Abstract
In order to evaluate the phytotoxicity of the anionic surfactant sodium dodecyl sulfate (SDS), the inhibition of wheat seed germination was investigated. The effects of SDS on antioxidant enzyme activities [catalase and gluthione reductase (GR)], protein, soluble sugar, and proline in wheat (Triticum aestivum L.) seedlings were investigated after 6 days of SDS stress. With the increase in the SDS concentration, the root length of the wheat seedlings were inhibited markedly, and the protein content of the shoot decreased gradually. SDS stress caused significant changes in GR activity, soluble sugar, and proline contents in the shoots and roots of wheat. Accumulations of proline were observed in the shoots and roots and SDS caused growth inhibition on the wheat seedling. © 2015 American Institute of Chemical Engineers Environ Prog, 34: 1142–1147, 2015
