Abstract. Among abiotic stresses, water deficiency is one of the most destructive environmental stresses. When a plant encounters water stress, it releases some antioxidants (enzymes) to alleviate water stress. Peroxidases are considered one of the indicators of plant stress, since their level significantly increases after stress stimulation. Among the studied six varieties and four lines of mung bean (Vigna radiata L.), the Zilola variety showed high activity of the peroxidase enzyme under conditions of water deficit. This, in turn, proves the resistance of the Zilola variety to water deficiency in comparison with other studied mung bean varieties.
