Abstract:

Salinity Stress is one of the most important abiotic stresses that cause adverse effects on crop productivity and agricultural sustainability. The present experiment was carried out as a pot-culture in the poly-house on pea genotype HUP-2 under salinity stress, and identified various biochemical attributes which were progressively reduced with increase in salinity level due to formation of reactive oxygen species i.e. hydrogen peroxide (H2O2) and superoxide radical (O2.-). Treatment of seeds with Trichoderma asperellum (T42) and exogenous application of salicylic acid, solitary or in combination, ameliorated salt stress induced responses as reflected by detoxification of both reactive oxygen species, H2O2 and O2.- and also observed reduction in lipid peroxidation by enhancement of osmoprotectants i.e. proline content and activation of antioxidative enzymes activity like superoxide dismutase and ascorbate peroxidase as compared to control of respective salinity levels (4, 8 and 12 dSm-1). Exogenous foliar application of SA (0.25 mM), singly and in combination of Trichoderma, ameliorated the hostile effects of salinity up to the level of 8 dSm-1 which showed a significant expansion of plant phenotype as compared to the untreated stressed plants.
