Iheringia, Série Botânica (e 2021016) 76: 1-11, DOI: 10.21826/2446-82312021v76e2021016, URL: dx.doi.org/10.21826/2446-82312021v76e2021016 ABSTRACT – Imbibition curve, anatomy and mobilization of reserves in seeds of Mimosa flocculosa Burkart submitted to overcoming of dormancy.

This study aimed to expand knowledge about Mimosa flocculosa Burkart seed germination and efficiency of break dormancy treatments, focusing on hydration, reserves mobilization, integument anatomy and seed germination.We conducted a hydration curve, and from that, we stipulated a three-phase profile for each treatment: control, water at 80 ºC for 10 min and sulfuric acid 98% for 3 min. Sugars and proteins, integumentary anatomy and germination parameters (germination percentage, frequency and synchrony of germination) were analyzed during hydration.Our results showed that the overcoming dormancy methods used in M. floculosa seeds are indicated, since they improved germination, uniformed hydration, presented integument fissures and destabilizations increasing water uptake and germination synchrony.
