Triton-X-405, Brij 35 ve Brij 76 Surfaktanlarının Lens culinaris Medik. (Mercimek) Tohumlarının Gelişimi Üzerindeki Etkilerinin Gözlenmesi

Abstract

In this study, different kinds of solutions of three nonionic surfactants named as polyoxyethylene (23) lauryl ether (C12E23) (Brij 35) and polyoxyethylene (10) stearyl ether (C18E10) (Brij 76) and an octylphenol (OP)-type surfactant, [4-(1,1,3,3-tetramethylbutyl)phenyl]-whydroxily-(oxy-l, 2-ethanediyl) (Triton X-405) were selected to examine their phytotoxic effects. They were evaluated under laboratory conditions using lentil (Lens culinaris Medik. cv. Sultan) as a test material. Surfactants used in this study were tested at the concentration ranges of 1.00, 0.50, 0.25, and 0.12 g/L (w/v). The phytotoxic effects were examined on germination rates after 2th days and on root elongation after 7th days. EC50 determined only at 1 g / L concentration of Brij-76. Phytotoxic and stimulator effects has been observed on root growth and on seed germination with the other three concentrations. Phytotoxic effects increase according to the control group as concentration increases, the stimulatory effects increase according to the control group as concentration decreases.
