ABSTRACT

Abiotic stress factors negatively influence crop production all over the world. The human population is globally increasing every year. Therefore, to ensure sufficient food and feed, plants need to be grown on sites where they are exposed to negative abiotic stresses like heavy metals and other toxic elements, drought, and increased salinity. The mechanisms that help plants to overcome these stresses are intensively studied. Silicon (Si) was shown to be a promising agent to alleviate various forms of biotic as well as abiotic stresses on plants. Therefore, the prospective use of Si in agriculture is gaining attention. This chapter reveals how Si mitigates the negative effects of selected abiotic stresses on plants.
