Resumo: | The study was conducted to evaluate different volumes (mL) of water and substrate temperatures (° C) in germinating seeds Gao Mulateiro (Peltogyne paniculata Benth.). The seeds were germinated in roles germitest paper (three sheets / roll), previously moistened with distilled water equivalent to 1.5; 2.0; 2.5 and 3.0 ml / g paper, without further addition of water. The roles were packed in transparent plastic bags of 0.04 mm and placed in a chamber with constant temperatures of 25, 30 and 35 ° C. The evaluation parameters were: germination percentage, speed of germination, length of the primary root and hypocotyl. The experimental design was completely randomized, factorial 4 x 3 Each treatment consisted of 100 seeds (four replicates of 25 seeds per treatment). The different water levels and temperature influenced both the percentage and the germination rate of the species under study. The best temperatures for all parameters evaluated were 25 and 30 ° C. 0 water flow of 2.5 mL / g paper showed better percentage and germination speed index (GSI), and 3.0 mL / g paper favored the lengths of primary root and hypocotyl. |

As sementes foram colocadas para germinar em roles de papel germitest (três folhas/rolo), previamente umedecidos com água destilada equivalente a 1,5; 2,0; 2,5 e 3,0 mL/g papel, sem adição posterior de água. Os roles foram acondicionados em sacos plásticos transparentes de 0,04 mm e colocados em câmara com temperaturas constantes de 25, 30 e 35 °C. Os parâmetros de avaliação foram: porcentagem de germinação, índice de velocidade de germinação, comprimento da raiz primaria e do hipocótilo. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 4 x 3. Cada tratamento foi composto por 100 sementes (quatro repetições de 25 sementes por tratamento). Os diferentes volumes de água e níveis de temperatura influenciaram tanto a porcentagem quanto a velocidade de germinação da espécie em estudo. As melhores temperaturas para todos os parâmetros avaliados foram de 25 e 30 °C. 0 volume de água de 2,5 mL/g papel mostrou melhores percentuais e índices de velocidade de germinação (IVG), e o de 3,0 mL/g papel favoreceu os comprimentos da raiz primaria e do hipocótilo.Universidade Federal Rural da Amazônia/UFRA2011-05-25info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/243Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 48 No 1 (2007): RCA; 193 - 204Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 48 n. 1 (2007): RCA; 193 - 2042177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
