Glutathione: A Key Ally in Plant Health

 

In modern agriculture, ensuring crop health in the face of challenges such as climate change, water stress, and pathogens is a top priority. In this context, glutathione, a natural compound present in plants, emerges as a key element in plant stress response.

This tripeptide, composed of glutamic acid, cysteine, and glycine, acts as a powerful antioxidant and plays a vital role in numerous physiological processes that strengthen crop resilience. Its main function is the detoxification of free radicals and reactive oxygen species (ROS), which accumulate under adverse conditions such as drought, salinity, or extreme temperatures.

In addition, glutathione plays a fundamental role in tolerance to abiotic stress and in the detoxification of heavy metals through the formation of phytochelatins. It is also closely linked to sulfur metabolism and the synthesis of essential compounds for proper plant development.

Sultech Biostimulants: Activating Natural Plant Defenses

In this context, AFEPASA’s Sultech biostimulants are designed to optimize the availability of sulfur in easily assimilable forms. This nutrient is essential for the formation of cysteine, the most limiting amino acid in glutathione synthesis.

By ensuring a balanced sulfur supply, Sultech biostimulants promote the natural production of glutathione, strengthening the plant’s antioxidant system and improving its ability to cope with stress conditions.
