Abstract

To assess modulation in growth, oxidative defense mechanism and mineral nutrients of canola by foliar-applied triacontanol (TRIA) under salt stress, a greenhouse experiment was performed on canola cultivar RBN-3060. Plants were grown in full strength Hoagland’s nutrient solution for 56 days under non-saline condition, after which time, they were subjected to saline conditions (0 (control), 100 and 150 mM NaCl). Three levels of TRIA (0, 0.5 and 1 mg L-1) were applied as foliar spray. Root-growing medium salt stress significantly decreased shoot and root dry weight, seed yield and activity of POD, shoot and root K+ and Ca2+ while increased the activity of SOD and catalase, accumulation of proline and GB and shoot and root Na+ and Cl-. Foliar-applied TRIA enhanced growth and yield under non-saline conditions, accumulation of proline and GB and oxidative defense system under both saline and non-saline condition. Overall, TRIA application was effective in alleviation of salt induced adverse effects on canola by increasing accumulation of proline, GB, K+ and Ca2+.
