Sažetak
Aluminium (AP+) toxicity can cause inhibition of plant root growth and disturbance of its activity. A13+ can cause displacement of cations such as calcium (Ca2+) and magnesium (Mg2+) from the apoplast of root cells and in addition can inhibit their uptake. The aim of this experiment was to investigate the effect of toxic levels ofAl3+ on uptake and translocation ofCa2+ and Mg2+ of potato plants. Eleven potato cultivars were vegetatively grown on nutrient solutions pH 4, 0 with three different levels of toxic aluminium (0, 25, 0, 5 and 1, 0 mMAl3+ L-l), and control (without AI3+). After six days of growth, plants were divided on roots and shoots, and the concentrations of Al 3+, Ca2+ and Mg2+ of potato roots and shoots were determined. Significant differences in concentrations of AI3+, Ca2+ and Mg2+ in both roots and shoots were found among potato cultivars grown on nutrient solutions with different levels of AI3+. The significantly highest concentrations of A13+ in roots and shoots were determined in plants grown on nutrient solution with 1, 0 mMAI3+ L-1, 27 213 mg kg-l of dry weight (DW) and 200, 36 mg kg-l DW, respectively. Concentrations ofCa2+ and Mg2+ in roots and shoots significantly decrease with increasing A13-! concentrations in nutrient solutions, with lowest concentrations in plants grown on solution with 1, 0 mMAI3+L-1, 0, 75 % and 1, 58 % ofCa2+ and 0, 55 % and 0, 46 % ofMg2+ in roots and shoots, respectively.
