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.
