“…Moreover, grain yield of rice plant was reduced about 10, 50 and 90 % by soil Cu level of 100, 300-500 and 1000 mg kg −1 , respectively (Xu et al 2006). Similarly, 100 mg Cu kg −1 of soil reduced the average grain yield and straw weight of the 38 rice cultivars up to 17.37 and 13.74 %, respectively, as compared to control (Yan et al 2006). The grain yield of rice significantly decreased with raising Cu (above 100 mg kg −1 of soil) levels in the soil (Xu et al 2005).…”

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 sustainable agrifood production especially in developing countries. The world's major food requirement is fulfilled through agricultural food crops. The Cu-induced losses in growth and yield of food crops probably exceeds from all other causes of food safety and security threats. Here, we review the adverse effects of Cu excess on growth and yield of essential food crops. Numerous studies reported the Cu-induced growth inhibition, oxidative damage and antioxidant response in agricultural food crops such as wheat, rice, maize, sunflower and cucumber. This article also describes the toxic levels of Cu in crops that decreased plant growth and yield due to alterations in mineral nutrition, photosynthesis, enzyme activities and decrease in chlorophyll biosynthesis. The response of various crops to elevated Cu concentrations varies depending upon nature of crop and cultivars used. This review could be helpful to understand the Cu toxicity and the mechanism of its tolerance in food crops. We recommend that Cu-tolerant crops should be grown on Cu-contaminated soils in order to ameliorate the toxic effects for sustainable farming systems and to meet the food demands of the intensively increasing population.

“…Therefore, industrial and commercial activities might contribute significantly to Cd, Cu and Ni content in the rice grains. Furthermore, the accumulation of Cd and Cu in the rice grains was reported to be remarkably varied with different cultivars (Yan et al, 2006;Yu, Wang, Fang, Yuan, & Yang, 2006).…”

“…Cu and Zn are also essential elements in plant nutrition and development. However, the presence of Cu and Zn at high concentrations induces severe phytotoxicity, resulting in the reduction of plant growth, mineral nutrient uptake, and photosynthetic activity (Salemaa and Monni, 2003;Yan et al, 2006;Borghi et al, 2007;Disante et al, 2010).…”

Willows (Salix spp.) have shown high potential for the phytoextraction of heavy metals. This study compares variations in copper (Cu) and zinc (Zn) tolerance and accumulation potential among 12 willow clones grown in a nutrient solution treated with 50 μmol/L of Cu or Zn, respectively. The results showed differences in the tolerance and accumulation of Cu and Zn with respect to different species/clones. The biomass variation among clones in response to Cu or Zn exposure ranged from the stimulation of growth to inhibition, and all of the clones tested showed higher tolerance to Cu than to Zn. The clones exhibited less variation in Cu accumulation but larger variation in Zn accumulation. Based on translocation factors, it was found that most of the Cu was retained in the roots and that Zn was more mobile than Cu for all clones. It is concluded that most willow clones are good accumulators of Zn and Cu.
