Abstract
In the present study, the effects of silicon nutrition under salinity stress have been investigated on Arabidopsis thaliana plants grown on hydroponic culture. The experiments were conducted in a completely randomized design in factorial form. The first factor was salinity including 0, 50, 100 and 150 mM NaCl and the second factor was silicon including 0 and 1.5 mM sodium silicate. The results indicated that salinity increased concentration of Na+ and decreased relative water content and concentration of Ca2+, K+ and Mg2+ about 27, 49, 66 and 19 percent respectively. Consequently, plants were faced with oxidative stress that caused enhancement of antioxidant enzyme activities as well as phenols. In addition, salinity stress increased soluble sugars and decreased starch content that probably indicated plant acclimation for insufficient osmotic adjustment. Silicon nutrition alleviated the oxidative stress caused by salinity that may associated to the increasing K+ and Mg2+ content and raising antioxidant enzymes activity. Beside, increase of reducing sugars, decrease of starch and enhancement of relative water content following silicon application indicated improvement of plant water status. As a result, silicon fed plants indicated greater growth compared to non silicon fed ones under salinity. The results indicated that silicon could mitigate salinity stress in Arabidopsis thaliana plants through minimizing oxidative stress and improvement of water status.
