[Physiological effects of taurine on the growth of wheat (Triticum aestivum L.) seedlings].
Wheat (Triticum aestivum L.) seedlings were grown in taurine solution at concentrations of 10, 100, 500, 1000 and 5000 mg/L, and the photochemistry efficiency, the relative permeability of membrane, membrane lipid peroxidation and the growth indexes in wheat seedlings were determined. The results showed that taurine treatments distinctly promoted the growth of wheat seedlings and increased root length, plant height, dry weight and fresh weight single plant of wheat seedlings. In addition, the photochemistry efficiency in the leaf was also increase, and the membrane relative permeability and the content of membrane lipid peroxidation product MDA were decreased, with an optimum treatment concentration at about 500 mg/L. It suggests that taurine has protective effects on the cell membrane of wheat seedlings to the certain extent.
