The objective of this study was to test different substrates and temperatures in the germination and seedling formation of <em>B. antiacantha</em>. Seeds obtained from fruits collected in situ from three localities, one in Paverama/RS and two in Taquari/RS, were washed in running water and homogenized in a single batch. After drying, the seeds were disinfested and seeded in medium sand and germibox paper, and exposed to constant temperatures of 25 and 30ºC. Firstly, the water content of the seeds were determined and, after installation of the experiment, the percentage of germination (G) and seedlings formed (SF), germination mean time (MTG) and seedling formation mean time (MTS), germination rate index (GRI) and seedling formation rate index (SRI) were calculated. The experimental design was completely randomized, in a 2 x 2 factorial arrangement with 4 replicates of 50 seeds. The water content and the weight of one thousand seeds corresponded to 17.02% and 27.09 g, respectively. The paper was superior to sand, with an average of 87% of germinated seeds, as well as a percentage of 86.25% of normal seedlings formed. Regarding the temperature, at 25 ºC, the seeds showed lower MTG and MTS and higher GRI and SRI. <em>B. antiacantha</em> seeds showed superior germination and initial seedling formation when sown on paper substrates and at 25 °C.</p>}, journal={Ciência e Natura}, author={Paim, Luciana Pinto and Avrella, Eduarda Demari and Caumo, Monique and Alves, Luciano Silva and Almeida, Gabriel Wathier and Rodrigues, Kétlin Fernanda and Hoehne, Lucélia and Ethur, Eduardo Miranda and Freitas, Elisete Maria de and Fior, Claudimar Sidnei}, year={2021}, month={Mar.}, pages={e27} }
