress due to freezing (Turan et al, 2013).…”

“…Under stress scenario, plant growth may be improved by using microbial based inoculation i.e., plant growth promoting rhizobacteria (PGPR) includes generally bacterial strains that have potential to synthesize growth promoting substances for plants viz., enzymes, phytohormones, siderophores, vitamins along with ethylene synthesis inhibitors, organic phosphate mineralizer, atmospheric nitrogen fixer and also resilience to various stresses (drought, metal toxicity and salinity etc.) (Vessey, 2003;Esitken et al, 2006;Turan et al, 2013). The mechanism of growth improvement by these microbes regulating hormonal and nutritional balance in plants, amplified production of plant growth regulators, enhance solubilization of nutrient for the ease in their uptake, hydration and impart resistance against pathogens (Boostani et al, 2014; Qurashi and Sabri, 2012).…”

Globally, abiotic stresses are major limiting factor in achieving optimum production and productivity of various crops. These stresses cause about 50% reduction in yields of various crops. Although, barley (Hordeum vulgare L.) is a comparatively abiotic stress tolerant crop but still abiotic stresses (drought, salinity, sodicity, acidity, water logging, heat, nutrient toxicities/ deficiencies etc.) affect the barley production and productivity. The duration of the stress and the plant's growth stage at which stress occurs affects the yield. For the sustainable barley production there is need that various abiotic stresses be effectively addressed through adoption of management practices like tillage and planting options, residue management, sowing time, stress tolerant cultivars, irrigation scheduling and integrated nutrient management. Barley potential to cope up against abiotic stress can be further accelerated by synchronizing breeding and agronomic, climatic driven and location specific researches.
