Content of heavy metals in various populations of Tanacetum parthenium grown on chernozem

Abstract

The content of some heavy metals (Pb, Cr, Ni and Cr) was monitored in the leaf, flower head and stem of four Feverfew populations (Tanacetum parthenium) grown in two models of crop establishment (spring and autumn), in South Banat, on chernozem. Concentrations of Ni and Cr in the analyzed plant material were at common level for plant material (bellow 5μg g-1). Concentration of Pb in the most plant organs was bellow MPC, except for one case of increased content (5,9-7,8μg g-1) registered in leaves of population TP10. Variability of Cd concentration (0,2-0,6μg g-1) in different plant organs gives reason to suppose that in Feverfew plants there is an increased potential for accumulation of this heavy metal. Mutual differences between tested populations were observed only in Cd content, while there were no significant differences in the content of Pb, Ni and Cr. Model of crop establishment did not have significant influence on concentrations of tested heavy metals in Feverfew populations.

Istraživan je sadržaj teških metala Pb, Cr, Ni i Cr u listu, cvetu i stablu četiri različite populacije Tanacetum parthenium gajene na černozemu južnog Banata u proljetnom i jesenjem roku zasnivanja. Koncentracije Ni i Cr u analiziranim biljnim organima su bile na uobičajenom nivou za biljni materijal to jest ispod 5μg g-1. Koncentracija Pb takođe je za većinu ispitivanih uzoraka bila ispod MDK, osim pojedinačnog slučaja povećanog sadržaja (5,9-7,8μg g-1) registrovanog u listovima populacije TP 10. Variranje koncentracija Cd u intervalu 0,2 -0,6μg g-1 u različitim biljnim delovima otvara mogućnost za pretpostavku da postoji povećani potencijal usvajanja ovog elementa od strane vrste T. parthenium. Međusobne razlike između testiranih populacija ispoljile su se jedino u sadržaju Cd, dok značajnih razlika u sadržaju Pb, Ni i Cr nije bilo. Rok zasnivanja nije imao značajnog uticaja na koncentraciju teških metala u biljkama povratiča.
