Resumo: | The mororó ( Bauhinia forficata Link ) is a species of the Caatinga forest that can be used in reforestation programs . However , initial studies on the germination of seeds needed , which may present impediments or require optimal germination temperature ranges to maximize the process of germinação.Por because of the importance of this species and the scarcity of studies of germination for reforestation have successfully are this research was carried out with the aim of studying the efficiency of pre -germination treatments and the influence of temperature on seed germination mororó . Two experiments were conducted at the Federal University of Alagoas , Campus Arapiraca , completely randomized , with the experiment 1 with four replications of 25 seeds and experiment 2 with five replicates of 25 seeds . In the first experiment, the seeds were germinated following pre - treatments : immersion in water at 80 ° C for 2:05 min; chemical scarification for 5 , 10 and 15 min; mechanical scarification , soaking in distilled water , and the witness, analyzing variables : percentage of germination ( GER ) , germination speed index (GSI ) , mean germination time (MGT ) , emergency ( HRMS) , emergence rate index (EVI ) and mean emergence time ( TME ) . The second experiment evaluated the effect of different temperatures ( 15 , 20 , 25 , 30 , 35 , and 40 ° C ) in variables related to germination ( GER , IVG and TMG ) . The seeds were immersed in sulfuric acid for 5, 10 and 15 min and the temperature between 24.3 and 26.7 ° C provide efficient germination of seeds mororó . |

No entanto, para o reflorestamento possuir êxito são necessários estudos iniciais sobre a germinação das sementes, as quais podem apresentar impedimentos germinativos ou exigir faixas ótimas de temperatura para maximizar o processo de germinação.Por causa da importância dessa espécie e a escassez de estudos de germinação, realizou-se essa pesquisa com o objetivo de estudar a eficiência de tratamentos pré-germinativos e a influência da temperatura na germinação das sementes de mororó. Foram realizados dois experimentos na Universidade Federal de Alagoas, Campus Arapiraca, em delineamento inteiramente casualizado, sendo o experimento 1 com quatro repetições de 25 sementes e o experimento 2 com cinco repetições de 25 sementes. No primeiro experimento as sementes receberam os seguintes tratamentos pré-germinativos:imersão em água a 80 °C por 2 e 5 min; escarificação química por 5, 10 e 15 min; escarificação mecânica; embebição em água destilada; e a testemunha, analisando-se as variáveis: percentagem de germinação (GER), índice de velocidade de germinação (IVG), tempo médio de germinação (TMG), emergência (EMER), índice de velocidade de emergência (IVE) e tempo médio de emergência (TME). No segundo experimento avaliou-se o efeito de diferentes temperaturas (15, 20, 25, 30, 35, e 40 °C) nas variáveis relacionadas à germinação (GER, IVG e TMG). A imersão das sementes em ácido sulfúrico por 5, 10 e 15 min e as temperaturas entre 24,3 e 26,7 °C proporcionam eficiente processo germinativo das sementes de mororó.
