Role of Cystoseira mediterranea extracts (Sauv.) in the Alleviation of salt stress adverse effect and enhancement of some Hordeum vulgare L. (barley) growth parameters

Abstract

Cystoseira mediterranea (Sauv.) extract was tested for its ability to restore barley (Hordeum vulgare) growth under salt stress (350 mM NaCl), shoot growth; membrane integrity; lipid peroxidation and hydrogen peroxide determination were performed. In normal conditions, the obtained data revealed the ability of the extract to stimulate most of barley growth parameters. However, it showed significant effect on most of barley growth parameters (plant height, fresh and dry weight of shoots and roots) and chlorophyll content, under salt stress. The measurement of stress parameters (membrane integrity, lipid peroxidation and hydrogen peroxide) revealed significant effect of C. mediterranea extract on reducing the deleterious impact of salt stress on barley seedlings.
