IMPACT OF CADMIUM TOXICITY ON LEAF AREA AND STOMATAL CHARACTERISTICS IN FABA BEAN

Although changes in stomatal response to elevated doses of cadmium has already been observed several plants, few studies have focused on this phenomenon more detail. The effects different Cd2+ (50 and 100 mg.kg-1 soil) leaf area characteristics (number stomata, number epidermal cells, index size stomata) faba bean (Vicia L. cultivar Aštar) were studied after 15 days heavy metal treatment. No visual adaxial or abaxial side leaves the tested variety found. was higher by 14.15 % at lower 12.23 Cd. Cd did not lead a change stomata. cells increased 4.98 dose Cd50. Stomatal decreased due effect 11.38 leaves. In widths, decrease 2.04 (adaxial side) 2.26 (abaxial length 1.85 3.89 (Cd50) 4.63 (Cd100) respectively. variations could be signals tolerance adaptive mechanisms under used concentrations cadmium.
