CHAVES, Izabel de Souza et al. Germination of Miconia ligustroides (Melastomataceae) diaspores submitted to different treatments for dormancy overcoming. Rev. bras. Bot. [online]. 2011, vol.34, n.3, pp.335-341. ISSN 0100-8404. http://dx.doi.org/10.1590/S0100-84042011000300008.
To assess the germination behavior of Miconia ligustroides (DC.) Naudin, diaspores were submitted to different regimes of temperature, light and substrate. Due to intrinsic low germination of the diaspores, they were submitted to treatments that aimed to overcome endogenous and exogenous dormancy. Miconia ligustroides presents complex dormancy and to overcome it is recommended to soak the diaspores in H2SO4 diluted at 75% for 5 minutes, wash it and then soak it in a solution of 400 mg L-1 of GA3 for 12 hours. Seeding should be done on Germtest® paper at 25 °C.
