Abstract: This work reports the evaluation of sunflower growth under different irrigation conditions and explores a metallomic approach for evaluation of metal and non-metal content in different plant tissues. Sunflowers were cultivated in the presence of zinc (acetate salt) and selenium (as sodium selenite) by adding ca. 230 or 430, and ca. 190 or 350 mg, respectively, during the cultivation period. These plants were compared with controls in terms of some monitored ions ((24)Mg(+), (31)P(16)O(+), (32)S(16)O(+), (56)Fe(+), (64)Zn(+), (80)Se(+)) using ICP-MS. The results highlighted no apparent problem during the development period for those plants cultivated in the presence of zinc. However, higher selenium levels are present mainly in leaves, which can be due to its incorporation in synthesized amino acids such as selenocysteine and selenomethionine. (C) 2010 Elsevier B.V.
