Abstract

Silicon is an essential element in plant nutrition and plays an effective role in tolerance to biotic and abiotic stresses. The study aimed to investigate the effect of sodium silicate and silicate-solubilizing bacteria on the interaction between eggplant and dodder infestation. The pot study was conducted at Bu-Ali Sina University in 2022 as a three-factor factorial based on a completely randomized design with six replications. The first factor included the dodder infection of eggplant (with and without infection). The second factor included the application of sodium silicate (zero and 100 mg per kg of soil. The third factor included soil inoculation with silicate-solubilizing bacteria (zero and 10 ml per kg of soil). The results showed a synergistic effect when using combined sodium silicate and silicate-solubilizing bacteria. When the soil was treated with sodium silicate and silicate-solubilizing bacteria, the infection of eggplant with dodder caused a decrease in shoot dry weight (32%), root dry weight (41%), and silicon content (28%) and an increase in lignin content (53%), phenylalanine ammonia-lyase activity (27%), catalase activity (214%), peroxidase activity (202%), superoxide dismutase activity (194%), lipoxygenase activity (156%), H2O2 content (58%) and malondialdehyde content (94%). The co-application of sodium silicate and silicate-solubilizing bacteria synergistically reduced the dodder biomass. So the combined use of sodium silicate and silicate-solubilizing bacteria could compensate for the damage caused by this parasitic weed to eggplant biomass.
