ABSTRACT

The effects of nickel on changes of roots physiological indices of zucchini cv. ‘Soraya’ and maize cv. ‘Złota Karłowa’ grown in the medium with various Ca contents were investigated using pot experiment. An attempt was made to explain this problem based on the following parameters: root volume, root adsorptive surface (total and active) and active surface of 1 cm³. Additionally, Ni and Ca contents were determined in roots. Three levels of nickel: 10, 40 or 60 mg Niˇkg^-1 (NiSO₄ˇ7H₂O) and two levels of calcium: 250 or 400 mg Caˇkg^-1 (CaCO₃) in the substrate were used in the study. Plants grown without nickel at lower and higher calcium level in the nutrient medium were used as control. It was found that the value of root physiological indices of the studied plant species grown in the medium containing 250 mg Caˇkg^-1 diminished with the increase of Ni the substrate. Increasing amount of nickel in the su

Key words: nickel, calcium, zucchini, maize, root physiological indicators.
