Salt stress is a major agricultural issue. A promising modern agriculture method is
the foliar treatment of zinc oxide nanoparticles (ZnONPs). This approach has shown
promise in boosting challenged tomato yields, fruit quality, and leaf extract antibacterial
activity against pathogens. A greenhouse experiment was conducted. The previously
synthesized and characterized ZnONPs were used to alleviate the harmful effects of
NaCl stress. Tomato fruit weight from different treatments was determined, and the
gas–liquid chromatography device was used to observe the changes in fatty acid production.
The antimicrobial activities of the aqueous and diethyl ether extracts from tomato
leaves were determined against six bacterial and six fungal strains. The plants that
were salinity-stressed and sprayed with 0.075 and 0.15 g/L ZnONPs showed a better
improvement compared to the salinity-stressed plants. Also, the sprayed plants that
were not stressed at all showed promising results compared to the control and the
other different treatments. Through the process of molecular docking, it was shown
that caffeic acid, ferulic acid, p-coumaric acid, sinapic acid, and apigenin-7-glucoside
are essential chemicals that possess antibacterial and antifungal effects against
the DNA Gyrase inhibitor and the sterol 14-alpha demethylase (CYP51) enzyme, respectively.
It is concluded that salt stress can negatively affect the growth, quality, and variant
plant features. However, the foliar application of ZnONPs is able to overcome those
adverse effects in the stressed plants, and enhance the non-stressed as well.
