Resumo

The use of chia seeds as food is increasing as well as its culture, which leads to the need for quality moni­toring of seeds and the establishment of standards for such, non-existent in Brazil. This paper evaluates the effect of two temperatures (18 and 25 °C) and three substrates (between-paper, on-paper and paper-roll) on chia seed germination. A completely randomized design in 2 x 3 factorial arrangement with four replications of 100 seeds was carried out. Each replicate was individually wrapped in gearbox box kept in chambers of BOD (18 °C) and Mangelsdorf (25 °C). The evaluation of the percentage of germination was performed on 7 and 14 days by counting the germinated seeds. There was no interaction between factors and the tempera­ture of 25 °C showed better results for the germination of chia seeds (95%), regardless of substrates. The paper-between substrate performed best showing 84% germination at 18°C.
