EnglishThe effect of Ca2+, Mg3+ and Ni2+ on root elongation was studied in Alyssum bertolonii Desv., a nickel-accumulating and serpentine endemic species. The results confirm the detoxifying action of Ca2+ which reduces the toxic effect of Mg2+ and Ni2+ on root development. In addition, Ca2+ and Mg2+ interact positively in depressing Ni2+ uptake. The combined effect of these two ions is of relevance for the mechanism of nickel tolerance in A. bertolonii.
