Annotation	The accumulation of toxic metals (Cd, Co, Cu and Ni) by Allium sativum plants was followed under hydroponic conditions. The toxic metals were applied at two concentrations (0.05 and 0.25 mM). The effects of heavy metals on chlorophyll and carotenoid content, root length and amino acid exudation were examined to evaluate the impact of heavy metal accumulation on plant growth and development. A significant hyperaccumulation of cadmium by garlic roots was observed. Cobalt stimulated carotenoid production in garlic leaves. Copper accumulation was associated with increased exudation of amino acids to the cultivation medium and elevation of chlorophyll content in leaves. Nickel significantly reduced root growth.
