Pb-Stress Induced Oxidative Stress Caused Alterations in Antioxidant Efficacy in Two Groundnut (<i>Arachis hypogaea</i> L.) Cultivars

“…A pronounced increase in proline content has been noticed in Solanum nigrum [55], and wheat [5], when the plants were exposed to heavy metals. Similarly, in the present study, the proline content was increased in leaves and roots of both cultivars with increasing concentration of Pb.…”

“…The hot spots of soil contamination are located in the regions of large industrial activities, where surrounding agricultural lands are affected by the deposition of heavy metals and also agricultural practice, e.g., application of sewage sludges, phosphate fertilizers, liming, irrigation water and pesticides has lead to increased heavy metal concentration in soils [2]. The long time persistent nature of some heavy metals, such as Pb and Cd are leading to hazardous accumulation [3], and a huge variation in metal tolerance was observed between different crop plants [4] [5].…”

“…The effect of Pb mainly depends on concentration, soil type, soil properties and plant species [6]. Heavy metal induced phytotoxicity or plant tolerant responses to heavy metal stress is a complex phenomenon, involving developmental changes as well as physiological and biochemical mechanisms [5] [7] [8].…”

Screening Indian Mustard Genotypes for Phytoremediating Arsenic‐Contaminated Soils

“…The current literature suggests that seed germination is affected by metals or metalloid in two ways, by their general toxicity in addition to several nutritional disturbances and by their inhibition of water uptake, respectively. Most papers show that metal treatment causes a concentration-dependent reduction in germination in many species [32][33][34][35]. Given the above, we inferred that Pusa Jai Kisan germinated so well than Pusa Basant, which might be following reasons: (1) the seeds of Pusa Basant could be more affected by As and get to early crack down of seed coat of this genotype than that of Pusa Jai Kisan, hence, metal toxicity took placed several nutrition disturbances in side seed, (2) therefore, metal perniciousness could be suppress water uptake in the seed of Pusa Basant in compression of Pusa Jai Kisan and taken advantage Pusa Jai Kisan germinated good than Pusa Basant.…”

Screening of damage induced by lead (Pb) in rye (Secale cereale L.) – a genetic and physiological approach

“…In plants, toxic levels of Pb cause damage to different cellular functions, including targeting metal ions in functional groups of macromolecules, photosynthesis, regulation of water capacity by altering related enzyme activities and mineral nutrient metabolism.
