Accumulation of Stinging Nettle Bioactive Compounds as a Response to Controlled Drought Stress

As the impact of global warming intensifies drought effects, plants need to adapt and other climate change-induced stresses through various defense mechanisms. One them is increased synthesis bioactive compounds (BCs), which helps overcome adverse environmental conditions. This effect can be used in sustainable controlled cultivation as a tool for nutritional improvement crops, so this study focused on growing stinging nettle (Urtica dioica L.) human consumption environment. Since consumed green leafy vegetable due its value, aim was determine content BCs (ascorbic acid, phenolic compounds, pigments) antioxidant capacity leaves grown under different stress conditions an ebb flow hydroponic system. During experiment, were treated with nutrient solution adjusted 1 hour then exposed three intervals: 24, 48, 96 h. 48 h interval, accumulated highest amounts total non-flavonoid (400.21 237.33 mg GAE/100 g, respectively), during amount ascorbic acid (96.80 mg/100 g fw). The recorded 24 treatments (2435.07 2444.83 µmol/TE, respectively) according ABTS treatment (3773.49 µmol/TE) FRAP assay. obtained results show that durations caused by absence solutions have positive accumulation BCs.
