DetailsAbstract Copper is an essential element for plants, but its higher concentration can make disruption in plant growth. The current study was conducted to determine the impact of excess copper (Control 0.2, 200 and 400 µM of copper sulfate) on growth, chlorophyll content, nutrient uptake and enzyme activity in lettuce. The results of …
DetailsHowever, for another type of plants, this higher zinc concentration can cause leaf chlorosis (Qiao et al. 2019), inhibition of growth (Baker and Walker 1990), or inhibition of photosynthesis (DalCorso et al. 2013). Higher concentration of Zn can inhibit plant growth, especially growth of roots, which was observed by Sresty and Madhava …
DetailsCopper (Cu) is essential to plants but can also be harmful due to Fenton chemistry. Because of that, it is necessary to keep Cu within a narrow concentration limit. Plants evolved mechanisms to sense Cu and precisely regulate uptake and accumulation to avoid both deficiency and toxicity. However, plants experience variable Cu levels in …

DetailsCopper is absorbed from the soil by plants in a manner similar to iron uptake by dicotyledonous and non-gramineous monocotyledonous plants. Copper ions can bind to cell walls and the outer membrane surface of plant root cells, where Cu 2+ is reduced to Cu + by Fe reductase oxidase (FRO4/FRO5), and the reduced Cu + is transported across …
DetailsAlthough copper is essential for plants, excessive concentrations can be toxic, impeding plant growth and nutrient uptake, and inducing oxidative stress.
DetailsThe specific energy was equivalent to 151 MJ/t of ore. This figure was more than twice the average value of electricity consumption at a concentration copper plant in Chile for 2015 (80.8 MJ/t ore) as reported in Ref. [71]. If the specific energy is expressed by a ton of metal concentrate, this value was 34278 MJ/t.
DetailsCopper (Cu) is an essential micronutrient for plants because it participates in several redox reactions and the structural constitution of the Fe–Cu cluster. Although it is required in …
