Resumo: Copper contamination has become common in areas of mining and grape culture in Rio Grande do Sul. The aim of this study was to evaluate the influence of the dose of copper on growth and seedling  quality of acoita-cavalo and aroeira-vermelha. The experimental design was completely randomized in a factorial scheme (2 x 5), using two forestry species and five copper doses: 0, 64, 128, 192 and 256 mg kg-1 of soil, with five replications. Plant height, collar diameter, dry mass weight of root system and shoot, length and surface specific area of root system and index of seedlings quality were evaluated and relation between shoot height and haste diameter, shoot height  and  shoot dry mass weight and Dickson quality index were assessed. The results showed that the copper doses tested did not change the quality of aroeira-vermelha seedlings but acoita-cavalo displayed better quality with the application of 64 mg kg-1 Cu. Copper primarily affected the acoita cavalo and aroeira-vermelha root system. Aroeira vermelha was more tolerant to copper toxicity than acoita-cavalo and displayed better quality at higher copper doses.

O trabalho objetivou avaliar o efeito de doses de cobre sobre o crescimento e qualidade de mudas de açoita-cavalo e aroeira-vermelha. O delineamento foi inteiramente casualizado num fatorial (2 x 5), sendo as duas espécies florestais e cinco doses de cobre: 0, 64, 128, 192 e 256 mg kg-1 de solo, com cinco repetições. Avaliaram-se altura da planta, diâmetro do colo, peso da matéria seca radicular e da parte aérea, comprimento e área superficial específica radicular, e os índices de qualidade de mudas: relação entre altura da parte aérea e diâmetro do coleto; altura da parte aérea e peso da matéria seca da parte aérea e o Índice de Qualidade de Dickson. Os resultados revelaram que as doses testadas de cobre não alteraram a qualidade de mudas de aroeira-vermelha, enquanto que o açoita-cavalo apresentou melhor qualidade com aplicação de 64 mg kg-1 de Cu. O cobre afeta primeiramente o sistema radicular das mudas de açoita-cavalo e aroeira-vermelha. A aroeira-vermelha é mais tolerante a elevadas doses de cobre do que o açoita-cavalo.Universidade Federal de Santa Maria2011-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/275310.5902/198050982753Ciência Florestal; Vol. 21 No. 1 (2011); 111-118Ciência Florestal; v. 21 n. 1 (2011); 111-1181980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2753/1679Silva, Rodrigo Ferreira daSaidelles, Fábio Luiz FleigSilva, Alessandro Salles daBolzan, Juan Silveirainfo:eu-repo/semantics/openAccess2017-05-04T16:53:10Zoai:ojs.pkp.sfu.ca:article/2753Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-04T16:53:10Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
