“…It was also claimed by Kratochvil et al [55] that luxury consumption of P does occur in agronomic species produced on P-enriched soils. A strong positive correlation was found between the P content in wheat grain and straw (Table 9), as was also reported by Shi et al [56], as well as between P content in grain and in post-harvest residues. Winter wheat (experiments III and IV) showed a noticeably lower P content in grain than spring wheat (experiments I, II and V), which may be linked to a dilution effect [57] due to the higher yield of winter wheat grain (7.07-9.78 t/ha) as compared with spring wheat (4.18-6.70 t/ha).…”

Facing phosphate rock scarcity, growing food requirements and pollution problems with phosphorus (P)-containing waste, re-using P as fertiliser is becoming a real need. Innovative fertilisers from sewage sludge ash, animal bones and blood, activated by phosphorus solubilising microorganisms (PSM), were tested in field experiments with winter or spring wheat and compared with commercial fertilisers (superphosphate, phosphorite). Three levels of P doses were established (17.6, 26.4 and 35.2 kg/ha). This paper discusses the fertilisers’ impact on total soil P content and on the P content and P accumulation in wheat grain and straw, weeds and post-harvest residues. Recycled fertilisers maintained soil P stocks and supplied plants with P in the same way as traditional fertilisers, and ensured a comparable P pool in the post-harvest residues to traditional fertilisers. They also did not favour weeds during competitive crop-weed interactions. The PSM included in waste-fertilisers did not exert an evident effect on the soil P content or on the P content and P accumulation in plant biomass. The findings show the potential of recycled fertilisers to act as a substitute to fertilisers from primary sources. Further field research is needed to settle the question of the reasonability of PSM inclusion into fertilisers.

“…In a previous study, which the wheat plants treated with 13.70 mg/kg Cd (a much higher dose than that used in our study, the wheat grain Cd concentration was found to be positively correlated with the root Cd concentration, and Cd redistribution from shoots to grain (Shi et al, 2015). In our study, correlation analyses indicated that the grain Cd concentration was positively correlated with the Cd concentration in each tissue (Table 4), and with the TFs of roots to grain, flag leaves, internode 1 and rachis (Table 4), but not with the RFs (Table 4) roots, and the ability of Cd translocation from roots to the shoots.…”

“…Of the 46 cultivars, 31 had significantly higher grain Cd concentrations in Wenjiang than in Shifang, which might because of the higher Cd concentration in soil of Wenjiang than Shifang roots to older leaves, roots to flag leaves, roots to lower stems, roots to internode 1, or roots to rachis (Table 4). Thus, grain Cd accumulation in these cultivars did not result from Cd translocation from roots to shoot parts (Shi et al, 2015). However, the grain Cd concentration was correlated with the Cd concentrations in the glumes and rachis (Table 4), the TF of roots to grain (Table 4), and all the RFs (Table 4) at the mature stage under low-Cd stress.…”

Background To study the cadmium (Cd) accumulation in wheat grain, we evaluated the grain Cd concentrations of 46 common wheat cultivars grown at two sites in Sichuan, China and selected five different grain Cd accumulators (a high-Cd accumulator ZM18, four low-Cd accumulators YM51, YM53, SM969 and CM104) to explore the physiological processes of Cd accumulation in the grain of wheat grown under varying degrees of Cd stress. Results Our results showed that the Cd concentration in grain differed among genotypes. Under low-Cd stress, the grain Cd concentration was correlated with the Cd translocation factor (TF) of roots to grain and all the Cd redistribution factors (RFs). Compared with the ZM18, the cultivars YM53 and SM969 accumulated less Cd in the grain due to low Cd redistribution from lower stems and older leaves to grain. The low-Cd accumulators YM51 and CM104 were due to low Cd transport from roots to grain, and low Cd redistribution from glumes, flag leaves, lower stems, and older leaves to grain. Under high-Cd stress, the ZM18, YM53, and SM969 accumulated significantly more Cd in the grain, root and other tissues than did YM51 and CM104. Correlation analyses showed that the grain Cd concentration of wheat under high Cd stress was positively correlated with the Cd concentration in each tissue and the TFs of roots to grains, rachis, internode 1 and flag leaves. Conclusions Cd translocation directly from roots to grain and Cd redistribution from shoots to grain determines the Cd accumulation in grain of wheat cultivars under low-Cd stress. Cd uptake by root and then synchronously transported to new shoots determined the differences of Cd accumulation in the grain of wheat cultivars under high Cd stress.

“…For example Yu et al (2006) reported high variation of Cd accumulation in rice grains (0.30-2.19 mg kg À1 ) among 43 cultivars when grown on Cd contaminated soil. Shi et al (2015) also showed variation in Cd concentration (0.14-0.22 mg kg À1 ) in rice grains among 12 cultivars. Therefore, in addition to crop type, cultivar and species type must be considered in risk assessment studies and in setting food consumption guidelines.…”

This review summarizes the findings of the most recent studies, published from 2000 to 2016, which focus on the biogeochemical behavior of Cd in soil-plant systems and its impact on the ecosystem. For animals and people not subjected to a Cd-contaminated environment, consumption of Cd contaminated food (vegetables, cereals, pulses and legumes) is the main source of Cd exposure. As Cd does not have any known biological function, and can further cause serious deleterious effects both in plants and mammalian consumers, cycling of Cd within the soil-plant system is of high global relevance.The main source of Cd in soil is that which originates as emissions from various industrial processes. Within soil, Cd occurs in various chemical forms which differ greatly with respect to their lability and phytoavailability. Cadmium has a high phytoaccumulation index because of its low adsorption coefficient and high soil-plant mobility and thereby may enter the food chain. Plant uptake of Cd is believed to occur mainly via roots by specific and non-specific transporters of essential nutrients, as no Cd-specific transporter has yet been identified. Within plants, Cd causes phytotoxicity by decreasing nutrient uptake, inhibiting photosynthesis, plant growth and respiration, inducing lipid peroxidation and altering the antioxidant system and functioning of membranes. Plants tackle Cd toxicity via different defense strategies such as decreased Cd uptake or sequestration into vacuoles. In addition, various antioxidants combat Cd-induced overproduction of ROS. Other mechanisms involve the induction of phytochelatins, glutathione and salicylic acid.
