Resumo: The work had as objectives to evaluate the influence of the light, temperature, and chemical scarification on the germination of seeds of S. virgata, species still little studied and that is invasive in several niches of the caatinga ecosystem. The seeds of S. virgata were collected in the municipal district of Natuba-PB in March/2008. Eight treatments were used as follows: intact seeds in the presence and absence of light, at 25ºC; intact seeds in the presence and absence of light, at 30ºC; submerged seeds in sulfuric acid for five minutes in the presence and absence of light, at 25ºC; submerged seeds in sulfuric acid for five minutes in the presence and absence of light, at 30ºC. The germination tests were accomplished in germination cameras under light and continuous darkness at constant temperatures of 25ºC and 30ºC, in a 12 hours photoperiod. The seeds were put to germinate in plastic boxes (gerbox) with filter paper. The seeds of S. virgata have tegument dormancy and show low germination tax when intact, which is a strategy for seed banks formation. The acid scarification increased germination percentage and speed germination index.

Este trabalho teve como objetivos avaliar a influência da luz, da temperatura e da escarificação química sobre a germinação de sementes de S. virgata, espécie ainda pouco estudada e que se constata invasora em diversos nichos do bioma Caatinga. Sementes de S. virgata foram coletadas no município de Natuba-PB em março de 2008 e submetidas a oito tratamentos, descritos a seguir: sementes intactas, na presença e ausência de luz, a 25ºC; sementes intactas na presença e ausência de luz, a 30ºC; sementes imersas em ácido sulfúrico por cinco minutos na presença e ausência de luz, a 25ºC; sementes imersas em ácido sulfúrico por cinco minutos na presença e ausência de luz, a 30ºC. Para estimar os efeitos dos tratamentos foram realizados testes de germinação em câmaras de germinação sob luz e escuro contínuo a temperaturas constantes de 25ºC e 30ºC, em fotoperíodo de 12 horas. As sementes foram colocadas para germinar em caixas Gerbox forradas com folha de papel de filtro. Constatou-se que as sementes de S. virgata possuem dormência tegumentar e tem baixa porcentagem de germinação quando intactas, o que constitui uma estratégia para formação de bancos de sementes. A escarificação ácida provocou aumento da germinação e da velocidade de germinação das sementes.UEL2010-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/197810.5433/1679-0359.2010v31n4p889Semina: Ciências Agrárias; Vol. 31 No. 4 (2010); 889-894Semina: Ciências Agrárias; v. 31 n. 4 (2010); 889-8941679-03591676-546Xreponame:Semina.
