Resumo: | Caesalpinia ferrea Mart. ex. Tul. var. ferrea is a tree of the family Fabaceae that is recommended in the ornamentation of parks, squares, central gardens on avenues, roads and parking lots. Thus, the objective of this study was to evaluate the germination and vigor of their seeds exposed to different light conditions and temperatures. The work was performed at the Laboratory of Seed Analysis, at ‘Centro de Ciências Agrárias’, Center of Rural Sciences, at the Federal University of Paraíba state, in the city of Areia, with seeds of Caesalpinia ferrea submitted to the following treatments: white light, green light, red light, far-red and dark light (no light) regimes, at constant temperatures of 25 and 30°C and 20-30°C, alternating. The characteristics evaluated were: germination, first count and rate of germination and length and seedling dry weight. The germination of the seeds of Caesalpinia ferrea is favored by alternating temperature of 20- 30°C and is not influenced by the regimes of light and the species is neutral photoblastic. |

Tul. var. ferrea é uma arbórea da família Fabaceae recomendada na ornamentação de parques, praças, jardins centrais de avenidas, vias públicas e estacionamentos. Nesse sentido, o objetivo desse trabalho foi avaliar a germinação e o vigor de suas sementes quando submetidas a diferentes condições de luz e temperaturas. O trabalho foi realizado no Laboratório de Análise de Sementes do Centro de Ciências Agrárias da Universidade Federal da Paraíba, em Areia - PB, com sementes de Caesalpinia ferrea submetidas aos seguintes tratamentos: regime de luz branca, verde, vermelha, vermelho distante e escura (ausência de luz), nas temperaturas de 25 e 30°C constantes e 20-30°C alternada. As características avaliadas foram a germinação, primeira contagem e índice de velocidade de germinação, bem como comprimento e massa seca de plântulas. A germinação das sementes de Caesalpinia ferrea é favorecida pela temperatura alternada de 20-30°C e não é influenciada pelos regimes de luz, sendo a espécie fotoblástica neutra.
