Resumo: | Due to the important ecological function of Eremanthus erythropappus (candeia) wood, combined with the growing demand for its products, studies are being made to develop its silviculture. Among these studies, it is important and strategic to start with the cloning process due to the need for improvement of the stand quality that are to be planted. The initial step toward this goal was to define a methodology for rescue of stock plants and rooting of the species cuttings. As a way to rescue the stock plants, 24 trees aged six years of a candeia stand were severed at 15, 30, 45 and 60 cm in height above ground. In 12 trees, it was proceeded soil scarification. The counting and harvesting of sprouts were performed 65 and 135 days after cut, respectively. From the shoots obtained, three types of cuttings were prepared: Top 1, Top 2 and Basal, which were treated with IBA at concentrations of 0, 200, 400, 800 or 1600 mg kg-1 and placed in a greenhouse for rooting. Based on the results, it was conclude that cut, independent of the height, followed by soil scarification and the rooting of cuttings prepared from the shoots collected in the roots, is an effective method for rescue of stock plants and rooting of candeia cuttings and the highest percentage of rooting was found in the Top1 cuttings and did not vary in function of AIB concentration. |

Pelo importante papel ecológico que a espécie Eremanthus erythropappus (candeia) desempenha, aliado à crescente demanda pelos produtos obtidos dessa espécie, trabalhos vêm sendo feitos com o intuito de desenvolver sua silvicultura. Dentre os estudos com a espécie, é necessário iniciar o processo de clonagem, em razão da necessidade de melhorar a qualidade dos povoamentos a serem implantados. Portanto, o passo inicial para esse objetivo foi definir uma metodologia para resgate de matrizes e enraizamento de estacas da espécie. Como forma de resgatar as matrizes, 24 árvores de um povoamento de candeia com seis anos de idade foram decepadas a 15, 30, 45 e 60 cm de altura em relação à superfície do solo, sendo que em 12 árvores, procedeu-se ao tratamento de escarificação do solo. A contagem e a coleta de brotos foram executadas aos 65 e 135 dias após a decepa, respectivamente. Das brotações obtidas, foram confeccionados três tipos de estacas: Apical 1, Apical 2 e Basal, que foram tratadas com AIB nas concentrações de 0, 200, 400, 800 ou 1600 mg kg-1 e colocadas para enraizarem em casa de vegetação climatizada. Com base nos resultados, concluise que a decepa, independente da altura, seguida da escarificação do solo e o enraizamento das estacas preparadas a partir das brotações coletadas de raízes é um método eficiente para resgate de matrizes e enraizamento de estacas de candeia, sendo que os maiores percentuais de enraizamento foram encontrados para as estacas apicais, não variando em função da concentração de AIB.Universidade Federal de Lavras (UFLA)2016-04-052017-08-01T20:13:17Z2017-08-01T20:13:17Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfMELO, L.
