We compared germination and seedling emergence in selfed and open-pollinated progenies obtained from eight passion fruit vines (genotypes). Self-pollination was performed at the button stage to overcome self- incompatibility. The experiment was a randomized bloc k design in a factorial scheme (2 x 8; type of progeny x genotypes) with four replicates and 50 s eeds per experimental unit. At 14, 21 and 28 days after sowing, the germination percentage and the emergenc e speed index were analyzed. The total length of seedlings (cm), shoot length (cm), radicle length (cm) and total dry matter of seedlings (g) were evaluated 28 days after sowing. The mass of 100 seeds (g) was de termined before sowing. Differences were noted between genotypes and progeny types with respect to germination and emergence speed. In general, seeds obtained by selfing exhibited earlier germination and a higher emergence speed. It was concluded that seed dormancy is associated with the genotype of the em bryo and is most likely conditioned by a dominant genetic effect. 2015 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303042425012 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
