UV-A Radiation Stimulates Tolerance against Fusarium oxysporum f. sp. lycopersici in Tomato Plants

UV-A radiation is a tool that has stimulant action in plants and can be used to induce benefits through the production of bioactive compounds synthesis secondary metabolites, among others. Particularly, its application could stimulate tolerance biotic stress caused by Fusarium oxysporum f. sp. lycopersici (Fol) tomato plants; for this reason, aim present study was evaluate ability against Fol. For this, crop established which two conditions supplementation with were tested on inoculated fungus The pathogen’s impact agronomic parameters, incidence severity, contents biomarkers, metabolites photosynthetic pigments determined. results show pathogen severity about 60%; therefore, fruit yield also negative (−31%). Moreover, significantly impacted content positive control increased H2O2 (+23.9%), malondialdehyde (+41.7%) proline (+54.8%). In contrast, decreased Fol (−35.5%), prevented effect plant/fruit yield. addition, biomarkers (−10.4% O2•−, −22% H2O2, −16% MDA), (+13.2% flavonoids, +35% anthocyanins) (+17% β-carotene, +12% yellow pigments, +19.8% total chlorophyll) pathogen. From obtained, it concluded good alternative means attack pathogens such as plants, without adverse consequences environment or crop.
