“…Under the same Cd level, shoot Cd concentrations showed great variability among 50 tested pakchoi cultivars, and similar findings were reported on rice (Liu et al, 2003a;2003b;Yu et al, 2006), wheat (Stolt et al, 2006), maize (Kurz et al, 1999), asparagus beans , and Chinese cabbage (Liu et al, 2009;2010). These results demonstrate that genetic variability for Cd accumulation exists within a species and this fact makes it possible to select and breed Cd-PSCs.…”

“…According to the standards for the identification of Cd-PSCs put forward by Liu et al (2009) with some modification, six pakchoi cultivars with low Cd accumulation were selected, and were further tested in a field experiment. Randomized block design with four replications was used in the field experiment.…”

“…There are both natural and anthropogenic sources of Cd in soil, including shortor long-range mining, atmospheric deposition, irrigation water, utilization of fertilizers, and application of municipal sewage-wastes, compost sewage sludges, and manures (Das et al, 1997;Arduini et al, 2006;Singh et al, 2006). In China, with the development of modern industry and agriculture, Cd has posed a serious problem for safe food production, and at least 13 330 ha of farmland has been contaminated by varying levels of Cd (Liu et al, 2009). It is therefore urgent that environmental and soil scientists to identify suitable approaches for reducing Cd accumulation in food crops.…”

“…chinensis), a cruciferous leafy vegetable, is widely planted in China, especially in southern China; identification of pakchoi genotypes with low Cd accumulation for food safety is therefore especially important. Variations in Cd concentration among cultivars have been reported in some vegetable species, including carrot (Harrison, 1986), cucumber (Harrison and Staub, 1986), lettuce (Thomas and Harrison, 1991), potato (Dunbar et al, 2003), and Chinese cabbage (Liu et al, 2009;2010). However, to our knowledge, there is limited information on the screening of Cd-PSCs in pakchoi.…”

Abstract:The selection and breeding of pollution-safe cultivars (PSCs) is a practicable and cost-effective approach to minimize the influx of heavy metal to the human food chain. In this study, both pot-culture and field experiments were conducted to identify and screen out cadmium pollution-safe cultivars (Cd-PSCs) from 50 pakchoi (Brassica rapa L. ssp. chinensis) cultivars for food safety. When treated with 1.0 or 2.5 mg/kg Cd, most of the pakchoi cultivars (>70%) showed greater or similar shoot biomass when compared with the control. This result indicates that pakchoi has a considerable tolerance to soil Cd stress. Cd concentrations in the shoot varied significantly (P<0.05) between cultivars: in two Cd treatments (1.0 and 2.5 mg/kg), the average values were 0.074 and 0.175 mg/kg fresh weight (FW), respectively. Cd concentrations in the shoots of 14 pakchoi cultivars were lower than 0.05 mg/kg FW. In pot-culture experiments, both enrichment factors (EFs) and translocation factors (TFs) of six pakchoi cultivars were lower than 1.0. The field studies further confirmed that the Hangzhouyoudonger, Aijiaoheiye 333, and Zaoshenghuajing cultivars are Cd-PSCs, and are therefore suitable for growth in low Cd-contaminated soils (≤1.2 mg/kg) without any risk to food safety.

“…Plants may also facilitate the immobilization mechanisms in the rhizosphere that reduce trace element mobility. Studies on plants to stabilize heavy metal in soil have shown significantly differences in the absorption of heavy metals among varieties of the same species [10,14,15,16,17]. Selecting plant varieties with low absorption of heavy metals is important to reduce the risk of heavy metal exposure.…”

Patterns of cadmium uptake and accumulation by exclusion and inclusion soybean cultivars

In the areas where the soils are polluted by cadmium (Cd), farmers cannot afford to use their lands for remediation due to high demand for soybean (Glycine max L.) production. In order to provide information for safe soybean production and achieve the phytoremediation using the root at the meantime, four soybean cultivars (mentioned as Cd excluder and Cd includer) differing in seed Cd accumulation were grown in a mixed growing media treated with different Cd concentrations (0 and 0.35 mg kg −1 ) in a growth cabinet. The biomass and Cd concentration in roots, stems, leaves, pods, and seeds were measured at the beginning of seed development (R5) and maturity (R8) stages; accumulation coefficient and translocation coefficient of Cd in different organs were calculated. Cadmium concentration in seeds was positively correlated with the Cd concentration in stem, leaf, and pod. Cadmium concentration in the roots of the Cd excluder was significantly higher than that in the Cd includer at the R5 and R8 stages; however, the Cd concentration in the seeds of the Cd includer was higher than that in the Cd excluder. Compared with the Cd excluder, more Cd was transported from the root to the aboveground organs of Cd includer. This suggests that Cd excluder with high cadmium accumulation in the root and low accumulation in the seed could provide a possible way to develop Cd-safe cultivars with high phytoremediation capacity when grown on Cd-polluted lands.
