Description
Summary:The influence of different concentrations of heavy metals (Cu, Mn, Ni, Zn) was analyzed in the <i>Salsola vermiculata</i> germination pattern, seedling development, and accumulation in seedlings. The responses to different metals were dissimilar. Germination was only significantly reduced at Cu and Zn 4000 μM but Zn induced radicle growth at lower concentrations. Without damage, the species acted as a good accumulator and tolerant for Mn, Ni, and Cu. In seedlings, accumulation increased following two patterns: Mn and Ni, induced an arithmetic increase in content in tissue, to the point where the content reached a maximum; with Cu and Ni, the pattern was linear, in which the accumulation in tissue was directly related to the metal concentration in the medium. Compared to other <i>Chenopodiaceae</i> halophyte species, <i>S. vermiculata</i> seems to be more tolerant of metals and is proposed for the phytoremediation of soils contaminated by heavy metals.
