Induction of Defense Mechanisms: Chitosan acts as a plant biostimulant, triggering the accumulation of reactive oxygen species (ROS) and calcium ions (Ca²⁺) within plant cells. These molecules serve as signaling agents, initiating physiological changes that bolster the plant’s defense responses against pathogens and environmental stresses.
Enhanced Root Development: Application of chitosan has been associated with increased root biomass and surface area. This improvement facilitates better nutrient and water uptake, contributing to overall plant vigor.
Stress Tolerance: Chitosan has demonstrated potential in enhancing plant resistance to various stresses, including drought and pathogen attacks. Its application can lead to improved photosynthetic activity and yield under stress conditions.
Chitosan is a natural biopolymer derived from chitin, found abundantly in the shells of crustaceans like shrimp and crabs. In agriculture, chitosan serves as a plant growth activator, enhancing various aspects of plant health and development.
