- Abstract:
- Here we report results relative to the concentration, in rice grains from 26 different genotypes, of eight elements with an ascertained (As, Pb, Cd) or potential (Cu, Mn, Mo, Ni and Se) toxicity towards humans. All rice genotypes have been cultivated in the same site and irrigated with the same water using three different irrigation methods: continuous flooding, (CF), sprinkler irrigation (SP) and soil saturation (SA). The PCA analysis of results obtained demonstrate that the average amounts of almost all the elements considered - with the only exception of Ni - are minimized in rice irrigated with SP.
