Effect of Silicon on Oat Salinity Tolerance: Analysis of the Epigenetic and Physiological Response of Plants

Environmental conditions are the primary factor determining growth and yield of plants. As a result climate change, negative impact abiotic factors is intensifying. One them salt stress. Soil salinity one major problems in agriculture world affects many cultivar species. The aim this study was to evaluate effect silicon foliar application on physiological epigenetic reaction oats (Avena sativa L.) under pot experiment carried out controlled conditions. Oat plants were subject sodium chloride (NaCl) at concentration 200 mM applied soil. Three concentrations Optysil (200 g∙L−1 SiO2) used for fertilization. Measurements made relative chlorophyll content leaves, selected fluorescence parameters, gas exchange parameters. In study, methylation-sensitive amplification polymorphisms (MSAP) analysis investigate Si during stress DNA methylation level oat results indicated that exogenous improved tolerance salinity. doses 0.1% 0.2% had greatest alleviating research, as well response experimental analyzed, which broad coverage research topic effects
