Resumo: The objective of this work was to evaluate the influence of the time between the treatment application to the dormancy break and the artificial rain on the bud burst in young apple (Malus domestica Borkh) trees. The experiment was carried out with potted Gala apple samplings during 1992 and 1993. The treatments included application of the chemicals mineral oil (MO) and hydrogenated cyanamide (HC) for dormancy break, associated or not with an artificial rain of 25 mm applied during 45 minutes. The artificial rain was applied just after the spray with MO plus HC, at 0.5, 1, 2, 4, 8, and 24 hours. In both years, the treatment for breaking the dormancy without rain resulted in the highest (60.7%) effect on bud burst. Among the treatments that received artificial rain, the lowest bud burst was observed when the rain was applied just after the application of the dormancy break treatment. However, there were no significant differences on bud burst among the treatments exposed to the artificial rain from 30 minutes after spraying MO plus HC, which indicates that the chemical treatment does not need to be reapplied under these circumstances.

O experimento foi conduzido em vasos, com macieira da cultivar Gala, de 1992 a 1993. Os tratamentos para quebra de dormência foram realizados com aplicações de óleo mineral (OM) mais cianamida hidrogenada (CH), associado ou não com chuva artificial de 25 mm, durante 45 minutos. A chuva artificial foi aplicada logo após a pulverização de OM + CH, a 30 minutos, 1, 2, 4, 8 e 24 horas. Nos dois anos, os tratamentos sem chuva foram mais eficientes, com 60,7% de brotação de gemas. Entre os tratamentos com chuva artificial, obteve-se uma menor percentagem de brotação de gemas quando as plantas foram expostas à chuva logo após o tratamento de quebra de dormência. No entanto, não se verificam diferenças significativas na brotação entre os tratamentos expostos à chuva artificial a partir de 30 minutos após aplicação de OM + CH, indicando que se ocorrer chuvas após esse período não se torna necessário reaplicar os produtos químicos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPalladini, Luiz AntonioPetri, José Luiz1997-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4708Pesquisa Agropecuaria Brasileira; v.32, n.7, jul. 1997; 715-717Pesquisa Agropecuária Brasileira; v.32, n.7, jul. 1997; 715-7171678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4708/7333info:eu-repo/semantics/openAccess2015-03-03T17:37:59Zoai:ojs.seer.sct.embrapa.br:article/4708Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-03-03T17:37:59Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
