“…Cadmium accumulation and distribution in plants differ with species and among cultivars within a species (Page et al 1972;Bingham et al 1975;Pettersson 1977;Chang et al 1982;Kuboi et al 1986;Yang et al 1995). Cadmium concentration of plants grown in solution culture increased in the order: oats, wheat < bean, pea, sunflower, cucumber < corn, mustard < radish, kale, rape < tomato, carrot, sorrel < lettuce (Pettersson 1977).…”

“…Although plants do not require Cd for growth or reproduction, the bioaccumulation index of Cd in green plants exceeds that of all other trace elements (Kabata-Pendias and Pendias 1992). Plants can accumulate relatively high levels of cadmium, without adverse effects on growth (Bingham et al 1975;Bingham 1979;Kuboi et al 1986). Cadmium is retained for many years in the human body, so consumption of foods high in Cd may induce chronic toxicity (Jackson and Alloway 1992;FAO/WHO 1995).…”

Cadmium is a heavy metal present in soils from natural and anthropogenic sources. Plant uptake of Cd at levels present in the soil solution is dependent on a system that is largely metabolically mediated and competitive with the uptake system for Zn and possibly other metals. Much of the Cd taken up by plants is retained in the root, but a portion is translocated to the aerial portions of the plant and into the seed. The amount of Cd accumulated and translocated in plants varies with species and with cultivars within species. Soil, environmental and management factors impact on the amount of Cd accumulated in plants. Potential methods of reducing the accumulation of Cd in crops include reduction of Cd input to the soil system, site selection, management practices which decrease the concentration of Cd in the soil solution and its uptake and translocation by plants, and development and production of plant cultivars with the genetic tendency for low Cd uptake.

A b s t r a c tHeavy metals are among the most common contaminants of agricultural lands. Cleaning (remediation) of such territories is extremely difficult or impossible. A promising approach for the production of environmentally friendly products of crop industry in the contaminated soils can be a selection of varieties with reduced accumulation of heavy metals. The aim of this work was to study the variability of pea in accumulation and transport of heavy metals from shoots to seeds and to identify varieties with low accumulation of heavy metals from contaminated soils. The objects of research were 30 varieties of pea (Pisum sativum L.) from the collection of Federal Research Center N.I. Vavilov All-Russia Institute of Plant Genetic Resources (St. Petersburg). The pot experiment was carried out in summer in a greenhouse with natural light and temperature (All-Russian Research Institute of Agricultural Microbiology, St. Petersburg). Pea seeds were surface-sterilized and scribbled with concentrated H 2 SO 4 for 30 minutes and germinated for 3 days at 22 C in Petri dishes with wet filter paper. The seedlings were planted in pots (5 seedlings per pot, 3 pots for each genotype) containing 5 kg of sod-podzolic fallow soil. Ten days before seed sowing the soil was enriched with heavy metals in the form of chlorides (mg/kg): . At the same time, fertilizers were applied (mg/kg): NH 4 NO 3 -15, KNO 3 -200, KH 2 PO 4 -200, MgSO 4 -30, CaCl 2 -20, H 3 BO 3 -3, MnSO 4 -3, ZnSO 4 -3, Na 2 MoO 4 -1.5. The plants were grown until the seed maturing phase, dried and ground to a powder. Samples (separately shoots and seeds) were digested in a mixture of concentrated nitric acid and 38 % H 2 O 2 . The content of heavy metals and nutrients was determined using ICPE-9000 spectrometer (Shimadzu, Japan). The studied samples differed significantly in the content of heavy metals in shoots and seeds that indicated a high variability of pea in the accumulation of heavy metals and their transport from vegetative to reproductive organs. The variability values for shoots and seeds were comparable in magnitude, but did not correlate with each other. The shoots or seed contents of various heavy metals, as well as nutrients, in many cases positively correlated, which could be due to the diversity of molecular transport channels in plants and their low specificity. There was positive correlation between the content of elements in shoots and seeds for Cd, Co, Cr, Ni, P, Sr, and negative was found between the shoot and seed contents of Zn and K. The results indicate specific mechanisms of transport of individual elements from shoot to seed and the barrier for abiogenic metal transport from vegetative to reproductive organs. The effectiveness of these mechanisms depends significantly on the plant genotype. The possibility of selection of pea varieties with a low content of many heavy metals simultaneously is shown. Pea varieties k-188, k-1027Pea varieties k-188, k- , k-1250Pea varieties k-188, k- , k-2593 are recommended for use in selection prog...

“…Les effets du P semblent venir de l'incidence de l'engrais phosphoré sur la densité et la vigueur des peuplements plutôt que de la présence d'impuretés de Cd dans l'engrais. plant growth, plants can absorb and accumulate it to various levels without adverse effects on growth (Kuboi et al 1986). However, Cd tends to accumulate in the body of mammals, and is considered to be one of the most hazardous elements for humans (Kuboi et al 1987).…”

. 2003. Effects of source and placement of phosphorus on concentration of cadmium in the grain of two durum wheat cultivars. Can. J. Plant Sci. 83: 475-482. Cadmium is toxic to humans. Because it enters the food chain through plant uptake, application of phosphorus fertilizer carrying Cd as an impurity may increase the Cd concentration of cereal grains above proposed threshold values. Field experiments were conducted to determine the effect of two phosphorus fertilizers on Cd concentration of two durum wheat (Triticum turgidum L. var. durum) cultivars, a low Cd accumulator (Arcola) and a high accumulator (Kyle) grown in two soils of southwestern Saskatchewan, Canada. Phosphorus was applied as monoammonium phosphate (15 mg Cd kg -1 ) and as triple superphosphate (75 mg Cd kg -1 ) at a rate of 18 kg P ha -1 . The fertilizer was applied in a mid-row band or in the seed row. Nitrogen was applied as urea or as ammonium sulphate. Variability in Cd concentration was attributed primarily to genotype and environment, which accounted for 41% and 29% of the explained variability, respectively. The Cd concentration of Arcola averaged 80 µg kg -1 , while that of Kyle averaged 143 µg kg -1 . In contrast, fertilization accounted for only a small proportion of the explained variability, with phosphorus treatments accounting for 3% of the model sums of squares, and N sources accounting for less than 1%. Phosphorus fertilization increased the Cd concentration of Arcola, regardless of source or placement, but the proportion of samples with Cd concentration above 100 µg kg -1 remained unchanged at 17%. In the case of Kyle the Cd concentration increased only when the fertilizer was seed-placed, but in this case the proportion of samples with Cd concentration above 100 µg kg -1 increased from 67 to 90%. The effect of P appeared to result from the effects of fertilizer on plant density and vigour rather than from Cd impurities in the fertilizer.Key words: Cadmium concentration, cadmium uptake, durum wheat, fertilization, phosphorus, fertilizer placement, phosphorus source Selles, F., Clarke, J. M., Zentner, R. P. et Campbell, C. A. 2003. Incidence de la source et de la méthode de placement du phosphore sur la concentration de cadmium dans le grain de deux cultivars de blé dur. Can. J. Plant Sci. 83: 475-482. Le cadmium (Cd) est toxique pour l'être humain. Comme cet élément entre dans la chaîne alimentaire par les végétaux, qui l'assimilent, l'usage d'engrais phosphorés contenant du Cd sous forme d'impuretés pourrait porter la concentration de cet élément au-delà du seuil de tolérance recommandé dans le grain des céréales. Les auteurs ont procédé à des essais sur le terrain pour vérifier l'incidence de deux engrais phosphorés sur la concentration de Cd dans deux cultivars de blé dur (Triticum turgidum L. var. durum), soit un cultivar accumulant peu cet élément (Arcola) et l'autre l'accumulant beaucoup (Kyle). Les deux variétés ont été cultivées sur deux sols du sud-ouest de la Saskatchewan, au Canada. Aux fins de l'expérience, les aute...
