Abstract : Resveratrol (3,4',5-trihydroxystilbene) is one of the most important polyphenol compounds present in the human diet. From the aspect of agricultural production, resveratrol is also an important component. Grapevine plants produce it as a secondary metabolite that is synthesized to the greatest extent in stressful conditions. These conditions include abiotic and biotic factors such as a lack or excess of water, the content of micro and macro elements in the soil, agrotechnical measures, infections caused by phytopathogenic microorganisms, the presence of chemical stressors such as heavy metals, intensive application of plant protection products (PPP), uncontrolled application of synthetic fertilizers, etc. The most important stressor is infections caused by phytopathogenic organisms, especially the fungus Botrytis cinerea, whose presence is a trigger for the synthesis of resveratrol. With the intensive resveratrol production, plants activate the induced defense system, which inhibits the growth and further progression of pathogens. Often, the concentrations of synthesized resveratrol in infected plants are not sufficient to completely suppress pathogens, but they certainly slow down and keep infections at a low level, to provide additional time for us to use adequate protection measures. In addition to the plants that produce it, its application is also possible in the form of a water solution of pure resveratrol that can be applied during the storage of agricultural products to preserve their freshness as long as possible and to reduce the use of PPP in storages. In this paper, an overview of the last references was given to gain an overall picture of how important resveratrol is and how much potential it has from the aspect of human health and plant protection.
