Resumo: The aim of this work was to observe the interaction between soil moisture and irrigation time intervals on the germination of sugarcane cv. RB785148 sets in semi-controlled conditions. One-bud sets of the variety RB785148 were germinated in ceramic pots filled with soil under a transparent PVC cover using soil humidity levels of 22, 25 and 30%, that were restored at intervals of 7, 14 and 21 days. The experiment was carried out at three different periods of the year: May-June/94; Oct.-Nov./94; and Mar.-Apr./95. The results indicate that the germination decreased mainly in function of the decrease in soil humidity, whereas irrigation interval have no statistical effect on germination. An interaction between humidity level and irrigation interval was observed. A variation of the timecourse of the germination could be observed when the results of the experiments installed at different dates were compared.

RB785148. Toletes de uma gema da variedade RB785148 foram plantados em solo contido em vasos cerâmicos mantidos sob uma cobertura transparente de PVC. Foram utilizados os níveis de umidade do solo de 22, 25 e 30%, restabelecidos em intervalos de 7, 14 e 21 dias. O experimento foi montado em três diferentes épocas do ano: maio-jun./94; out.-nov./94, e mar.-abr./95. Os resultados mostram que houve um decréscimo da germinabilidade em decorrência do teor de água no solo, e observou-se também uma interação entre umidade e o intervalo de irrigação. O fator intervalo não apresentou, isoladamente, efeito significativo sobre a germinação. Observou-se que as curvas de germinação apresentaram diferenças, dependendo da época em que o experimento foi realizado.DRN UFSCar Campus de Araras, CEP 13600-000 Araras, SPDep. de Botânica IB UNESP, CEP 13506-900 Rio Claro, SPDep. de Botânica IB UNESP, CEP 13506-900 Rio Claro, SPUniversidade Federal de São Carlos (UFSCar)Universidade Estadual Paulista (Unesp)Moreira, Divino RodriguesCardoso, Victor José Mendes [UNESP]2014-05-27T11:19:34Z2014-05-27T11:19:34Z1998-05-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article721-729application/pdfhttp://seer.sct.embrapa.br/index.php/pab/article/view/4892Pesquisa Agropecuaria Brasileira, v. 33, n. 5, p. 721-729, 1998.0100-204Xhttp://hdl.handle.net/11449/654422-s2.0-33429399632-s2.0-3342939963.pdf6960838311041673Scopusreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengPesquisa Agropecuária Brasileira0.546info:eu-repo/semantics/openAccess2024-01-05T06:23:06Zoai:repositorio.unesp.br:11449/65442Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462024-08-05T22:10:02.396289Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
