Resumo: | This study aimed to assess the effect of harvesting times and of post-harvest resting period on physical characteristics of fruits and seeds of castor bean (AL Guarany 2002 genotype) and to verify if theses characteristics could be used to identify the ideal harvest time. Nine times of raceme harvest were assessed from 30 to the 142 days after anthesis (DAA) at fourteen days intervals, and four conditions of resting; (without and with seven days of resting period of seeds extracted (bare), from fruits and fixed to the racemes). It was evaluated water content, seed thickness, and length, width, and weight of fresh fruits and seeds, and seedling emergence in sand. The statistical design was completely randomized with four replications. The harvest times and the post-harvest rest period affected the physical characteristics of fruits and seeds of castor bean but none of these have proved to be effective in the identification of the ideal harvest time. |

Foram avaliadas nove épocas de colheita dos racemos, no período de 30 até 142 dias após a antese (DAA), em intervalos de 14 dias e quatro condições de repouso: sem e com repouso de sete dias de sementes extraídas (nuas), de frutos e de frutos presos ao racemo. O teor de água e a espessura das sementes, o comprimento, largura e peso fresco dos frutos e sementes e a emergência de plântulas em areia foram avaliados em um delineamento inteiramente casualisado, com quatro repetições. Concluiu-se que os períodos de colheita e de repouso pós-colheita afetaram as características físicas de frutos e sementes de mamoneira, mas nenhuma dessas características foi alterada de forma significativa por ocasião da maior porcentagem de emergência de plântulas, não podendo ser utilizada para a identificação do ponto ideal de colheita.UEL2009-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/463610.5433/1679-0359.2009v30n4Sup1p999Semina: Ciências Agrárias; Vol. 30 No. 4Sup1 (2009); 999-1008Semina: Ciências Agrárias; v. 30 n. 4Sup1 (2009); 999-10081679-03591676-546Xreponame:Semina.
