“…Nevertheless, cadmium exposure led to a decrease in wheat fresh mass accumulation but less compared with the low temperature ( Table 1). The negative effect of Cd on growth have also been reported by Talanova et al (2000), Farooq et al (2013), Li et al (2013), and Han et al (2014). Interestingly, an induced cold tolerance in wheat was also detected after Cd exposure but less than that induced by low temperature.…”

“…Total green and dry mass of the seedlings also had a significant decrease in mean rates (Table 2) , with significant reduction in germination percentage. (HOSSEINI et al, 2012;BAUTISTA et al, 2013); soybean (Glycine max) with 5 mg L -1 cadmium reducing 8% germination (LI et al, 2013); chard (Beta vulgaris) and lettuce (Lactuca sativa), with 18.0 and 19.0% reduction in germination when exposed respectively to 5.2 mg L -1 cadmium (BAUTISTA et al, 2013) and seablite (Suaeda salsa), with a 18.0% decrease when exposed to 6.0 mg L -1 cadmium (LIU et al, 2012).…”

ABSTRACT. Cadmium toxicity in seed germination and seedling growth of wheat (Triticum aestivum, is assessed. The ecotoxicological effects of six experimental concentrations of cadmium (0.03; 0.06; 0.12; 0.6; 1.2; 2.4; 4.8 mM), and control were evaluated. All assays were performed in quadruplicates with 25 seeds per replication in Petri dishes. Responses for toxic effect comprised the variables germination percentage, index of velocity of germination (IVG), length of aerial section and root of the seedlings, green and dry mass of the seedlings. Results showed that T. aestivum seeds exposed to cadmium decreased their normal germination percentage as from 0.03 mM concentration, with a 31% reduction of germination percentage and a 20% decrease in IVG. Cadmium´s inhibition effect on initial growth of seedlings influenced growth of roots and aerial part as from concentration 0.12 mM and reduced the production of green and dry mass of seedlings as from 0.06 mM. The presence and accumulation of cadmium in the soil cultivated with T. aestivum may trigger liabilities in productivity and/or viability caused by its toxicity as from 0.03mM concentrations absorbed by the plant roots.Keywords: ecotoxicology, metal, contamination.Toxicidade do cádmio na germinação de sementes e no crescimento de Triticum aestivum RESUMO. Esta pesquisa avaliou os efeitos tóxicos do cádmio na germinação e crescimento inicial do trigo (Triticum aestivum, var. IAC-370). Foram avaliados os efeitos ecotoxicológicos de seis concentrações de cádmio (0,03; 0,06; 0,12; 0,6; 1,2; 2,4; 4.8 mM). Os experimentos foram em quadruplicatas, com 25 sementes por replicata, em placas de Petri. As variáveis respostas foram o percentual de germinação, o índice de velocidade de germinação (IVG), o comprimento da parte aérea e da raiz das plântulas, a massa fresca e seca das plântulas. Os resultados reportaram que as sementes de T. aestivum expostas ao cádmio apresentaram decréscimo do seu percentual germinativo de plântulas normais a partir a concentração de 0,03 mM, com redução de 31% do percentual germinativo e decréscimo de 20% no IVG. O efeito inibitório do cádmio no crescimento inicial das plântulas afetou o crescimento das raízes e da parte aérea a partir da concentração 0,12 mM, causando a redução da produção de massa fresca e seca das plântulas a partir de 0,06 mM. A presença e acumulação do cádmio, no solo de cultivo da T. aestivum, poderá causar perdas de produtividades e/ou viabilidade provocadas pela sua toxicidade a partir de concentrações de 0,03 mM que estejam absorvidos pela raiz da planta.Palavras-chave: ecotoxicologia, metal, contaminação.

“…No effects of HC on seedling and density of barley were observed. Li et al (2013) and Han et al (2016) found that the germination responses of a number of plants to HC varied greatly depending on the type of plant. A considerable effects of crude oil on the barley physiology were detected.…”

Land treatment of crude oil is used by the oil industry, since it has been recognized that hydrocarbons (HC) can be metabolized by the indigenous microbial community of soil. The crude oil biodegradation in agricultural soil was studied for 12-mo to determine the HC biodegradation and leaching, the effect of HC on barley productivity and soil properties, and the potential for HC uptake in the plant. Concentration and composition of HC in the soil were periodically determined at a depth of 0 to 75 cm. The HC concentration decreased over time due mainly to the microbial degradation. At the end, 12% of the primary crude oil amount remained constant in the soil. A vertical migration, leaching and metabolic products of HC into subsoil occurred. The HC have changed soil fertility. Barley has been successfully cultivated in soil but the HC reduced some plant growth parameters. However, HC were not detected in plant seeds. Many of oil-utilizing bacteria and fungi were isolated from soil. The HC biodegradation potential of oil polluted soil (6% to 66%) were higher than of unpolluted one (4% to 53%). The bacteria (22% to 66%) were more active than fungi (4% to 46%) in HC biodegradation. The study demonstrated that agricultural lands with low rates of oil contamination allows the growth of plants. They ensure high efficiency of HC biodegradation. Vertical infiltration plays an important role in HC removing from soil. Alkanes were completely assimilated by microorganisms and polar compounds were more resistant to microbial attack.
