Resumo: | The work had as objective to do a morphometric characterization of the fruits and seeds, to identify the best treatments to overcome dormancy, identify the best temperature for germination and also evaluate adequate conditions for storing the seeds of Caesalpinia pulcherrima (L.), which is a specie used for live fences, windbreakers, medicinal applications and urban landscaping. It was determined the biometrics measurements (length, width end thickness) and embryo type, weight of 1000 seeds, number of seeds per fruit, color, shape and micropyle and hlium position. It was evaluated the effect of different treatments to dormancy overcome, temperatures of germination and storing conditions. The experimental procedures used were completely randomized with four repetitions of 25 seeds. The fruit of C. pulcherrima is a type of legume, dehiscent, polyspermic, with an average of 7 seeds per unit, which have an oblong-oval format, axial embryo, with 9.6 mm of length, 7.3 mm of width and 3.3 mm of thickness. The mechanical scarification of the seeds on the opposite side of the micropyle and temperature of 30°C provided the best results for germination. The physiological quality of the seeds was maintained for 270 days when the seeds were stored with 7% of moisture content independent of the package and storing conditions. |

Para a caracterização morfométrica, determinouse o comprimento, espessura, largura, massa de 1000 sementes, número de sementes por fruto, coloração, formato e localização do hilo e da micrópila, tipo de embrião, sua localização e tipo de germinação. A qualidade fisiológica das sementes foi avaliada em função de diferentes tratamentos de superação de dormência, temperaturas e condições de armazenamento. Os ensaios foram instalados sob delineamento inteiramente casualizado, com quatro repetições de 25 sementes. O fruto é do tipo legume, deiscente, polispérmico, contendo em média sete sementes, que apresentam formato oblongo-ovalado, embrião axial linear, com 9,6 mm de comprimento, 7,3 mm de largura por 3,3 mm de espessura. A escarificação mecânica das sementes em lado oposto à micrópila e a temperatura de 300C constituíram no melhor tratamento germinativo. A qualidade fisiológica das sementes foi mantida por 270 dias, quando armazenadas com grau de umidade de 7%, independente da embalagem e condições de armazenamento.
