In recent years, copper (Cu) pollution in agricultural soils, due to arbitrary use of pesticides,
fungicides, industrial effluent and wastewater irrigation, present a major concern for …

The essential micronutrients for field crops are B, Cu, Fe, Mn, Mo, and Zn. Other mineral
nutrients at low concentrations considered essential to growth of some plants are Ni and Co …

The increased production and use of nanoparticles (NPs) has generated concerns about
their impact on living organisms. In this study, nCu, bulk Cu, nCuO, bulk CuO, Cu (OH) 2 …

Copper is essential for plant growth, but in excess may cause adverse effects on plant
physiology. Harmful effects are also caused by plant exposure to salinity (NaCl) due to the …

Photoinhibition of photosystem II was studied in vivo with bean (Phaseolus vulgaris) plants
grown in the presence of 0.3 (control), 4, or 15 μm Cu2+. Although photoinhibition …

Twenty-day-old cucumber plants were submitted to copper stress during 5 days. Leaf
expansion rather than dry weight accumulation was the first target of copper inhibition …

Melatonin plays an important role in stress tolerance in plants. In this study, exogenous
melatonin significantly alleviated the dwarf phenotype and inhibited the decrease of plant …

Changes in photosynthetic and antioxidant activities in maize (Zea mays L.) leaves of
cultivars 3223 and 31G98 exposed to excess copper (Cu) were investigated. Cu treatment …

The waterlogging environment generally results in the deposition of iron plaque on plant
roots, which may impact the fate of metal-based nanoparticles. Here, we investigated the …

Phytotoxicity of metals significantly contributes to the major loss in agricultural productivity.
Among all the metals, copper (Cu) is one of essential metals, where it exhibits toxicity only at …
