Abstract

The Poaceae family is consists of plants popularly known as grasses and has a high number of species adapted to different habitats. In view of this, the present work aimed to analyze the influence of saline and water stresses in total amino acids content of Pennisetum glaucum plants. For saline stress, the plants were subjected at treatment with 60 mM of NaCl, while that for water stress was used 8% of polyethylene glycol in the nutritive solutions. The experimental design was a completely randomized design with three treatments (water stress, saline and control) and seven replications. The content of amino acids as response to hydric deficiency and at salinity had higher registration in the new leaves, where only the salinity influenced the content of amino acids. In general, the amino acid content in new leaves, intermediates and roots were not influenced by the stresses studied. Thus, the species showed to be well adapted at water and saline stress conditions, increasing the amino acid content in their tissues.
