Resumo: | The aim of this study was to evaluate the rooting potential of lignified cuttings from 20 native forest species. Two different experiments were conducted and in both cases stem cuttings were about 15 to 20 cm in length. In the first experiment, cuttings from nine species were selected in four diameter classes, 5.0 mm, 9.0 mm, 14.5 mm and 24 mm on average. In the second experiment, cuttings from twenty species were treated with indolebutyric acid (AIB). Each treatment was replicated four times, with 10 randomly arranged cuttings per plot. In both experiments, propagules were placed in seedling tubes containing vermiculite and scorched rice husk at a 1:1 ratio (v:v). They were kept in a greenhouse for 45 days, after this measurements were taken of rooting percentage, number of roots and length of roots per cutting. In the first experiment, six cuttings rooted and rooting rates ranged from 2% to 88%. Best rooting and root system quality results were provided by cuttings 14.5mm in average diameter. As for the second experiment, nine species rooted and rooting percentage ranged from 0.5% to 88%, there being no significant influence of the treatment using AIB. |

Neste estudo, objetivou-se estudar o potencial de enraizamento de estacas lenhosas de 20 espécies florestais nativas. Dois experimentos distintos foram conduzidos. Em ambos, as estacas caulinares apresentavam em média de 15 a 20 cm de comprimento. No primeiro, estacas de nove espécies foram selecionadas em quatro classes de diâmetro, com média de 5,0; 9,0; 14,5 e 24 mm. No segundo, estacas de 20 espécies foram tratadas com ácido indolbutirico (AIB). Cada tratamento foi avaliado em quatro repetições com 10 estacas por parcela arranjadas aleatoriamente. Nos dois ensaios, os propágulos foram estaqueados em tubetes preenchidos com vermiculita e casca de arroz carbonizada na relação 1:1 (v:v). Após 45 dias em casa de vegetação, as porcentagens de enraizamento, número e comprimento de raízes por estaca foram computados. No primeiro experimento, seis apresentaram taxas de enraizamento que variaram de 2 a 88%. Estacas com diâmetro médio de 14,5mm apresentaram melhores resultados em relação ao enraizamento e a qualidade do sistema radicular. Já no segundo, nove espécies enraizaram e o percentual variou de 0,5 a 88%, sendo que não foi verificada influência significativa do tratamento com AIB.Universidade Federal de Lavras (UFLA)2015-05-112017-08-01T20:13:43Z2017-08-01T20:13:43Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfSANTOS, J. de P. dos et al.
