摘要

研究了低剂量和极低剂量生物活性物质germatranol对高胁迫条件下小麦根系呼吸速率和活性氧含量的影响。结果表明,10-5 ~ 10-10 M(根据温度不同)浓度的物质溶液可提高小麦胚芽的耐热性,并影响活性氧含量和呼吸速率。据推测,germatranol对植物的生长发育有积极的影响,并在植物细胞中起到抗氧化剂的作用。

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

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.
