The Impact of Salinity Stress on Antioxidant Response and Bioactive Compounds of Nepeta cataria L.

In this study, the ability of Nepeta cataria L. to grow and synthesize bioactive compounds on soil treated with different salt concentrations was tested evaluate opportunity cultivating it in soils affected by salinization. N. grown containing specific amounts NaCl, Na2SO4, their mixture. After harvesting, plants were analyzed from morphological physiological point view. Salinity stress inhibited growth, highest decrease plant yield up about 70% case mixture, smaller values for separate treatments. same time, as a defense mechanism, there an increase granular trichomes’ density, observed scanning electron microscope. For mild salt, amount chlorophyll pigments enhanced, while stronger salinity stress, decreased. The opposite behavior evidenced polyphenol content, antioxidant activity used protective mechanism against reactive oxygen species produced under stress. considerably higher NaCl Na2SO4 treatments than mixture variants. results showed that reacts well high levels, increased content even studied conditions.
