| dc.description.abstract | This study investigated the effect of foliar-spray of exogenous proline on cadmium-stressed tomato seedlings for two successive seasons at the experimental farm of Adeleke University, Ede, Nigeria. The seedlings were grown in a nursery bed for 4 weeks and thereafter transplanted. Two weeks after transplantation, the plants were stressed with cadmium and the foliar part was sprayed with proline the same day they were subjected to cadmium stress as follow in triplicate: treatment 1: control; treatment 2: 0.3 mM cadmium (Cd); treatment 3: 1.2 mM Cd; treatment 4: 0.3 mM Cd + 5 mg/l proline; treatment 5: 0.3 mM Cd + 10 mg/l proline; treatment 6: 0.3 mM Cd + 15 mg/l proline; treatment 7: 1.2 mM Cd + 5 mg/l proline; treatment 8: 1.2 mM Cd + 10 mg/l proline and treatment 9: 1.2 mM Cd + 15 mg/l proline. The experiment was laid in a complete randomized design with three replications. The farm plots were irrigated on a 2-day basis. The parameters studied were lipid peroxidation, enzymatic activities, fruit yield, and proximate composition of the fruit. The result showed that Cd stress caused increase in lipid peroxidation and reduced tomato fruit yield. Application of proline to the stressed plants lowered the lipid peroxidation level, raised enzymatic activities, and increased fruit yield, and total protein content. Plots stressed with 0.3 mM Cd and sprayed with 15 mg/l proline gave fruit yield which was significantly the same with the yield of control. The study concluded that application of proline mitigated the harmful effects of cadmium stress on S. lycopersicum and hence, can be integrated into farming in cadmium-polluted area. | |
