The aim of this study was to evaluate the effects of mycorrhizal inoculation and phosphorus (P) application on arsenic (As) toxicity and absorption by fenugreek, after application of As to soil. In this greenhouse experiment, plants inoculated with three mycorrhizal species and grown in soils with different levels of applied P and As, were compared. Phytotoxicity of As was determined by study...

Cadmium (Cd) is easily absorbed by the root system in many plant species and due to its solubility in water and toxicity is considered as a major pollutant. The aim of this study was investigation of cadmium toxicity on some physiological characteristics of lentil seedlings. So, two-week-old plantlets were treated with different concentrations (0 as control, 0.125, 0.25, 0.5, 1, 2.5 and 5 μM...

Zinc is one of micronutrients which reduces toxicity of sodium in plants and plays an important role in helping to the survival of crop plant under salinity stress. The research was conducted in a factorial experiment in completely randomized design with three replications in arak university in 1391 autumn. In this study, the effects of four salinity levels (0, 45, 90 and 120 mM NaCl) and three...

In order to evaluate the effect of Piriformospora indica fungi inoculation on antioxidant systems and photosynthetic pigments of stevia medicinal plant under salt and drought stresses, an in vitro experiment was conducted. Experiment arranged in factorial based on completely randomized design with three replicates. Treatments were three levels of osmotic potential (0, -5, and -10 bar), three os...
