Salinity stress-induced impacts on biomass production, bioactive compounds, antioxidant activities and oxidative stress in watermeal (Wolffia globosa)
Abstract This study investigated the impact of salinity stress on the biomass production, proximate composition and bioactive contents, antioxidant activities, and oxidative stress parameters of Wolffia globosa. Wolffia was exposed to variable NaCl concentrations (0, 8.56, 17.11, 25.67, 34.22, and 4...

| description | Abstract This study investigated the impact of salinity stress on the biomass production, proximate composition and bioactive contents, antioxidant activities, and oxidative stress parameters of Wolffia globosa. Wolffia was exposed to variable NaCl concentrations (0, 8.56, 17.11, 25.67, 34.22, and 42.78 mM) in nutrient-replete nutrient conditions under natural sunlight in a transparent polyhouse. The net biomass gain (NBG; 131.17 g), crude protein (33.16%) and crude lipid content (4.9%) were significantly high at 8.56 mM NaCl compared to control and most of other treatments. Total phenolic content peaked at 17.11 mM NaCl (551.39 mg GAE g−1), while total tannin content was highest at 25.67 mM NaCl (13.38 mg TAE g−1). Total flavonoid content, vitamin C, oxidative stress enzymes; superoxide dismutase, catalase, and lipid peroxidation (malondialdehyde, MDA) peaked at 42.78 mM NaCl, with values of 140.52 mg QE g−1, 218.69 mg 100 g−1, 28.18 U g−1 FW, 288.60 U min−1 g−1 FW, and 142.32 mg MDA kg−1, respectively. The control invariably had the lowest values. Total carotenoid content was significantly higher at 17.11 and 25.67 mM NaCl (1812.84 and 1749.10 μg g−1), while Chlorophyll-a (Chl-a) was highest at 17.11 mM (21.33 μg g−1). Chlorophyll-b (Chl-b) peaked at 17.11, 25.67, and 34.22 mM NaCl levels. Salinity stress generally elevated antioxidant activities, assessed via DPPH, ABTS, and FRAP assays reaching their highest values at 34.22 mM NaCl (40.52%), 17.11 mM NaCl (56.71%), and 25.67 mM NaCl (428.83 μmol Fe2⁺ g−1), respectively. FT-IR profiles indicated changes in chemical composition and functional groups due to salt stress. Overall, salinity significantly influenced the proximate composition, antioxidant activities, bioactive compounds and oxidative stress enzyme activities of wolffia. |
