Silicon improves seed germination and alleviates oxidative stress of bud seedlings in tomato under water deficit stress

Effects of silicon on absorbed light allocation, antioxidant enzymes and ultrastructure of chloroplasts in tomato leaves under simulated drought stress

“…In addition, some studies suggest that POD has a protective effect, but can also be involved in chlorophyll degradation, ROS generation, and membrane lipid peroxidation, which are a response to injury and a product of senescence (Yang and Gao, 2000). In our study, drought stress induced activation of POD in the chloroplasts of plants without Si, but Si application suppressed activation of POD in the chloroplasts, in agreement with Shi et al (2014). Therefore, Si can suppress the chlorophyll degradation caused by activation of POD in the chloroplasts.…”

Influence of Exopolysaccharide-Producing Bacteria and SiO2 Nanoparticles on Proline Content and Antioxidant Enzyme Activities of Tomato Seedlings (Solanum lycopersicum L.) under Salinity Stress

“…Concerning the effect of silicon on antioxidant enzymes activities, some of the evidence suggests that silicon reduces the biological and non-biological stresses in plants by enhancing the antioxidant defense system [65][66][67]. The present results showed that the activity of superoxide dismutase in tomato was enhanced by increasing the salinity level.…”

Effects of Silicon on Maize Photosynthesis and Grain Yield in Black Soils of China

“…Silicon (Si) is the second most abundant element both on the surface of the Earth's crust and in soils (Liang et al, 2007;Gottardi et al, 2012;Ali et al, 2013;Shi et al, 2014). Silicon has been proved to be beneficial for the healthy growth and development of many plant species, particularly graminaceous plants such as rice and sugarcane and some cyperaceous plants (Liang et al, 2007).…”
