Abstract: Germination is the phase of the life cycle that determines the distribution of plants. The study of the ecology of this process and knowledge of seed biology can be of great value in understanding the stages in the establishment of a plant community, as well as its survival and natural regeneration. Therefore, relating seed size to germination and emergence is essential for seedling establishment, which could assist in projects linked to the recovery of degraded areas, reforestation and the production of seedlings in nurseries. In order to verify the effect of seed size on seedling germination and emergence, the seeds of tree species were separated according to seed size, with T1 representing small seeds and T2 representing large seeds. The germination bioassays were carried out using a germination chamber and the analysis of seedling emergence took place in a greenhouse. On average, large seeds (T2) of Inga vera showed a higher germination percentage and a higher speed germination index, with no significant difference observed in relation to mean germination time. For Poecilanthe parviflora, T2 seeds showed a higher germination percentage and a higher speed germination index. Large seeds of Cariniana estrellensis showed a lower germination percentage, and medium seeds did not differ from small and large seeds in relation to this parameter. In general, seed size influenced the performance of I. vera and P. parviflora, however, it did not interfere with the germination and emergence of C. estrellensis.
