%0 Journal Article %T The possibility of using 5-aminolevulinic acid in lead phytoextraction process %A Zbigniew Jarosz %A Katarzyna Dzida %A Karolina Pitura %A Joanna Konopi¨˝ska %J Modern Phytomorphology %D 2013 %I Modern Phytomorphology %X Studies conducted in the greenhouse involving a sunflower (Helianthus annuus L.) grown in medium containing 200 mg Pb dm -3 which were designed to evaluate the impact of foliar nutrition with 5-aminolevulinic acid (5-ALA) on the chemical composition of sunflower in reference to possible use of this plant in the process of induced phytoextraction. The study revealed from 4.8% to 34.1% increase in aboveground matter of sunflower which was sprayed by 5-ALA solution at concentrations of 0.01-0.1 ppm in comparison with plants grown in a medium containing 200 mg Pb dm -3 with no 5-ALA spraying. The sunflower leaves sprayed by 5-ALA solution contained from 3.78% to 27.1% more lead in comparison to plants not sprayed by this agent. As well as remarkable decrease in lead content from 17.4 to 33.4% was recorded in the roots of sunflower sprayed by 5-ALA solution.
