Resumo: The dormancy intensity and chilling requirement of willow (Salix x rubens Shrank) were investigated in excised single node shoots. Observations were made from branches collected in Lages, Santa Catarina State, Brazil, at 21 days interval from March, 29th to August 2and, 2004. Budburst of buds from bottom, middle, and top segments of branches under natural chilled or completed with artificially chill by 500, and 1000 hours at 5±3ºC was evaluated. The sprouted were evaluated at wetting bud, expose bud; steam larded and opened leaf station. The most intensive dormancy occurred on May 10th and it was improved from the basal to top part of the branches. The chill treatment with 500 hours at 5±3ºC was effective in reducing the time to budburst. The real ability of bud development can be assessed only if observations are carried out until appearance of opened leaves.

As observações foram realizadas em ramos coletados em Lages, SC, a intervalos regulares de 21 dias, de 29/03/2004 a 2/08/2004. A brotação de gemas dos segmentos basal, mediano e distal de ramos do ano foi avaliada na ausência ou após suplementação de frio (500 ou de 1000 horas a 5 ± 3ºC). A brotação de gemas foi avaliada nos estádios: a) gemas inchadas; b) início da abertura das gemas; c) broto alongado e; d) broto alongado com folha aberta. A intensidade de dormência das gemas foi crescente da base para a ponta dos ramos e foi máxima em 10 de maio, para todas as regiões do ramo. O tratamento com 500 horas de frio foi efetivo em reduzir o tempo para a brotação, em todas as épocas e posições das gemas no ramo. A avaliação até o aparecimento de folhas abertas foi importante para identificar a real capacidade de brotação das gemas.Universidade Federal de Santa Maria2006-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/192410.5902/198050981924Ciência Florestal; Vol. 16 No. 4 (2006); 427-435Ciência Florestal; v. 16 n. 4 (2006); 427-4351980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1924/1166Rech, Tássio DreschZanette, FlávioBrandes, DieterAmarante, CassandroCabel, Sandra Reginainfo:eu-repo/semantics/openAccess2017-05-15T11:56:03Zoai:ojs.pkp.sfu.ca:article/1924Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-15T11:56:03Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
