Treatment of Black-Odorous Water Using Submerged Plants: The Physiological Response of Vallisneria natans

The main aim of this research was to determine the physiological response submerged macrophyte Vallisneria natans (V. natans) black water with a foul odor. V. chosen as experimental plant species investigate morphological and ecophysiological adaptation methods in varying light depths black-odorous water. planted tap (D), two types (E F), under three distinct conditions (low light, medium high light). In high-light condition (E), biomass content declined from 1.78 g on 14th day 1.49 28th day, demonstrating that inhibited growth natans. Under stress water, chlorophyll increased greatly early period but reduced during latter period. However, 21st maximum 1.30 mg/g (E) 1.18 (F) observed. addition, malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), peroxidase (POD) activity monitored reported results work demonstrated conclusively odorous exerts certain development Future should incorporate evaluation several vary process environmental produce field-relevant, dependable results.
