چکیده
Amendment of saline soils with biochar and rhizobacteria is a new technique to diminish the negative impacts salt stress on plants. Hence, an original pot experiment was conducted in glass greenhouse at University Tabriz investigate performance salt-stressed (0, 6 12 dS m?1 NaCl) rapeseed (Brassica napus L.) plants response different biochar-related treatments (non-biochar, biochar, biochar-based Pseudomonas putida RS-198, Azotobacter chroococcum RS-106 both bacteria). The reduced sodium content, generation reactive oxygen species, lipid peroxidation enzymatic antioxidants plant tissues while enhanced nutrient non-enzymatic antioxidants, main lateral roots lengths weights, main/lateral root length ratio, specific length, diameter, shoot weight, leaf area, chlorophyll content seed oil yields under conditions. + superior treatment for reducing harmful plants, which resulted 83–109% 69–115% improvements this crop moderate high salinities, respectively. Therefore, inoculation might be novel approach improving tolerance productivity

Field experiments were conducted using a randomized complete block design with five PGPRs (Bacillus subtilis EY2, Bacillus atrophaeus EY6, Bacillus spharicus GC subgroup B ...
متن کاملPlant Growth Promoting Rhizobacteria in Amelioration of Salinity Stress: A Systems Biology Perspective
Salinity affects plant growth and is a major abiotic stress that limits crop productivity. It is well-understood that environmental adaptations and genetic traits regulate salinity tolerance in plants, but imparting the knowledge gained towards crop improvement remain arduous. Harnessing the potential of beneficial microorganisms present in the rhizosphere is an alternative strategy for improvi...
