This study evaluated the effects of temperature and KNO3 on Tridax procumbens seed germination and dormancy. Materials and Methods: Two subsamples of 50 achenes were submitted to treatments using a factorial combination of temperature (25 and 30°C) and moistening the substrate with KNO3 solution (0% KNO3, 0.2% KNO3) in a completely randomized experimental design with five replications. Daily germination counts were made using the primary root protrusion and analyzing the accumulated germination percentage, germination speed and accumulated germination curve. Results: Germination percentage increased at the highest temperatures. In contrast, the use of KNO3 at the same temperature slightly decreased germination speed after 21 days of cultivation. The accumulated germination curve adjusted to the logistic model of all treatments showed an asynchrony in seed germination over time. Conclusion: Thus, temperature positively influenced the germination speed index at 21 days, while the presence of 0.2% KNO3 in the substrate influenced it negatively.]]>Chauhan, B.S. and D.E.
