“…However, no interactions between Zn and Cd were observed in older studies (e.g. White and Chaney 1980), as was also indicated by Nan et al (2002). The status of Zn nutrition of plants may play an However, it appears that the suppressive effect of Zn supply on Cd bioavailability is the most effective at low levels of Zn in the soil or in the Zn-deficient conditions (Abdel-Sabour et al 1988, Oliver et al 1994, Choudhary et al 1995 as already low doses of Zn suppress considerably the Cd uptake.…”

1Zinc is one of the essential micronutrients required for the growth of plants. It is an integral component or activator of a number of enzymes that represent almost all enzymatic groups in plants. Zinc is highly mobile in the soil and is easily taken up by plants and thus can accumulate in the biomass up to extremely high phytotoxic concentrations (Vysloužilová et al. 2003a, b). The accumulation rate depends on soil conditions, plant species, genotype, climate and agronomic practice (Tiller 1989, Tlustoš et al. 2001. High concentrations of Zn in the soil, a frequent consequence of anthropogenic activities (Alloway 1995), affect adversely the life processes of plants (e.g. Vangronsveld and Clijsters 1994) and can result in decreased production of biomass (Vysloužilová et al. 2003a, b) ABSTRACTA pot experiment was conducted to investigate the influence of varying supplies of Zn (50-150-300 mg/kg soil -Orthic Luvisol) on the uptake of Zn by plants, selected productive parameters and production of secondary metabolites in Matricaria chamomilla L., diploid cv. Novbona. Chamomile takes up Zn easily and accumulates it in all its organs. The maximum supply of Zn resulted in an 18-fold increase in chamomile shoots where it reached the level of 271.0 mg/kg dry matter. Such a treatment resulted in a 5-fold increase of Zn in chamomile anthodia (Matricariae flos drug) reaching a level of 159.8 mg/kg dry matter. During cultivation, experimental plants showed no signs indicating an excess of Zn. Of the selected productive parameters, the increasing concentration of Zn in the soil affected significantly only the plant height. A weak, positive, insignificant effect of Zn was observed in the production of the plant biomass. When supplying Zn at a rate of 50 mg/kg soil the biomass of the shoots dry matter increased by 17% and anthodia by 8%, respectively (P > 0.05). However, an additional increase in Zn supply reduced production of anthodia, while the dose of 300 mg Zn/kg soil resulted in a significant, 17% decrease of anthodia yield in comparison with the maximum production achieved with the treatment by 50 mg Zn/kg soil. The application of Zn into the soil affected only slightly the content of essential oil and proportion of chamazulene, (E)-β-farnesene, and ene-yne-dicycloethers. An increased supply of Zn did not affect the concentration of flavone apigenin and coumarin herniarin in chamomile anthodia. Zn fertilization decreased the accumulation of Cd in chamomile plants; supply of 50 mg Zn/kg soil and caused an decrease in Cd concentration by 10% in shoots (P > 0.05) and by 37% (from 0.280 to 0.176 mg Cd/kg dry matter) in anthodia (P < 0.01), respectively. An additional increase in soil Zn decreased significantly with an accumulation of Cd by 18% (at a dose of 300 mg Zn/kg soil) only in chamomile shoots.

“…However, some studies reported no interaction between Cd uptake and Zn application (MacLean 1976, Singh and Steinnes 1976, White and Chaney 1980. The effect of Zn fertilization seems to be largely dependent on the Zn status of soils and plants and most significant effects were found when soils were Zn deficient (Oliver et al 1994).…”

Heavy metal contamination affects large areas of Europe and worldwide. Hot spots of pollution are located close to industrial sites, around large cities and in the vicinity of mining and smelting plants. Agriculture in these areas faces major problems due to heavy metal transfer into crops and subsequently into the food chain. This paper gives an overview on simple but effective countermeasures to reduce the transfer of heavy metals to edible parts of crops. Since crop species and varieties largely differ in their heavy metal uptake, choosing plants with low transfer factors (e.g., legumes, cereals) may reduce metal concentration in edible parts significantly. Cultivating crops with higher heavy metal uptake capacity, e.g., spinach or lettuce should be avoided. The application of soil amendments is another very effective measure to reduce the concentration of heavy metals in crops. Both organic (e.g., farmyard manure) and inorganic amendments (e.g., lime, zeolites, and iron oxides) were found to decrease the metal accumulation. Further effective methods to reduce metal transfer into food chain include crop rotation and cultivation of industrial or bio-energy crops. It is concluded that the methods presented here comprise several tools, which are easy to apply, and are effective to allow safe agriculture on moderately contaminated soils.

“…However, available studies have reported inconsistent results. White and Chaney (1980) reported that Cd uptake was reduced in both soybean roots and shoots through application of Zn. Eriksson (1990) found that the Zn-Cd interaction varied with the crop species.…”

SummaryA hydroponic experiment with two rice cultivars differing in cadmium (Cd) tolerance was conducted to investigate the alleviating effect of zinc (Zn) on growth inhibition and oxidative stress caused by Cd. Treatments consisted of all combinations of two Zn concentrations (0.2 and 1 lM), three Cd concentrations (0, 1, and 5 lM), and two rice cultivars (Bing 97252, Cd-tolerant; Xiushui 63, Cd-sensitive). Cd toxicity caused a dramatic reduction in plant height and biomass, chlorophyll concentration and photosynthetic rate, and an increase in Cd concentration in both roots and shoots, malondialdehyde (MDA) concentration, and superoxide dismutase (SOD) and peroxidase (POD) activities in shoots. The response of all these parameters was much larger for Xiushui 63 than for Bing 97252. Addition of Zn to the medium solution alleviated Cd toxicity, which was reflected in a significant increase in plant height, biomass, chlorophyll concentration, and photosynthetic rate, and a marked decrease in MDA concentration and activity of anti-oxidative enzymes. However, it was noted that Zn increased shoot Cd concentration at higher Cd supply, probably due to the enhancement of Cd translocation from roots to shoots. Therefore, further studies are necessary to determine the effect of Zn supply on Cd translocation from vegetative organs to grains or grain Cd accumulation before Zn fertilizer is applied to Cd-contaminated soils to alleviate Cd toxicity in rice.
