Resumo: This study aimed to verify the influence of the size of the diaspores and scarification treatments on the emergence rate and initial growth of Pterodon emarginatus Vog. (Fabaceae) after one year of storage. Diaspores of the species were collected, measured, weighed and separated into three size classes, with amplitude determined by the width of the fruit. Subsequently, they were submitted to thermal and mechanical scarification. A randomized experimental design was used, with 10 replicates of 10 units / each. We performed a survival analysis, besides analysis of variance and Tukey post-hoc test to verify significant differences in the percentage of diaspores emergence. We used generalized linear models to verify the variation in the initial growth of the seedlings. Our results indicated that treatments intercropped with the largest diaspore sizes positively influenced the percentage of emergence. Larger diaspores also resulted in larger diameter seedlings and stem length. Mechanical scarification led to a higher biomass allocation in the roots. We suggest that P. emarginatus diaspores should be submitted to pre-germination treatments to potentiate seedling emergence and development. We also recommend choosing the largest diaspores.

(Fabaceae) após um ano de armazenamento. Diásporos da espécie foram medidos, pesados e separados em três classes de tamanho, com amplitude determinada pela largura do fruto, sendo submetidos posteriormente à escarificação térmica e mecânica. Foi utilizado um delineamento inteiramente casualizado, com 10 repetições. Foi realizada análise de sobrevivência, além de análise de variância e pós-teste de Tukey, para verificar diferenças significativas na porcentagem de emergência dos diásporos. Para detectar a variação no crescimento inicial das plântulas utilizaram-se modelos lineares generalizados. Os tratamentos consorciados com os maiores diásporos influenciaram positivamente a porcentagem de emergência. Diásporos maiores também resultaram em plântulas com maiores diâmetros e maior comprimento do caule. A escarificação mecânica proporcionou maior alocação de biomassa nas raízes. Sugere-se que diásporos de P. emarginatus sejam submetidos a tratamentos pré-germinativos, para potencializar a emergência e formação de plântulas, sendo recomendada a seleção dos diásporos maiores.
