How autochthonous microorganisms influence physiological status of Zea mays L. cultivated on heavy metal contaminated soils?

ABSTRACT: The aim of this study was to investigate the effect of autochthonous microorganisms present in soil collected from heavy metal (HM) uncontaminated (Pb ≈ 59 mg kg^-1, Cd ≈ 0.4 mg kg^-1, Zn ≈ 191 mg kg^-1), moderately (Pb ≈ 343 mg kg^-1, Cd ≈ 12 mg kg^-1, Zn ≈ 1876 mg kg^-1), and highly (Pb ≈ 1586 mg kg^-1, Cd ≈ 57 mg kg^-1, Zn ≈ 3280 mg kg^-1) contaminated sites on Zea mays elemental composition, physiological status, and growth parameters. For this purpose, half of the collected soil was sterilized and soil characterization was performed. After 45 days of cultivation, the presence of HM in the soil negatively affected photosynthesis and transpiration rates, relative chlorophyll content, anthocyanins i
