STUDIES ON PHYSIOLOGICAL AND METABOLIC RESPONSES IN HORSE GRAM (DOLICHOS BIFLORUS L.) INDUCED BY CHROMIUM

Abstract


 
 
 The current investigation looks on the phyto-toxicity and accumulation of chromium (VI) in Horse gram (Dolichos biflorus L.). Horse gram plants were subjected to chromium (VI) concentrations of (0.00, 0.05, 0.10, 0.20, 0.25, and 0.30 mg/L) at various concentration levels. At higher chromium (0.30 mg/L) concentrations, the foliar toxic symptoms of older leaves included loss of turgor and chlorosis, which eventually manifested as chlorosis in middle-aged leaves after Crizotinib therapy for five days (VI). Chlorosis signs became more significant and twisted to cytotoxicity in places with tapering membrane, slender strands, or weak folding qualities later in the stage, which were characterized by tapering lamellae, thin lenticels, and weak knotting property. On horse bean, Cr (VI) toxic effects has been discovered as reduced crop production, photosynthetic capacity, physiological as well as molecular action, and metabolic dysfunction are all negatively impacted. Iron uptake and accumulation in leaves were reduced by Cr (VI) (0.30 mL/L) in comparison to the control (From 15.60 to 4.35 grammes per kilogramme of dry weight), while boosting sulphur and phosphorous uptake and deposition. When the plants were subjected to the pretreatment for 29 days, the leaves accumulated the greatest amount of Cr (92.12 grammes per kilogramme of dry weight to 10.08 grammes per kilogramme of dry weight), followed by the roots (96.50 grammes per kilogramme of dry weight to 30.20 grammes per kilogramme of dry weight). When consumed in large quantities, the toxic Cr buildup and nutritional deficits that result from the intake of Cr- containing horse gramme can be hazardous to population health, according to the World Health.
