Influence of Silver and Copper Nanoparticles on Physiological Characteristics of Phaseolus vulgaris L. in vitro and in vivo

Silver nanoparticles elicited in vitro callus cultures for accumulation of biomass and secondary metabolites in Caralluma tuberculata

“…Determining the optimal concentration of any nano particles, at which the plant cell can attain maximum and healthy growth, is very much crucial in order to prevent the toxicity issues related to application of nanomaterial on plants. For instance, when the explants of Phaseolus vulgaris were treated with different levels of AgNPs, maximum growth parameters during callus growth such as the percent callus induction and biomass were observed at the optimum concentration (50 mg/ml) of AgNPs [26]. Literature regarding the behaviour of nanoparticles to the plant cell and tissue culture development is scare.…”

Exploring potential of copper and silver nano particles to establish efficient callogenesis and regeneration system for wheat (Triticum aestivumL.)

“…A significant increase in callus induction and callus growth rate of Phaseolus vulgaris is reported in response to exposure of explants to 50 mg/l AgNPs for 30 min, while higher concentration were found detrimental for callogenesis. 73 Fresh weight of callus is improved by silver nanoparticle treatments probably due to increased activities of antioxidant enzymes and reduced levels of reactive oxygen species. 74 …”

Composting from organic municipal solid waste: a sustainable tool for the environment and to improve grape quality

“…Copper element converts the toxicity above a threshold level based on the type of crop plants (An, 2006); on average 1 kg of dry plant tissue contains around 10 mg of Cu (Rawat et al, 2018). The toxic effects of Cu on cultivated crop plants such as mungbean (Vigna radiate L.), rice (Oryza sativa L.), lettuce (Lactuca sativa L.), mustard (Brassica nigra L.) and kidneybean (Phaseolus vulgaris L.) are denoted by inhibiting seed germination, decreases in the shoot and root lengths and morphological as well enzymatic changes; in addition, Cu toxicity has been shown to reduce the content of macronutrients in the shoot (Ca, Mg, K and P) most likely due to an interference with the uptake and translocation of the ions (Shaw and Hossain, 2013;Gopalakrishnan Nair et al, 2014;Mustafa et al, 2017;Zafar et al, 2017;Shams et al, 2018;Marastoni et al, 2019aMarastoni et al, , 2019b. The Journal of Agricultural Science 9 The vines subjected to MSW2.5 and MSW15 treatments benefited from the contribution of compost and showed an increase in the growth of the sprout, similar to the results reported by Machado et al (2021).…”
