Feb 24, 2003· Abstract. Cadmium concentrations were much lower in barley grain than in wheat grain under comparable soil conditions. Multiple regression analysis showed that soil total Cd and pH were the significant factors influencing grain Cd concentrations. Significant cultivar differences in Cd uptake were observed for both wheat and barley.
Leafapplied sodium chloride promotes cadmium accumulation in durum wheat grain. Among the factors affecting Cd accumulation in plants, soil chloride (Cl) concentration plays a critical role. The effect of leaf NaCl application on grain Cd was studied in greenhouse .
Irrigation with untreated effluent in periurban agriculture could result in accumulation and bioconcentrations of cadmium (Cd) and lead (Pb). Different amendments were used to investigate their effect on availability, concentration, and uptake of metals by wheat in texturally different soils. Crop was irrigated with water containing Cd and Pb at 20 mg L−1, thereby adding 260 mg pot−1 of ...

Oct 10, 2017· Cadmium concentrations in all tissues of the hybrid were similar to those in its male parent yet significantly lower than those in its parent. Selenium reduced Cd accumulation in rice when Cd concentration exceeded mg kg–1; however Se accumulation depended on the levels of Cd exposure.
Oliver et al. (1993) also reported that tion with wheat in Cdcontaminated saltaffected soils wheat following lupin had higher grain Cd than wheat significantly reduced the risk of Cd transfer to wheat after wheat or barley where the crop residue was not re grain that is a main food for the Iranian people.

Cadmium and zinc accumulation in maize grain as affected by cultivars and chemical fixation amendments. Pedosphere. 21(5): 650â€"656. INTRODUCTION Heavy metal pollution of soil has an important in fluence not only on the yield and quality of crops but also on the health of humans through the food chain (Chen et al., 2000; Ownby et al ...
grain of durum wheat as compared to bread wheat was associated with a higher total uptake by the plant. Differences among plant cultivars in secretion of low molecular weight organic acids may influence root uptake of Cd (Liu et al., 2007b). In other crops, Cd may be readily taken up, but restricted translocation from root to stem and to leaves and
The prediction of grain cadmium in wheat cultures is best achieved through empirical modeling from soil parameters and soil inputs rather than through estimates of the bioavailable fractions in ...
Lead and Cadmium in Wheat Grain. ... Regional differences found in cadmium level are mainly affected by ... Statistically significant increases in cadmium accumulation from cadmium treated plants ...
Since varieties differ markedly in grainCd accumulation, efforts are needed to find traits associated with low, or high, accumulation. Two durum wheat varieties, selected in a field screening as low (Creso) and high (Svevo) grainCd accumulating, were grown on soil spiked with, 3 and mg Cd/kg.
Cadmium (Cd) accumulation in wheat genotypes of spring bread wheat (Triticum aestivum L.) and spring durum wheat (Triticum turgidum var. durum) was studied in field trials every third week throughout the growing season. The study was carried out in Sweden on .

Apr 14, 2004· Durum wheat shows considerable genotypic variation in Cd accumulation in grain [4–6]. Cadmium accumulation in grain of high and lowaccumulating nearisogenic lines was correlated with Cd accumulation in the leaves of the seedlings under field conditions . This suggests that differences in Cd accumulation in the vegetative phase may be important determinants of Cd accumulation in grain, or .
Cadmium (Cd) toxicity has varying consequences on plants growth and development. This research focused on examining the influence of Cd toxicity on fragrant rice genotypes and its consequences on yield, yield related parameters, and grain quality traits. Randomized complete block design comprising five different fragrant rice cultivars (Meixiangzhan 2, Xiangyaxiangzhan, Guixiangzhan, Basmati ...
Wheat grain Cd yield is negatively affected by elevated O 3. Effects of O 3 on wheat are more strongly related to POD 6 than to AOT40. OTC enclosure stimulates the accumulation of Cd in wheat grain as a result of enhanced transpiration.
Concentration of cadmium in durum wheat as affected by time, source and placement of nitrogen fertilization under reduced and conventionaltillage management Author: Gao, Xiaopeng, Brown, Kimberley R., Racz, Geza J., Grant, Cynthia A.
Cadmium in the durum grain ranged widely from to mg kg −1 Accumulation of Cd in grain was strongly and positively associated with soil salinity as represented by soluble chloride, soluble sulfate, or extractable Na, and also with chelateextractable Cd. Relationships to salinity were curvilinear.
Jun 01, 2006· Cadmium (Cd) accumulation in wheat genotypes of spring bread wheat (Triticum aestivum L.) and spring durum wheat (Triticum turgidum var. durum) was studied in field trials every third week throughout the growing season. The study was carried out in Sweden on three different soils and during two growing seasons.

The joint effects of Cd and Chlorimuronethyl(CE) on Cd accumulation in wheat shoot/root and SPT coefficient of Cd was carried out. Cd concentration in shoot and root increased with increasing soil Cd, but Cd concentration in shoot/root was lower than the same treatment when CE was added, and negative relationship between Cd concentration in shoot (root) and concentration of CE were ...

Grains of low Cd accumulation wheat varieties were shown to have 60%–70% lower concentrations of Cd than high Cd accumulation varieties (Hart et al., 2005). However, it may be difficult to achieve the desired effect through selective breeding alone, and a combination with other methods is required to reduce the absorption of heavy metals in cereals.
Abstract. Cadmium (Cd) accumulation in durum wheat grain is a growing concern. Among the factors affecting Cd accumulation in plants, soil chloride (Cl) concentration plays a critical role.
