Growth, nutrient uptake and enzyme activity response of Lettuce
Abstract 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 …

Copper-Induced Responses in Different Plant Species
The high concentration of copper suppresses biomass accumulation and linear plant growth. Copper affected root growth stronger than shoot growth. The reduced mobility of Cu in soil is due to its strong binding to organic and inorganic colloids, where it acts as a barrier to Cu toxicity in terrestrial plants.
