Overview

Assessment revealed serotonin increases biomass and chlorophyll in grapevines under selenium stress, suggesting a protective role.

Key Points

  • Serotonin treatment improved biomass by 6.83% in roots and 9.25% in shoots under selenium stress, fostering growth.
  • Higher chlorophyll a levels increased by 7.15%, while chlorophyll b remained unaffected in stressed grapevines.
  • Application of serotonin also elevated peroxidase activity, despite no changes in superoxide dismutase or catalase.
  • Findings indicate that serotonin mitigates selenium uptake and supports grapevine growth under stress conditions.
