Resumo: Castor bean fruits are already used for biodiesel production but obtaining quality seeds is still a challenge. Seed cleaning improves lot quality but little is known about the effects of upgrading castor bean seed lots on a densimetric table. The objective of this study was to evaluate the influence of cleaning castor bean seed lots on a densimetric table on their physical, physiological and sanitary characteristics. Two commercial lots of the AL Guarani 2002 cultivar, separated into five categories according to their classification on a densimetric table (uncleaned and low, low intermediate, high intermediate and high outlets), were evaluated. Tests for the yield, one-thousand seed weight, germination, seedling emergence, electrical conductivity and seed health were performed. The classification of castor bean seeds on a densimetric table significantly improved the physical, physiological and sanitary quality of commercial seed lots. The physiological response of the different classified lots varied according to their initial weight. Castor bean seeds separated on a densimetric table for the upper outlet showed a better physical, physiological and sanitary quality compared to those for the lower outlet.

O beneficiamento de sementes é uma etapa da produção que visa aprimorar a qualidade do lote, no entanto, pouco se conhece sobre os efeitos do aprimoramento de lotes de sementes de mamona em mesa densimétrica. O trabalho foi realizado com objetivo de avaliar a influência do beneficiamento de lotes de sementes de mamona em mesa densimétrica nos seus atributos físicos, fisiológicos e sanitários. Foram utilizados dois lotes comerciais da cultivar AL Guarany 2002 estratificados em cinco categorias de acordo com sua classificação em mesa densimétrica (alimentação e descargas inferior, inferior intermediária, superior intermediária e superior). Avaliaram-se: rendimento, peso de mil sementes, germinação, emergência de plântulas, condutividade elétrica e teste de sanidade. A classificação de sementes de mamona em mesa densimétrica melhora a qualidade física, fisiológica e sanitária de lotes comerciais. A resposta fisiológica dos diferentes lotes de sementes de mamona à classificação varia em função de sua densidade inicial. As sementes de mamona classificadas em mesa densimétrica na descarga superior apresentam melhor qualidade física, fisiológica e sanitária em relação àquelas provenientes da descarga inferior.Associação Brasileira de Tecnologia de Sementes2019-11-28T17:31:27Z2019-11-28T17:31:27Z2012info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSANTOS NETO, A.
