Summary: | This study was carried out from April to September of 1989, in the experimental field of UFLA, Lavras, MG, Brazil, with the objective of evaluating the influence of concentrations and periods of immersion of paclobutrazol on secondary growth control and marketable traits in garlic (Allium sativum L.). The experimental design was a randomized complete block in a 4 x 5 factorial scheme, with four replications. The first factor consisted of paclobutrazol concentrations (0, 500, 1,000 and 1,500 mg L-1 of a.i.), and the second one of periods of immersion (30, 60, 90, 120 and 150 minutes). Reduction in plant height and in number of leaves per plant from 60 to 90 days after planting with paclobutrazol applications was observed. Mean bulb weight increased up to the concentration of 976 mg L-1 of paclobutrazol, and 451 mg L-1 gave the greatest percentage of bulbs of large size. There was no significant difference among treatments for total and commercial yields, percentage of secondary growth bulbs and number of cloves per bulb. |

Utilizou-se o delineamento experimental de blocos ao acaso em esquema fatorial 4 x 5, compreendendo quatro doses de paclobutrazol (0, 500, 1.000 e 1.500 mg L-1 de i.a.) e cinco períodos de imersão (30, 60, 90, 120 e 150 minutos) e quatro repetições. Observou-se, com o incremento das concentrações de paclobutrazol, uma redução na altura e no número de folhas por planta aos 60 e 90 dias após o plantio. A concentração de 976 mg L-1 de paclobutrazol proporcionou o maior peso médio de bulbo, e a dose de 451 mg L-1 foi a que promoveu a maior porcentagem de bulbos graúdos. Quanto a produtividade total e comercial, porcentagem de bulbos pseudoperfilhados e número de bulbilhos por bulbo, não se verificaram diferenças significativas entre os tratamentos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirade Resende, Geraldo MilanezCosta, Nivaldo Duartede Melo, Natoniel Franklinde Souza, Rovilson José1999-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5203Pesquisa Agropecuaria Brasileira; v.34, n.4, abr. 1999; 635-639Pesquisa Agropecuária Brasileira; v.34, n.4, abr. 1999; 635-6391678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5203/2395info:eu-repo/semantics/openAccess2010-07-05T14:21:42Zoai:ojs.seer.sct.embrapa.br:article/5203Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-05T14:21:42Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
