Sažetak
Numerous studies so far confirmed the positive effects of low concentrations of hydrogensulfide (H2S) on the physiological response of plants, in the conditions of various types of abiotic stress. However, the effect of sodium hydrogensulfide (NaHS) as donor of H2S in plant organism is still not clarified enough. Here, the influence of NaHS solutions (0, 50, 100, 200 i 500 mM) applied into the supstrate, on the pepper plants (Capsicum annuum L.) grown in the presence of 150 mM NaCl was evaluated. On average, in both variants of NaCl stress, clorophyll content was unaffected by the applied NaHS treatments, whereas the highest NaHS concentration significantly reduced the carotenoid content. In salt stress conditions, the application of 50 as well as 100 mM NaHS significantly reduced lipid peroxidation rate in pepper leaves. Also, NaHS application lowered proline content regardless of salt stress. Leaf area of the plants treated with 50 and 100 mM NaHS was not significantly reduced in salt stress conditions. The obtained results suggest the positive effect of low H2S concentrations on pepper plants grown under salt stress conditions.
