Abstract: (16 Views)
To evaluate the response of the antioxidant defense system of three sugar beet genotypes to drought stress, a two-year field experiment was conducted at the Research Site of the Sugar Beet Seed Institute of Karaj, Iran (2018-2019). The irrigation treatments were arranged in the main plots during growing seasons and included 80 mm (control (I1)), 130 mm (I2), and 180 mm (I3), evaporation from an A-class pan under surface irrigation method, 30 mm (I4), 80 mm (I5), 130 mm (I6), and 180 mm (I7: as severe drought); evaporation with 100% volume of water requirement under trickle irrigation (tape) method; and 30 mm (I8) evaporation with 75% volume of water requirement under trickle irrigation (tape) method. The second factor was genotype types included: 7112 (G1), BP-Karaj (G2), and BP-Mashhad (G3) were in the subplots. The results showed that drought stress increased the activities of catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPX) in sugar beet leaves. There were significant differences among genotypes for antioxidant enzyme activity. Also, irrigation × genotype interactions showed a significant difference in CAT and GPX activities. In addition, drought stress caused the production of reactive oxygen species (ROS), which results in greater membrane permeability, malondialdehyde (MDA) content, and oxidative stress in the plants. Moreover, genotypes having greater levels of antioxidants showed better resistance to drought stress.
