Contudo, há espécies, sob a infl uência do solo contaminado por óleo, que não apresentaram alteração no diâmetro das raízes (Merkl et al 2005;Inckot et al 2008). Outras, no entanto, como Chromolaena odorata (L.) R.M.…”

“…Os efeitos da contaminação variam de acordo com o tipo e a quantidade de óleo, a época do ano, o tipo de solo, a idade e espécie vegetal (Baker 1970;Pezeshki et al 2000;Merkl et al 2005;Kayode et al 2009;Kisic et al 2009). O contaminante pode ser absorvido pelas plantas (Bossert & Bartha 1985;Alkio et al 2005;Tan et al 2005), além de alterar as propriedades do solo (Racine 1994;Li et al 1997;Martinez & López 2001;Roy et al 2003;Chupakhina & Maslennikov 2004;Peña-Castro et al 2006).…”

Solos com hidrocarbonetos têm tendência a reter menor quantidade de água (Roy et al 2003;Peña-Castro et al 2006), a apresentar menor disponibilidade de oxigênio (Pezeshki et al 2000;Merkl et al 2005) e de nutrientes (De Jong 1980). Entre os nutrientes menos disponíveis após contaminação do solo com hidrocarbonetos destaca-se o nitrogênio, um dos mais restritivos ao crescimento das plantas (Marschner 1995).…”

“…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.

“…Petroleum and its derivatives can affect the availability of water, oxygen and nutrients in the soil (Pezeshki et al 2000;Merkl et al 2005;Adenipekun et al 2008). Consequently, these substances can alter seed germination (Adam & Duncan 2002;Ogbo 2009), growth (Adam & Duncan 1999;Merkl et al 2004) and plant biomass production (Malallah et al 1996;Sharifi et al 2007).…”

Phytotoxicity of petroleum-contaminated soil and bioremediated soil on Allophylus edulis

et al. 2011

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.
