“…Numerous adverse effects of salinity, such as ion toxicity, osmotic stress, generating a surplus of reactive oxygen species (ROS) and nutrient deprivation are detrimental to plant growth (Acosta-Motos et al, 2017). Oxidative stress caused by an excess of ROS controlled by the cellular defense system, such as enzyme antioxidants including ascorbate peroxidase, catalase, and superoxide dismutase and non-enzymatic antioxidants (Bidabadi et al, 2021). In order to control a variety of cell processes throughout growth and development of plants, ROS must be at an optimal level because macromolecules such as membrane lipids are damaged by excessive ROS generation .…”

The purpose of this research was to nd out how in vitro culture of tomato explants respond to salt stress by silver nitrate (AgNO 3 ) and pyrazinamide (PZA) as ethylene inhibitors. Tomato seedlings were grown on MS medium containing NaCl (0, 100, 150 mM) and supplemented with AgNO 3 (0, 2, 4, mg. L -1 ) and pyrazinamide (PZA) (0, 2, 4,mg. L -1 ) to study growth parameters and antioxidant enzymes responses. Salt-stressed plants showed limited growth and a signi cant decrease in fresh and dry weight. Salinity accelerated oxidative damage by increasing hydrogen peroxide (H 2 O 2 ) and malondialdehyde (MDA) levels in tomato leaves. In the present of AgNO 3 and PZA, in vitro grown tomato plants increased fresh and dry weight total chlorophyll, carotenoid in particular at 4 mg. L -1 AgNO 3 and 4 mg. L -1 PZA. Moreover, silver nitrate and PZA reduced H 2 O 2 and MDA contents and oxidative damage by enhancing antioxidant enzyme activity, including catalase, superoxide dismutase, and ascorbate peroxidase under salt stress. According to our ndings, AgNO 3 and PZA improved in vitro salinity tolerance of tomato plant by interfering ethylene action or ethylene generation and increasing biochemical responses.
