Attenuating Effect of an Extract of Cd-Hyperaccumulator Solanum nigrum on the Growth and Physio-chemical Changes of Datura innoxia Under Cd Stress

Abstract Purpose The use of plant extracts obtained from plants that are highly tolerant to heavy metal toxicity has been beneficial in improving the growth grown under conditions. A lab experiment was performed elucidate alleviating role foliar applied cadmium (Cd)-hyperaccumulator Solanum nigrum ( S. ) extract on Datura innoxia D. Cd stress (0, 50, and 100 mg kg -1 soil). Methods Growth parameters, photosynthetic pigment content, osmo-metabolic compounds, reduced glutathione phytochelatins oxidative damage, lignin content its related enzyme (cell wall-bound peroxidase, POX) were determined. Results Apart application response leaf (SNE) either exposed or non-Cd plants, parameters both concentrations (50 soil) terms root shoot fresh, dry weight, length, area noticeably diminished by 29 51%, 54%, 35 70%, 40 53%, 30 69%, 60%, 11 23%, respectively, compared with untreated control plants. Foliar delivered SNE secured pigment, free amino acids, soluble proteins, sugar content. Additionally, it lessened adverse effects curtailing hydrogen peroxide (H 2 O malondialdehyde (MDA) 28 27%, 21 subjected 50 only. findings herein indicated water their interactions investigated rates significantly augmented phenolics, alkaloids, Cell wall stiffening POX higher soil displaying increase values 275 300%, against treated control. magnitude increment imposed using reflects adequate cell advocated limited lignification, downregulated activity. Owing application, leaves contents efficiently reflecting apparent liveliness non-treated Cd-stressed Conclusions outcomes this study designate Cd-hyperaccumulator can be counted as an unconventional innovative approach alleviation employed integrated practice when Cd-contaminated regions exploited for sustainable agriculture multipurpose
