Salicylic acid has multiple uses in agriculture, primarily improving plant stress tolerance, inducing disease resistance, regulating growth and development, and aiding fruit preservation:
1. Improving Plant Stress Resistance
Salicylic acid can significantly enhance plant resistance to cold, drought, salt, and heat.
2. Inducing Disease Resistance
As a signaling molecule, salicylic acid activates plant defense mechanisms, promoting the synthesis of antimicrobial substances such as pathogenesis-related proteins (PR proteins) and phytoalexins, enhancing cell wall lignification, and preventing pathogen infection. For example, when rice is subjected to stress, salicylic acid enhances stress tolerance by regulating the jasmonic acid metabolic pathway.
3. Regulating Growth and Development
Promoting seed germination: Breaking seed dormancy and improving hormone balance and enzyme activity.
4. Affects Root Growth: Low concentrations promote root development, while high concentrations inhibit it.
5. Regulates Fruit Ripening: Promotes ethylene synthesis, accelerating ripening and inhibiting decay.
6. Aids Fruit Preservation: Spraying salicylic acid can reduce fruit respiration and ethylene production, delaying aging and decay. For example, apples sprayed with salicylic acid have a longer shelf life.
