INTERFERÊNCIA DE DOSES DE COBRE NO CRESCIMENTO E NA QUALIDADE DE MUDAS DE <i>Bauhinia forficata </i>Link, <i>Pterogyne nitens </i>Tul E <i>Enterolobium contortisiliquum</i> Vell.

Abstract: RESUMOO cobre é um elemento essencial às plantas, mas quando presente em altas concentrações no solo pode se tornar tóxico ao metabolismo vegetal. Uma das estratégias para reabilitação de áreas contaminadas por metais é a fitorremediação, que consiste na introdução de espécies vegetais no solo contaminado. O trabalho objetivou avaliar a interferência de doses crescentes de cobre aplicadas ao solo no crescimento e na qualidade de mudas de Bauhinia forficata Link, Pterogyne nitens Tul e Enterolobium contortisili… Show more

“…Increased Cu doses in the soil in species of the Fabaceae family induced a linear reduction in the surface area of the roots of Bauhinia forficata Link and Pterogyne nitens Tul seedlings and a quadratic increase in Enterolobium contortisiliquum Vell. up to a dose of 81 mg kg -1 (Silva et al, 2016). The increase in the surface area of absorption of the roots represents an increase in the volume of exploited soil, and according to Harley (1969), the surface area exploited by ectomycorrhizal fungi is estimated to be 1,000 times greater than that of roots without the presence of ectomycorrhiza.…”

“…In a study with copper doses in the Brazilian orchid tree pata-de-vaca (Bauhinia forficata) and carne-de-vaca (Pterogyne nitens) seedlings, Silva et al (2016) found that the shoot dry mass reduction with increasing pollutant levels was significant in both native forest species, with a reduction of 72 and 74% at the maximum dose of 300 mg kg -1 , respectively.…”
