Recent research in forest species seeds has been developed,aiming to reduce the time required to obtain viability results,from the verification of the most appropriate methodology of tetrazolium test for each species, according to work carried out by Fava and Albuquerque (2013) on Palicourea rigida Kunth; Abbade and Takaki (2014) on Tabebuia roseoalba (Ridl.) Sandwith; Cripa et al. (2014), Kaiser et al. (2014) and Lamarca and Barbedo (2014) on species of the genus Eugenia; and Nogueira et al. (2014) on Pacara Earpod Tree (Enterolobium contortisiliquum (Vell.) Morong).
