Název v původním jazyce

Trace elements distribution and species fractionation in Brassica napus plant

Popis výsledku v původním jazyce

Trace elements status in parts of the rape (roots, shoots, seeds) was investigated. Roots are able to accumulate large amounts of metals: approx. 2000 mg/kg Fe; 120 mg/kg Mn; 30 mg/kg Zn; 2-8 mg/kg As, Cr, Ni, Cu and Pb; 0.3-1 mg/kg Co, Mo and Cd and 0.1mg/kg Ag and Tl (on dry weight basis). However, the transfer of metals into shoots is limited. The ratios of element contents in shoots and roots are: 10-30% for Ag, Co, Cr, Fe, Mn, Ni and Pb; 50-100% for As, Cd, Cu and Zn; >110% for Tl and Mo. The transfer of elements into the seeds is even lower except for Cu, Zn, Mo and Tl. The ratios of elements contents in seeds and roots are: <20% for Ag, As, Cd, Co, Cr, Fe and Pb; 20-60% for Cu, Mn and Ni; 90% for Tl; 180-190 % for Mo and Zn. The soluble portionof Fe, As and Pb compounds in Tris-HCl buffer (pH=7.5) was <10% of total content, whereas that of other elements was 10-60%. Extracts of all three parts of plant were submitted to SEC/ICP-MS analysis. While the majority of Co, Cu, Mo, Mn
