Availability and toxicity of cadmium to forage grasses grown in contaminated soil

Abstract: It is important to know the mechanisms for forage development, especially those related to the tolerance of potentially toxic elements, when considering their use in phytoremediation in heavy metal contaminated areas. In this study, we evaluated plant growth, concentration, and the availability of cadmium (Cd) for forage grasses (Panicum maximum Jacq. cv. Aruana and cv. Tanzânia; Brachiaria decumbens cv. Basilisk; Brachiaria brizantha cv. Xaraés and cv. Marandu) cultivated in Cd contaminated soils. The experim… Show more

“…Cadmium concentrations in grass shoots increased linearly as Cd rates increased in the three soils (p < 0.01) (Figure 3), confirming the results found by [15,22]. Cd concentrations in shoots are higher in plants grown under higher Cd availability [4,7], where Megathyrsus maximus presented the highest Cd concentration in shoots when cultivated in TQ, and Urochloa brizantha when cultivated in Xantic Hapludox (XH) and RH ( Figure 3).…”

“…Hyperaccumulator plants are those capable of extracting and accumulating the Cd concentration in tissue at values greater than 100 mg kg −1 dry mass [4,19]. Grasses have high potential for phytoremediation purposes due to desirable phytoextraction characteristics such as high-growth rate, biomass production, root growth and capacity to tolerate and accumulate toxic metal [15,19,21,22] with high phytolith production capacity [23][24][25][26].…”

“…Nos anos recentes, o capim tanzânia tem sido estudado sob condições de fitotoxicidade e em recuperação de áreas contaminadas por metais pesados (Miranda et al 2012;Monteiro et al 2011;Nascimento et al 2014;Silva et al 2016). A contaminação dos solos por metais pesados é importante problema ambiental devido aos danos causados na qualidade do solo e as graves consequências na saúde animal e humana.…”

“…Na fitoextração, o contaminante é absorvido pelas raízes e transportado para a parte aérea, tornando possível sua remoção do solo por meio do corte e retirada do material colhido . O capim tanzânia apresenta potencial para ser empregado nessas duas técnicas (Monteiro et al 2011;Nascimento et al 2014;Silva et al 2016;Souza Júnior et al 2018).…”
