Resumo: | Abstract: The study aimed to assess the influence of temperature and light on germination of Passiflora incarnata L seeds. The treatments consisted of five temperature conditions (25, 30, 35, 20-30 and 30-20 °C) and two light conditions (constant light and constant darkness). The experimental design was completely randomized in a 2 x 5 factorial arrangement (light x temperature). The seeds were kept in a germination chamber during the period of 30 days. The germinated seeds were counted daily. At the end of the experiment, the percentage of seed germination (PSG), germination speed index (GSI), the germination rate (GR) and relative frequency of germination (RFG) were calculated. The data obtained were subjected to analysis of variance and means were compared by Tukey test at 5% probability. The relative frequency of germination was represented as graphs. It was observed that light has an inhibitory effect on seed germination. The constant temperature of 35 °C and the alternating temperatures of 30/20 °C promoted a higher germination seed index for Passiflora incarnata. |

Os tratamentos foram constituídos de cinco condições de temperaturas (25, 30, 35, 20-30 e 30-20 ºC) e duas condições de luz (luz constante e escuro constante). O delineamento utilizado foi o inteiramente casualizado, em esquema fatorial 2 x 5 (luz x temperatura). As sementes foram mantidas em câmera de germinação durante o período de 30 dias. A contagem das sementes germinadas foi realizada diariamente. Ao final do experimento foram calculados a porcentagem de germinação, o índice de velocidade de germinação - IVG, a velocidade de germinação - VG e a frequência relativa de germinação. Os dados obtidos foram submetidos à análise de variância e as médias comparadas pelo teste Tukey a 5% de probabilidade de erro. A frequência relativa de germinação foi representada na forma de gráficos. Observou-se que a luz tem efeito inibitório sobre a germinação das sementes. A temperatura constante de 35 °C e a alternada 30/20 °C promoveram maior índice de germinação das sementes de Passiflora incarnata.Universidade Estadual de Maringá Centro de Ciências AgronômicasUniversidade Estadual Paulista Júlio de Mesquita Filho Departamento de BotânicaUniversidade Estadual Paulista Júlio de Mesquita Filho Departamento de BotânicaABRATES - Associação Brasileira de Tecnologia de SementesUniversidade Estadual de Maringá Centro de Ciências AgronômicasUniversidade Estadual Paulista (Unesp)Zucareli, ValdirHenrique, Luma Alana VieiraOno, Elizabeth Orika2018-11-12T17:28:08Z2018-11-12T17:28:08Z2015-06-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article162-167application/pdfhttp://dx.doi.org/10.1590/2317-1545v37n2147082Journal of Seed Science.
