Description
Summary:To obtain high quality seeds, required efficient and accurate control of all stages of production are required, from selecting seeds in the plant itself and processing. The objective of this study was to evaluate the influence of the order of racemes in fruit harvest and processing in three systems of quality of castor beans. The castor bean seeds were from the production field BRS 149 Nordestina, installed at the Experimental Station of Embrapa Algodão from Barbalha-CE. A completely randomized delineation was used, with a 3 x 3 factorial with four replications, where the factors were: harvest in three orders of racemes (primary, secondary, and tertiary harvested racemes) and three systems of processing (manual, manual machine, and mechanical machine peeling). The seeds from each treatment were subjected to germination tests, vigor, purity analysis, water content, and oil content. The secondary and tertiary racemes produce seeds with high physiological quality in relation to primary. The seeds peeled by a mechanical peeler machine provided greater seedling length, while the seeds processed manually had higher oil content. = Para a obtenção de sementes de alta qualidade, é necessário o controle eficiente e rigoroso de todas as etapas de produção, desde a escolha das sementes na própria planta e beneficiamento. Objetivou-se com este trabalho avaliar a influência da ordem dos racemos na colheita dos frutos e de três sistemas de beneficiamento na qualidade das sementes de mamona. As sementes de mamoneira foram provenientes do campo de produção da cultivar BRS 149 Nordestina, instalado na Estação Experimental da Embrapa Algodão de Barbalha-CE. Foi adotado o delineamento inteiramente casualizado, usando-se o esquema fatorial de 3 x 3, com quatro repetições, onde os fatores foram: colheita em três ordens de racemos (frutos colhidos dos racemos primários, secundários e terciários) e três sistemas de beneficiamento (manual, máquina descascadora manual e máquina descascadora mecânica). As sementes de cada tratamento foram submetidas aos testes de germinação, vigor, análise de pureza, teor de água e teor de óleo. Os racemos secundários e terciários produzem sementes com melhor qualidade fisiológica em relação aos primários. As sementes descascadas em máquina descascadora mecânica proporcionaram maior comprimento das plântulas, enquanto as sementes beneficiadas manualmente apresentaram maior teor de óleo.
