The Effect of Nickel and Iron on Soil acidity and Growth Parameters in Stipacapensis (Case study: Gachsaran oil-rich region)

Selection of resistant species with an ability to make adaptation with the local contaminated site is a key factor in the success of phytoremediation. The aim of this study was to evaluate the effect of different concentrations of Fe, Ni on seed emergence and plant height of Stipacapensis under laboratory conditions.
A factorial experiment based on completely randomized design with three replications was used. Pollutant substances (iron and nickel) and pollutant concentrations (0, 100, 150, 200ppm) were considered as the first and second factors, respectively.
Findings: The results showed that the effect of different amounts of iron and nickel on seed emergence and plant height of Stipacapensis was significant (p Overall results indicate the negative effects of Fe, Ni on seed germination as well as plant height of Stipacapensis.However, germination of Stipacapensis at the highest concentration of elements, indicate the relatively tolerance of this species to soil contamination elements in this study.
