“…The increase in leaf area of eophylls in contaminated and bioremediated soils, with reduction in thickness, is contrary to what was reported for most plants studied, such as Amaranthus hybridus (Omosun et al 2008), Corchorus olitorius L. (Adenipekun et al (2009) and Mimosa pilulifera (Inckot et al 2008). In general, reduction in leaf area is attributed to water stress caused by the contaminant (Maranho et al 2006;Adenipekun et al 2008Adenipekun et al , 2009). As A. edulis exhibited an increase in leaf area of eophylls and alteration in the size of epidermic cells, it is believed that water stress was minimized by the quick response of the plant, with root branching and formation of root hairs.…”

“…The morpho-anatomical structure of plants can also be affected by hydrocarbons in the soil (Maranho et al 2006;Inckot et al 2008). Some species in petroleum-contaminated soil exhibited reduction in root-cell divisions (Achuba 2006), reduction in the meristematic region (Inckot et al 2008), alterations in the structure of root hairs (Alkio et al 2005), reduction in leaf area, changes in stomatal density (Adenipekun et al 2008), and in the aspect and thickness of the epicuticular wax (Omosun et al 2008), among other alterations.…”

This study aimed to assess the effect of petroleum-contaminated and bioremediated soils on germination, growth and anatomical structure of Allophylus edulis. We tested oil-contaminated soil, bioremediated soil and non-contaminated soil. We evaluated germination percentage, germination speed index (GSI), biomass and length of roots and shoots, total biomass, root and hypocotyl diameter, thickness of eophylls and cotyledons, leaf area, eophyll stomatal index and seedling anatomy. Germination percentage, GSI, biomass and leaf area did not differ between treatments after 30 days. Root biomass and plant height were lower in the noncontaminated treatment. Root biomass and leaf area differed between treatments after 60 days. Thickness of cotyledons was higher in bioremediated soil than in other treatments. Root and eophyll structure showed little variation in contaminated soil. We conclude that A. edulis was not affected by petroleum in contaminated and bioremediated soils and that this species has potential for phytoremediation.

“…Embora a maioria dos trabalhos relate baixo desenvolvimento de plantas em solo contaminado (Racine 1994;Li et al 1997;Adam & Duncan 1999;Gill et al 1992;Dorn & Salanitro 2000;Chupakhina & Maslennikov 2004;Merkl et al 2005;Achuba 2006;White et al 2006;Omosun et al 2008;Farias et al 2009), também há registros de maior comprimento radicial (Baker 1970) e até de recuperação da biomassa (Merkl et al 2005). Alterações estruturais, como maior ramifi cação (Adam & Duncan 1999), alterações no formato das células da raiz (Farias et al 2009), redução das divisões celulares da raiz (Merkl et al 2004;Achuba 2006), alteração da estrutura dos pêlos radiculares (Alkio et al 2005), redução da área foliar, alteração na densidade estomática (Maranho et al 2006;Omosun et al 2008) e modifi cações no aspecto e espessura da cera epicuticular (Baker 1970;Omosun et al 2008) foram registradas em diferentes espécies em solo contaminado.…”

Efeito do solo contaminado com óleo diesel na estrutura da raiz e da folha de plântulas de Sebastiania commersoniana (Euphorbiaceae) e Schinus terebinthifolius (Anacardiaceae) ABSTRACTEff ect of diesel contaminated soil on root and leaf of Sebastiania commersoniana (Euphorbiaceae) and Schinus terebinthifolius (Anacardiaceae)). Th e objective of this study was to evaluate whether the diesel contaminated soil alters the structure of the root and eophyll of S. commersoniana (Euphorbiaceae) and S. terebinthifolius (Anacardiaceae) seedlings. For each species three treatments with contaminated soil were tested, and compared to a control of uncontaminated soil. Th e treatments diff ered by the time between contaminations and sowing. S. commersoniana was sown 60, 120 and 210 days and S. terebinthifolius 30, 90 and 180 days aft er contamination. Samples of root and eophyll were collected 30 days aft er sowing and analyzed qualitatively and quantitatively. Seedlings of S. commersoniana and S. terebinthifolius, grown in diesel contaminated soil, had their root and eophyll anatomy modifi ed. Th e time interval between contamination and sowing interferes with the soil phytotoxicityl. When greater the time interval between contamination and sowing lower were the anatomical changes. Seedlings of S. terebinthifolius seemed more resistant to contamination than those of S. commersoniana.

“…Part of this area is being subjected to a bioremediation process aiming to reduce the TPH (Total Petroleum Hydrocarbon) content in the soil to a non-toxic level. Studies are being conducted to understand the influence of petroleum contamination, as well as the bioremediation process on the flora at this site (Bona and Santos, 2003;Maranho et al, 2006Maranho et al, , 2009Inckot et al, 2008).…”

Germination and initial growth of Campomanesia xanthocarpa O. Berg. (Myrtaceae), in petroleum-contaminated soil and bioremediated soil

et al. 2010

View full text Add to dashboard Cite

In 2000 there was an oil spill at the Getúlio Vargas Refinery (REPAR) in Paraná. Nearly five years after contamination and the use of bioremediation, a study was carried out to identify the effects of the contaminated soil and the bioremediated soil on the germination and initial growth of C. xanthocarpa. The experiment was established with soil from REPAR, with three treatment groups: contaminated soil (C), bioremediated soil (B) and uncontaminated soil (U); with five repetitions of 50 seeds each. There was no significant difference in the percentage of germination and the speed of germination index. The production of total biomass (30 -60 days) and shoot biomass (60 days) was greater in the bioremediated soil compared to the other treatments. The averages for the root biomass were lower in the contaminated soil than in the bioremediated soil. The shoot length and the total length of the seedling in the contaminated soil and uncontaminated soil were lower than in the bioremediated soil.Keywords: biomass, gabiroba, hydrocarbon contamination, seedling growth. Germinação e crescimento inicial de Campomanesia xanthocarpa O. Berg. (Myrtaceae), em solo contaminado com petróleo e solo biorremediado ResumoEm 2000, ocorreu um vazamento de petróleo na área da Refinaria Getúlio Vargas (REPAR), no Paraná. Após cerca de cinco anos da contaminação e utilização do processo de biorremediação, pretendeu-se identificar os efeitos do solo contaminado e do solo biorremediado na germinação e no crescimento inicial de C. xanthocarpa. O experimento foi montado com solo da REPAR, com três tratamentos -solo contaminado (C), solo biorremediado (B), solo não contaminado (U) -e cinco repetições com 50 sementes cada. Não houve diferença significativa na porcentagem e no índice de velocidade de germinação. A produção de biomassa total (30 -60 dias) e biomassa da parte aérea (60 dias) foram maiores no tratamento biorremediado em relação aos demais tratamentos. As médias para a biomassa da raiz foram menores no solo contaminado do que no solo biorremediado. O comprimento da parte aérea e o comprimento total da plântula no solo contaminado e no não contaminado foram menores do que no biorremediado.Palavras-chave: biomassa, gabiroba, contaminação por hidrocarbonetos, crescimento de plântula.
