Resumo: Schizolobium parahyba (Vell.) Blake, known guapuruvu can be used in building, popular medicine and to forest restoration in riparian areas. There are little informations about its seed quality evaluation. The objectives of this work were to evaluate the temperature influence on seed germination and to test the tetrazolium salt efficiency to determine seed viability. Two seed lots were harvested in Machado s region – MG. To accelerate the germination process seed dormancy was broken with a cut in apical part and the pathogens incidence reduction was done by washing in sodium hipoclorite (2%). The seeds were sowed in poliethylen boxes (35x20x5cm) with sand as washed and sterilized at 120ºC by 20 minutes as substrate. Seeds were maintained at constant temperatures 25ºC, 30ºC and 35ºC with continuous light and at alternate temperatures 20-30ºC, with 8 hours of light. The evaluations were realized considering root emergence, normal seedlings and speed germination index. For tetrazolium test, after immersion of seeds were immersed 48 hours and to seed coats removal the embryos were kept in tetrazolium salt at 0,05% and 0,1%, at 30ºC into a germination chamber (BOD) in dark by 5 hours. In the germination tests, the temperatures at 25ºC and 35ºC promoted higher germination percentage and speed germination index than the other temperatures. In the tetrazolium test the concentration 0,05% was better than 0,1% promoting a more efficient evaluation of seed viability of this species and all the classes obtained were efficient to evaluate the seed viability.

Blake, conhecido como guapuruvu, pode ser utilizado na construção civil, na medicina popular e apresenta potencial para uso na recuperação de matas ciliares. Poucas informações são encontradas na literatura sobre avaliação da qualidade fisiológica de sementes dessa espécie, principalmente em relação a metodologias para realização dos testes de germinação e tetrazólio. Objetivou-se com este trabalho avaliar a influência da temperatura no teste de germinação e da concentração da solução no teste de tetrazólio para avaliação da viabilidade de sementes de S. parahyba. Sementes de dois lotes tiveram seus ápices cortados, as quais foram desinfestadas com hipoclorito de sódio e semeadas em bandejas de polietileno (35x20x5cm), sobre areia peneirada, lavada e autoclavada (120ºC por 20 minutos). As sementes foram submetidas à temperaturas constantes de 25ºC, 30ºC, 35ºC sob luz contínua, e alternada de 20-30ºC com 8 horas de luz na temperatura de 30ºC. As avaliações foram realizadas considerando-se a emergência de radícula, plântulas normais e índice de velocidade de germinação. Para o teste de tetrazólio, após a imersão das sementes em água por 48 horas, os tegumentos e o endosperma foram removidos e os embriões imersos nas soluções de tetrazólio a 0,05% e 0,1% e mantidos em câmara de germinação tipo BOD no escuro por 5 horas a 30ºC. Nos testes de germinação, as temperaturas de 25ºC e 35ºC proporcionam maior porcentagem e velocidade de germinação de sementes de S. parahyba e no teste de tetrazólio, a concentração 0,05% da solução permitie avaliar, com eficácia, a qualidade dos lotes de sementes desta espécie.Londrina, PRporAssociação Brasileira de Tecnologia de SementesRevista Brasileira de SementesTeste de germinaçãoTeste de tetrazólioGuapuruvuGermination testTetrazolium testComparação da viabilidade de sementes de Schizolobium parahyba (Vell.)
