Soil and water salinity in semi-arid regions such as Iran have been a important threat for plant growth and agriculture. It is demonstrated that TiO2 nanoparticles can improve plant growth and increase stress tolerance in plants. Therefore, in current study, a pot experiment was conducted as factorial with completely randomized design to evaluate the effect of 3 levels of salinity (0, 50, ...

The soil salinity and the diffusion of potentially toxic chemicals to the soil environment through industrial and agricultural activities are known as important factors affecting the productivity of crop plants. Thus, an efficient strategy to increase crop yield, and to improve human and environmental health, is necessary to mitigate the impacts of these detrimental factors. Accordingly, a fact...

The current experiment was designed to evaluate the effect of plant growth promoting rhizobactria (PGPR) on chlorophyll fluorescence and some physiological parameters in basil (Ocimum basilicum L.) leaf under salinity stress. The experiment was conducted in factorial arrangement based on completely randomized design. Treatments were four levels of salt stress (0, 40, 80 and 120 mM of NaCl) and ...

In order to investigate the effect of putrescin and salicylic acid on some physiological and antioxidant properties of stevia under salinity stress, a factorial experiment was conducted in a completely randomized design with three replications. In this experiment, samples were exposed to different concentrations of putrescine (0, 0.5 and 1 mM), salicylic acid (0 and 0.5 mM) and salinity (0, 75 ...

In order to evaluate the effect of plant growth-promoting rhizobacteria) PGPR( on salt tolerance in vegetative and reproductive growth stages of safflower (Carthamus tinctorius), a randomized complete block design with a factorial combination of bacterial inoculation and salinity, each in three levels, and four replications was conducted in experimental glasshouse of Vali-e-Asr University of Ra...

The effects of salinity and complementary silicon on some morphological traits of canola, cv. Talaiie, an experiment was done in greenhouse. Treatments were four levels of potassium silicate (0, 1, 2 and 3mM) and four levels of chloride sodium (0, 0.3, 0.6 and 0.9 g/kg soil). In normal condition application of silicon had not a significant effect on measured traits. Salinity decreased leaf area...
