Potensi Pertumbuhan Semai Acacia mangium Willd. pada Tanah yang Terkontaminasi Logam Berat
Abstract: Potency of growth in
Acacia mangium Willd. seedling in the heavy metal contami-nated soil was
studied from July to November 2009. This study aimed to under-stand the growth
of Acacia mangium seedling in the heavy metal contaminated soiland accumulation
of heavy metal in the leaves. The seed was germinated and thenwas planted with
soil from landfill and sandy soil. Student t test was performed tofind the
effect of media to growth of A. mangium. The content of Fe, Zn, Cu, Crand Pb
within the landfill soil before Acacia mangium was planted were higherthan in
sandy soil. For the plants growth in the heavy metal contaminated soil
phyl-lode was fully appear on the 10th leaf, while in the sandy soil it was
fully appear onthe 12th leaf. The highest heavy metal accumulation in root was
Fe, followed b yCu, Zn, Pb, and Cr. Concentration of Fe, Zn, Pb and Cu except
Cr, within the soilreduced after planted with A. mangium.
