Abstract
Under diverse salt stress circumstances, the effects of exogenous silicon are examined (1 mM Na-silicate, Si) on wheat relative water content (RWC), chlorophyll (chl) content, yield, and antioxidant defense mechanisms under salt stress.The experiment included two varieties of wheat, BARI Gom 21 and BARI Gom 25, as well as the following treatments: control, control+Si, S50 (50 mM NaCl), S50+Si, S100 (100 mM NaCl), S100+Si, S150 (150 mM NaCl), S150+Si, S200 (200 mM NaCl), and S200+Si.Salt stress significantly decreased the RWC and chl, malondialdehyde (MDA) and H2O2 levels increased in response to the salt stress.Reduced levels of ascorbate (AsA) and glutathione (GSH) were the result of salt stresses.However, as salinity levels grew, glutathione disulfide (GSSG) concentrations surged as well.Ascorbate peroxidase (APX), monodehydroascorbate reductase (MDHAR), dehydroascorbate reductase (DHAR), and catalase (CAT) activities all dramatically decreased in response to salt stress, but catalase (CAT) activity only increased at 100 mM NaCl.Glutathione S-transferase (GST) and glutathione reductase (GR) activity significantly increased during severe salt stress (200 mM).However, when salinity increased, peroxidase (POD) activity decreased.Salt stress at harvest reduced the yield of grains and straw for both wheat varieties.Exogenous Si therapy on salinity stress improved physiological characteristics, decreased oxidative damage, and increased yield of both cultivars where BARI Gom 25 showed higher resistance.Si therapy, however, was unable to boost physiological traits, or yield at exceptionally high levels of salt stress.
