This research aimed to ameliorate the negative effects of water deficit stress using silicon application on strawberry. The experiment was conducted as a factorial in a completely randomized design with three factors including cultivar (‘Selva’ and ‘Gavioita’), Na2SiO3 (Sodium silicate) concentrations [0, 3, and 6 mM), as the source of silicon, and water deficit stress (40%, 60%, 80%, and 100% of field capacity (FC)], in three replications. ‘Gavioita’ cultivar showed the highest superoxide dismutase enzyme activity in leaves under sever water deficit stress (40% of FC) following Na2SiO3 (3 and 6 mM concentrations) application. Application of Na2SiO3 at concentration of 6 mM increased the catalase enzyme activity significantly in the leaves of ‘Gavioita’cultivar under severe water deficit stress (40% of FC). The activity of peroxidase enzyme was enhanced considerably under 80% of FC and lower water deficit in the fruits of both cultivars. The fruit total anthocyanin level was increased significantly by application of Na2SiO3 at 3 and 6 mM concentrations under water deficit stress (60% of FC). Also, Na2SiO3 (at concentrations of 3 and 6 mM) enhanced the proline level significantly in ‘Gavioita’ cultivar compared to the control treatment under normal conditions (100% of FC). In conclusion, the results of present study indicated that application of Na2SiO3 at 6 mM concentration is useful treatment to cope with sever water deficit stress (40% of FC) especially in ‘Gavioita’ cultivar of strawbery UR - https://ijhst.ut.ac.ir/article_84988.html L1 - https://ijhst.ut.ac.ir/article_84988_06abcaeef0707d7641be4739e80f96c0.pdf ER -
