Resumen

RETAMAL-SALGADO, Jorge; MATUS, Ivan; WALTER, Ingrid  y  HIRZEL, Juan. Absorption and distribution of cadmium of three maize hybrids in three environments. J. Soil Sci. Plant Nutr. [online]. 2017, vol.17, n.2, pp.266-278. ISSN 0718-9516.  http://dx.doi.org/10.4067/S0718-95162017005000021.

Anthropogenic soil contamination with heavy metals has received much attention in recent years, especially cadmium (Cd), which is a very toxic element for human health and is exposure is mainly through contaminated food. Maize (Zea mays L.) is one of the most important cereals in the human diet that is characterized as species whose cultivars differ in Cd accumulation. Therefore, identifying and selecting low Cd-accumulating genetic material will contribute to reducing its ingestion. Among the agricultural crops that are important for Cd in the human diet is maize. Cadmium contents in three maize cultivars were grown under different environments conditions in Chile where soils were enriched with increasing Cd rates, were evaluated. Grain yield, Cd concentration in different plant tissues, and soil post-harvest, were evaluated. Results showed that grain yield was not affected by soil Cd; however, plant tissues generally exhibited differences in Cd concentration associated with the environment, La Serena showed the highest grain Cd accumulation (30 µg kg-1; P < 0.05). In addition, among cultivars, Pioneer showed the highest grain Cd concentration (19.5 µg kg-1; P < 0.05).. Grain Cd concentration of the three maize cultivars were within the range cited in the bibliography as not toxic.
