Objective: To discuss the effect of cadmium concentration on the plant growth and the cadmium absorption and accumulation of Ocimum basilicum. Method: With O. basilicum as the plant materials, effects of cadmium concentration on the plant growth, cadmium accumulation, soluble sugar content, total N, P and K contents were studied on the basis of Hoagland nutrition.

It is recommended that soil contain less than 1 mg of cadmium for every 1 kg of soil. If the concentration of cadmium in your soil is greater than 20 mg/kg it would be a good idea to have your home grown produce analysed and then seek expert guidance on whether any cadmium detected constitutes a

Cadmium (Cd) is a toxic heavy metal that enters the environment through various anthropogenic sources, and inhibits plant growth and development. Cadmium toxicity may result from disturbance in plant metabolism as a consequence of disturbance in the uptake and translocation of mineral nutrients. Plant nutrients and Cd compete for the same transporters and, therefore, presence of Cd results in

No or little difference in Cd tissue concentration between the +Mg and -Mg plants was observed, suggesting that lower Cd toxicity was probably not attributable to modified root to shoot translocation. Mg deficiency also promoted an increase in the iron (Fe) concentration (up to

Cadmium in food comes to a large extent from atmospheric cadmium as a result of foliar absorption or root uptake of cadmium deposited on soils. Foliar absorption is determined by dry or wet deposition rates of cadmium and uptake of cadmium by plants from soils is primarily controlled by the concentration of cadmium in soil solution.

Cadmium concentration and plant tolerance to Cd: Our data demonstrate that higher metal exposures led to remarkable Cd accumulation in both root and shoot tissues, hence leading to a high degree of toxicity, which is in agreement with results reported by other authors (e.g., Carneiro et al., 2002; Lima et al., 2006; Mishra et al. 2006).

Effect of cadmium on the plant growth: Cadmium is not an essential nutrient and at high concentration inhibits plant growth (Anita et al ., 1990; Aery and Rana, 2003).

These changes allowed WT plants to maintain turgor when exposed to 1 μM CdCl 2, but at 4 μM CdCl 2 leaf turgor of WT plants was significantly less than in SGECd t mutant plants ( Fig. 3D ).

If the concentration of cadmium in your soil is greater than 20 mg/kg If soil cadmium levels are elevated, grow plant varieties that take up less cadmium; Leafy vegetables like lettuce, cabbage and spinach take up the most cadmium.
Get PriceCadmium is taken up by plants from soils and translocated with subsequent transfer through the terrestrial food chain (Shore and Douben, 1994). The most important soil factors influencing plant cadmium accumulation are soil pH and cadmium concentration. Soil cadmium is distributed between a number of pools or

Cadmium concentrations in maize and ryegrass were negatively related to the product of cadmium in soil and pH (Tudoreanu and Phillips, 2004). A positive coefficient between soil pH and cadmium in ryegrass may derive from ionic competition, for example, sodium has been demonstrated to increase plant cadmium (Chiy and Phillips, 1999).

Cadmium (Cd) is toxic to plants, animals, and humans. However, different plant species growing on the same soil may have very different shoot Cd concentrations depending on properties such as size of the root system, Cd net influx, shoot‐growth rate, Cd translocation from root to shoot, and the ability to affect Cd availability in the soil.
