Salicilatos na agricultura: uma revisão bibliográfica

Abstract

Due to its ability to increase plant resistance to different types of biotic and abiotic stresses, salicylic acid (SA) has gained popularity in agriculture. Although it is a common phytohormone in plant physiology, this substance has become known as a promising tool for maximizing agricultural production. This review highlights the role of AS in agriculture, highlighting its use in crops of economic importance, such as coffee, sugar cane, corn, soybeans and cotton. Increasing environmental pressure and climate change have hampered contemporary agriculture. To ensure food security, different strategies are necessary and the use of substances that induce plant resistance to stress is essential in this context. AS can be a solution, as it can trigger complete physiological responses in plants. Such as hypersensitive (HR), a form of defense that provides localized immunity against pathogens. Furthermore, it increases the production of pathogen response proteins, which strengthens systemic acquired resistance (SAR). Thus, AS is an essential ally for the modernization of agriculture, offering an innovative way to increase plants' natural defenses. Deep understanding of how it affects plant physiology helps farmers improve the resilience of their crops. Therefore, effective incorporation of AS into agricultural practices increases productivity and enhances adaptation of the agricultural ecosystem.
