Effect of silicon on the young maize plants exposed to nickel stress

A silicon particle-based courier promotes melatonin-mediated seed tolerance to nickel toxicity in rice

“…1 and 2). Moreover, the beneficial roles of Si-mediated alleviation have been reported in crop plants, like maize, 6 rice, 9,72 etc. In particular, as a typical Si-accumulating plant, rice can assimilate a great deal of Si that can amount to 10% of shoot dry biomass and mitigate various types of stress, e.g.…”

“…, drought 72 and heavy metal. 6,9,39 Therefore, high levels of Si accumulated in plants show beneficial effects on plant growth and development, but not adverse effects. In summary, we here reported one silicon particle-base method to deliver melatonin and its ameliorated effects on seed germination under Ni stress (Fig.…”

“…Besides, the concentration of Ni toxicity (250 μmol L −1 Ni) was employed according to previous reports about Ni-induced stress in rice 5 and maize. 6 Concentrations of MT and pSi-MT to tolerate Ni stress (100 μmol L −1 MT) were derived and selected based on preliminary experiments as shown in Fig. S1 †…”

“…45,46 Melatonin-alleviated or Si-mediated effects on seed germination have been reported in several plant species. 4,6,9,10,15 Nonetheless, no literature is available to depict how Si-based nanoparticles carry biomolecules, e.g. , melatonin, to pose effects on seed germination.…”

Assessing Heavy Metal Contamination Impact in Maize Growing Along the Roadside

“…Our finding regarding metal accumulation proved thata high concentration of Ni impacts chlorophyll content because Ni plays a vital role in the physiological process. Its toxicity causes reduction in photosynthesis, decrease the chlorophyll contents and affect other parameters like deficiency of water contents in leaf (Fiala et al, 2021). It may be due to human activities like extra use of fungicides, pesticides and insecticides cause toxicity ofthe soil.…”
