Resumo: Rhododendron thomsonii (Ericaceae) is a chinese ornamental hardwood species. The seeds are used just for hybrids production, therefore, vegetative propagation is an appropriate way for large scale plant production. The rooting potential was evaluated in cuttings collected in spring/2004 from stock plants localized in Curitiba, Paraná. The stem cuttings were produced with 12 cm long, right cut upper and bevel bellow, with two half leaves and treated with sodium hypochlorite for ten minutes and current water for five minutes. The cuttings basis were dipped in IBA treatments (0, 1000, 2000, 4000mgL-1) in alcoholic solutions and talc (0, 1000, 2000, 4000 mgKg-1), totalling eight treatments with four replications of nine cuttings. Mean separation were made using a pair wise design (4X2) in a association between dosage and application ways. The cuttings were planted in vermiculite medium and maintained in greenhouse for 70 days. The evaluation included percentage of rooting, callus cuttings (without root with callus), alive and dead cuttings. No rooting was verified in cuttings collected in this season. The variance analysis showed no interactions between dosage and application ways.

Com a finalidade de avaliar o enraizamento desta espécie para estacas colhidas na primavera (setembro/2004), foram selecionadas plantas-matrizes adultas situadas no Município de Curitiba – PR. As estacas semilenhosas foram obtidas com comprimento aproximado de 12cm, cortadas em bisel na parte inferior e em corte reto na parte superior, com duas folhas reduzidas à metade. O tratamento fitossanitário foi realizado utilizando-se imersão das estacas em hipoclorito de sódio 0,5% (10 minutos) seguida de lavagem em água corrente (5 minutos). Posteriormente as bases das estacas foram imersas em soluções alcoólicas (50%) com diferentes concentrações de ácido indol butírico (IBA), (0, 1000, 2000 e 4000mgL-1), e em talco (0, 1000, 2000 e 4000mgKg-1), totalizando 8 tratamentos com 4 repetições de 9 estacas por parcela. O delineamento experimental utilizado foi o arranjo fatorial (4X2) entre as dosagens utilizadas e as formas de aplicação. As estacas foram plantadas em tubetes contendo vermiculita de granulometria média e mantidas em casa-de-vegetação climatizada por 70 dias. As avaliações compreenderam porcentagens de estacas enraizadas, com calos (sem raiz e com calos), vivas (sem raízes e sem calos) e mortas. Não houve enraizamento para estacas coletadas nesta época do ano. A análise de variância revelou que os fatores dosagens e formas de aplicação não apresentaram interação. Na comparação de médias para porcentagens de estacas vivas e mortas, os tratamentos não apresentaram diferenças estatisticamente significativas.UEL2006-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/239710.5433/1679-0359.2006v27n1p35Semina: Ciências Agrárias; Vol. 27 No. 1 (2006); 35-42Semina: Ciências Agrárias; v. 27 n. 1 (2006); 35-421679-03591676-546Xreponame:Semina.
