TL;DR: The key mechanisms of Si-mediated alleviation of abiotic stresses in higher plants include: stimulation of antioxidant systems in plants, complexation or co-precipitation of toxic metal ions with Si, immobilization of toxicMetal ions in growth media, uptake processes, and compartmentation of metal ions within plants.

TL;DR: Exogenous Si significantly enhanced these enzyme activities in roots of salt-stressed plants compared to Si-deprived salt treatments, and the effects of Si-enhanced salt tolerance are discussed with respect to cell membrane integrity, stability and function in barley.

TL;DR: In this paper, two contrasting barley (Hordeum vulgare L) cultivars: Kepin No7 (salt sensitive) and Jian 4 (Salt tolerant) were grown in a hydroponics system containing 120 mol m-3 NaCl only and 120 mol n 3 Si (as potassium silicate) compared with the plants treated with salt alone, superoxide dismutase (SOD) activity in leaves and H+-ATPase activity in plant roots increased, and malondialdehyde (MDA) concentration in plant leaves decreased

TL;DR: The results suggest that Si-enhanced tolerance to Cd can be attributed not only toCd immobilization caused by silicate-induced pH rise in the soils but also to Si-mediated detoxification of Cd in the plants.

TL;DR: The use of slag-based silicate fertilizers in agriculture can be traced back to the Middle Ages in Europe as discussed by the authors and has been well documented to play an important role in providing benefits on growth and yield, especially in plants under stressful environments.
