Temperature is one of the main factors influencing on the break of physical dormancy (seed coat impermeability) and germination of tropical legume seeds. The aim of this study was to analyze the influence of alternating temperature on seed germination of two native species from Brazilian ecosystems: Sophora tomentosaand Mimosa caesalpiniifolia. To do so, seeds were subjected to two treatments: (1) constant temperature (control, 25 °C) and (2) alternating temperature (from 20 to 40°C). The seeds were placedupon Petri dishes lined with a double layer of filter paper soaked in distilled water; germination was counted for 45 days. Seeds of M. caesalpiniifoliashowed germinability from 59 to 56% either in the control and in the alternating temperature, with a germination time around 8 days, with no signs of dormancy. Seeds of S. tomentosa, also had no influence from the alternating temperature, showing a fraction of non-dormant seeds (38-39% of germination) and germination time ~20 days regardless of the treatment. Hence, alternating temperature had no effect on physical dormancy breaking, in contrast to what has been found in the literature.
