Resumo: Copper (Cu) is a micronutrient necessary for plant development, as it is included in the structure of enzymatic compounds and activators. However, at high soil concentrations it can become toxic to plant metabolism. Thus, the objective of this work was to evaluate the growth and tolerance of Ilex paraguariensis seedlings grown in copper contaminated soil. The study was conducted in a greenhouse of the Department of Forestry Engineering, Federal University of Santa Maria, Campus Frederico Westphalen, RS, between March and September 2018. The seedlings of Ilex paraguariensis used in the experiment were acquired from a nursery located in the municipality of Arvorezinha, RS. The treatments applied were five doses of Cu (0 - control, without addition of copper; 100; 200; 300 and 400 mg Kg-1 of soil). The experiment was carried out in a completely randomized design with 10 replications, each repetition being one plant per pot. After exposure to different treatments under soil cultivation at 150 days, plant height, stem diameter, leaf area, root, stem and leaf dry mass and tolerance index were evaluated. The results showed that the copper doses reduced the seedlings height and stem diameter. The dry mass of all collected partitions showed reduction from the use of 200 mg kg-1 of soil. The plants submitted to higher Cu (400 mg kg-1 soil) showed a reduction in leaf area of 64.7% in relation to the control. The species Ilex paraguariensis presented a tolerance index higher than 60% up to 300 mg kg-1 Cu.

Contudo, em altas concentrações no solo pode se tornar tóxico ao metabolismo vegetal. Dessa forma, o objetivo deste trabalho foi avaliar o crescimento e tolerância de mudas de Ilex paraguariensis cultivadas em solo contaminado com cobre. O estudo foi conduzido em casa de vegetação do Departamento de Engenharia Florestal, Universidade Federal de Santa Maria, Campus de Frederico Westphalen, RS, entre os meses de março e setembro de 2018. As mudas de Ilex paraguariensis utilizadas no experimento foram adquiridas de um viveiro localizado no município de Arvorezinha, RS. Os tratamentos aplicados foram cinco doses de Cu (0 - controle, sem adição de cobre; 100; 200; 300 e 400 mg Kg-1 de solo). O experimento foi implantado em delineamento inteiramente casualizado com 10 repetições, sendo cada repetição uma planta por vaso. Após a exposição aos diferentes tratamentos, sob cultivo em solo aos 150 dias, avaliou-se a altura de planta, diâmetro do caule, área foliar, massa seca de raiz, caule e folhas e índice de tolerância. Os resultados evidenciaram que as doses de cobre reduziram a altura e diâmetro de caule das mudas. A massa seca de todas as partições coletadas mostrou redução a partir da utilização de 200 mg kg-1 de solo. As plantas submetidas a maior dose de Cu (400 mg kg-1 de solo) apresentaram redução na área foliar de 64,7% em relação à testemunha. A espécie Ilex paraguariensis apresentou o índice de tolerância superior a 60% até a dose de 300 mg kg-1 de Cu.Universidade Federal de Santa Maria2022-11-23info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6421610.5902/1980509864216Ciência Florestal; Vol. 32 No. 4 (2022); 1948-1963Ciência Florestal; v. 32 n. 4 (2022); 1948-19631980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/64216/49465https://periodicos.ufsm.br/cienciaflorestal/article/view/64216/52400Copyright (c) 2022 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessLunkes, Antônio Marcos Zuliani Mantovani, Nilton CesarSoriani, Hilda HildebrandRangel Junior, Fabio Santos2023-04-14T13:39:50Zoai:ojs.pkp.sfu.ca:article/64216Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-04-14T13:39:50Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
