The variations of response could be signals of tolerance or adaptive mechanisms of the leaves under the determined concentrations. Deeper anatomic and physiological studies can contribute to the explanation of the role of cell epidermis of faba bean in its adaptation to ions of cadmium. | IMPACT OF CADMIUM TOXICITY ON LEAF AREA AND STOMATAL CHARACTERISTICS IN FABA BEAN Beáta Piršelová 1 Veronika Kubová1 Peter Boleček1 Alžbeta Hegedűsová2 Address es 1 Constantine the Philosopher University in Nitra Faculty of Natural Sciences Department of Botany and Genetics Nábrežie mládeže 91 949 74 Nitra Slovakia. 2 Slovak University of Agriculture in Nitra Faculty of Horticulture and Landscape Engineering Department of Vegetable Production Tr.

Corresponding author bpirselova@ https ARTICLE INFO ABSTRACT Received 16. 9. 2020 Although changes in stomatal response to elevated doses of cadmium has already been observed in several plants few studies have Revised 30. 4. 2021 focused on this phenomenon in more detail. The effects of different doses of cadmium Cd2 50 and 100 soil on leaf area and Accepted 11. 5. 2021 stomatal characteristics number of stomata number of epidermal cells stomatal index and size of stomata of faba bean Vicia faba L. Published 1. 10. 2021 cultivar Aštar were studied after 15 days of heavy metal treatment. No visual changes on adaxial or abaxial side of leaves of the tested variety of faba bean were found. The leaf area was higher by at lower and by at the higher doses of Cd. The tested doses of Cd did not lead to a change in the number of stomata. The number of epidermal cells was increased on adaxial side by Regular article at dose Cd50. Stomatal index was decreased due to the effect of higher dose of cadmium by on adaxial side of leaves. In stomatal widths decrease by adaxial side and abaxial side was observed at higher doses of Cd. In stomatal length decrease by was observed at higher dose of Cd on adaxial and decrease by Cd50 and Cd100 on abaxial side of leaves respectively. The variations of response could be signals of tolerance or adaptive mechanisms of the leaves of tested bean cultivar under the used .
