Interactive Effects of Cadmium and Zinc Application on Their Uptake by Rice Under Waterlogged and Non-waterlogged Conditions
In order to investigate the effect of Cd and Zn on uptake, concentration and the translocation factor of the Cd and Zn in the rice plant, a factorial experiment was conducted with four factors including two rice cultivars of Vandana and Hashemi, two waterlogged and non-waterlogged conditions and three levels of Zn and Cd (0, 5 and 10 mg kg-1 soil). The experiment was carried out in a randomized...
متن کاملeffect of copper and zinc on the uptake of cadmium by corn and sunflower
abstract heavy metals enter to human food chain through the plant and soil contamination. it is very important to evaluate the affecting factors on plant uptake of heavy metals. in this study the effects of copper and zinc availability on cadmium uptake of root and shoot of corn and sunflower was investigated. the experiment was carried out with a factorial arrangement, two species of plants (s...
متن کاملCopper uptake by four Elsholtzia ecotypes supplied with varying levels of copper in solution culture.
The effects of copper (Cu) on the yield and Cu uptake of three ecotypes of Elsholtzia splendens and one of Elsholtzia argyi were studied using solution culture. Three Cu concentrations were compared: 0.31 (control), 50 and 100 micromol L(-1). Although E. argyi took up more Cu in the aboveground parts, typical visual symptoms of Cu toxicity appeared when the plants grew in 50 and 100 micromol Cu...
متن کاملCadmium uptake by plants.
Food chain contamination by cadmium (Cd) is the most important pathway of Cd exposure to the general population, excluding smokers. Factors affecting transfer of Cd from soil and air to plants are reviewed. The direct deposition of airborne Cd in the plants has only a marginal influence on the crop Cd concentrations in rural areas with low atmospheric Cd deposition, i.e. < 2 g Cd ha(-1) y(-1). ...
