Resumo: This research had as objective to evaluate the germination and emergence speed index (ESI) of pequi (C. brasiliense Camb.) from sexual propagation material (putamens and seeds) fromtwo sites, Porangatu and Faina, Goiás State, Brazil. Twelve treatments were evaluated (2x6 factorial), the two procedences being combined with six sowing methods: putamens (inner mesocarp and endocarp) immersed in water; putamen without pulp (inner mesocarp) immersed in water; seeds (almonds) immersed in water; putamens immersed in giberelic acid solution 10%; putamens without pulp immersed in giberelic acid solution; seeds (almonds) immersed in giberelic acid solution. The experimental design was randomized complete blocks with four replications. The experiment took place in a screen-house at 50% shading. The observations were taken every 48 hours for 77 days from seed planting. It was not observed significant variation (p>0.05) between fruit origin in germination and ESI. Putamens with or without pulp and treated with giberelic acid resented satisfactory germination indexes, above 30%, and perior (p0.05) in this characteristic. Besides, significant (p>0.05) effect of the treatments was not detected on plantules ESI.KEY-WORDS: Pequi; GA3; giberelic acid; almond; native species.

Este trabalho teve como objetivo avaliar a germinação e o índice de velocidade de emergência (IVE) em pequizeiro (Caryocar brasiliense Camb.), a partir de material de propagação sexual (putámens e sementes) provenientes de dois locais, Porangatu e Faina, no Estado de Goiás. Foram avaliados doze tratamentos (fatorial 2x6), sendo as duas procedências combinadas com seis formas de semeadura: putámens (mesocarpo interno e endocarpo) imersos em água; putámens sem polpa (mesocarpo interno) imersos em água; sementes (amêndoas) imersas em água; putámens imersos em solução de ácido giberélico 10%; putámens sem polpa imersos em solução de ácido giberélico; sementes imersas em solução de ácido giberélico. O delineamento experimental foi blocos ao acaso, com quatro repetições. O experimento foi conduzido em telado com 50% de sombreamento. Foram feitas observações a cada 48 horas, por período de 77 dias, contado a partir da semeadura. Não se observou variação significativa (p>0,05) entre as procedências dos frutos, tanto em germinação como em IVE. Putámens com ou sem polpa e tratados com ácido giberélico apresentaram índices de germinação satisfatórios, acima de 30%, e superiores (p0,05) para esta característica. Ademais, não se detectou efeito significativo (p>0,05) dos tratamentos sobre o índice de velocidade de emergência das plântulas.
