| RESUMOO acúmulo e a compartimentalização de zinco são distintos entre as espécies florestais. O objetivo do trabalho foi, portanto, avaliar a capacidade de acumulação e de translocação de zinco em mudas de Eucalyptus e Corymbia em solo contaminado com zinco. O experimento foi conduzido no período de outubro de 2011 a março de 2012, em casa de vegetação, em delineamento experimental inteiramente casualizado, com arranjo fatorial (4 x 8), com doze repetições. Foram utilizadas quatro espécies: Eucalyptus. grandis W. Hill ex Maid., Eucalyptus. salignaSmith, Eucalyptus. dunnii Maiden e Corymbia citriodora (Hook.) K.D. Hill & L.A.S. Johnson, e oito doses de zinco (0, 140, 280, 420, 560, 700, 840 e 980 mg kg-1 de solo). As mudas das espécies florestais... |

| ABSTRACTHigh concentrations of copper (Cu) may be toxic to plants, yet some species can be tolerant to soils contaminated by this metal. The study aimed to evaluate Cu translocation and tolerance in seedlings of ‘timbaúva’ (Enterolobium contortisiliquum (Vell.) Morong), ‘pata-de-vaca’ (Bauhinia forficata Link) and ‘amendoim-bravo’ (Pterogyne nitensTul) subjected to Cu-contaminated soil. The study was conducted in a greenhouse for 120 days, using as substrate a clayey Oxisol. The experiment was set in a completely randomized design, using a 3 x 6 factorial scheme, corresponding to three forest species (‘timbaúva’, ‘pata-de-vaca’ and ‘amendoim-bravo’) and six Cu doses in the soil (0, 60, 120, 180, 240 and 300 mg kg-1), with six replicates. The following... |

| ABSTRACT Phytoremediation is a technique that uses plants, whether associated or not to ameliorating agents, for phytostabilization of contaminated soil. The aim of this study was to evaluate the use of Senna multijuga associated with peat in the phytostabilization of copper contaminated soil. The experiment was carried out in a greenhouse for 120 days, using an entirely randomized design in a factorial arrangement (2 x 6), with and without peat (200 mL L-1 soil) and six doses of copper (0, 60, 120, 180, 240, 300 mg kg-1), with six repetitions of each treatment. At 120 days after seedling, the plants were evaluated for height, stem diameter, root and aerial dry matter, contents and accumulated amount of copper in the root system and aerial part. Also, the... |
