Abstract:
The research's main goal was to evaluate the efficiency of exogenously administered GSH in order to improve the tolerance of canola grown under salinity stress in Brassica napus L. We performed experiments in two growth mediums viz. Petri plate and sand medium. The seeds of canola cultivars Shiralae were primed with distilled water and GSH (0.1mM) and grown under control and saline 75mL, 150mL, and 200mL) conditions. Plant photosynthesis, growth, germination, and water balance are all adversely affected by salinity. In response, plants also developed some defensive mechanisms like an antioxidant defense system. GSH is an antioxidant that reducessalinity stress. There are many antioxidants but we used glutathione to cope with the salinity stress. For this purpose, the seeds of Shiralee were primed with D.W and GSH was grown in control and stress conditions. The growth and biochemical parameters, were measured. By all counts and with proven results it is concluded that the exogenous application of GSH is very effective for enhancing the germination rate, germination percentage, growth, and dry and fresh weight under stress conditions. With increasing salinity levels, oxidative stress indicators such as H2O2 content increased in the leaves of canola plants. Our outcomes also revealed that exogenous GSH application can minimize oxidative stress and improve yield-contributing parameters. Therefore, we hypothesized that the exogenously applied GSH may reduce the adverse effects of salinity stress on canola.
