Resumo: The objective of this work was to verify the effect of the water deficit, applied in different times and periods without irrigation, in the incidence of the secondary bulb growth and in the yield of noble vernalized garlic, cultivar "Roxo Pérola de Caçador". The experiment was conducted under field conditions, using the experimental design of randomized blocks, with three replications. The factorial scheme used was 4x4+1, with four irrigation suspension times (at the 50, 55, 60 and 65 days after planting), four periods of water deficit (8, 12, 16 and 20 days), and one control treatment, not submitted to water deficit. The bulbs used for planting were submitted to the vernalization of 50 days at 4ºC. The increase in the period of water deficit in all times reduced linearly the secondary bulb growth taxes, with linear increment in the production of commercial bulbs. Larger periods of water deficit favor the obtainment of commercial bulbs with larger medium mass.

O experimento foi conduzido em condições de campo, utilizando-se o delineamento de blocos casualizados, com três repetições. Utilizou-se o esquema fatorial 4x4+1, com quatro épocas de suspensão da irrigação (aos 50, 55, 60 e 65 dias após o plantio), quatro períodos de deficit hídrico (8, 12, 16 e 20 dias), e um tratamento controle, não submetido ao deficit hídrico. Os bulbos-semente foram submetidos à vernalização de 50 dias a 4ºC. O aumento no período de deficit hídrico, em todas as épocas, possibilitou redução linear nas taxas de superbrotamento, permitindo incremento linear na produção de bulbos comerciais. Maiores períodos de deficit hídrico favorecem a obtenção de bulbos comerciais com maior massa média.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMacêdo, Fábio SilvaSouza, Rovilson José dePereira, Geraldo Magela2006-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7184Pesquisa Agropecuaria Brasileira; v.41, n.4, abr. 2006; 629-635Pesquisa Agropecuária Brasileira; v.41, n.4, abr. 2006; 629-6351678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7184/4229info:eu-repo/semantics/openAccess2014-09-26T18:52:02Zoai:ojs.seer.sct.embrapa.br:article/7184Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-26T18:52:02Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
