Abstract

The effect of heat drying and NaF on the viability and soluble proteins of wheat seeds was analyzed. Protein content measurements and sodium dodecyl sulfate polyacrylamide gel electrophoresis were carried out on germ (plantlet) and endosperm during the first four days of germination. Results showed that the viability of both normal and heated seeds decreased exponentially with NaF concentration. The parameter most affected by both NaF and heating was plantlet size. Although some differences in the electrophoretic patterns corresponding to different treatments were found, results showed similar trends in most of them, and the main changes appeared between different days of germination. Additive effects of both NaF and heating were observed in some cases.
