[Impossible mechanisms of germatranol influence on the thermal stability of wheat germs].

Abstract

The influence of biologically active substance germatranol in low and very low doses on the respiration rate and the content of reactive oxygen species (ROS) in wheat roots under conditions of high stress was investigated. The results showed that solutions of the studied substance in concentrations of from 10–5 M to 10–10 M (depending on the temperature) increase the thermotolerance of wheat germs and affect the ROS content and respiration rate. It is assumed that germatranol can have a positive impact on plant growth and development and act as antioxidants in plant cells.
