ABSTRACT

The study exposed in this paper aimed at evaluating the influence of light, temperature and presence or absence of mesocarp in seeds on the germination of Euterpe edulis Mart. (juçara-palm). The germination of seeds with and without mesocarp was assessed in the presence of light (12 h photoperiod) or in the darkness, and at temperatures of 25, 28 or 30C. A complete randomized 2x2x3 (mesocarp presence, light conditions and temperatures) factorial design was used. The seed germinability and the Germination Speed Index (GSI) were evaluated. Seeds of E. edulis were indifferent either to the presence of light or to temperatures of 25, 28 and 30C. The germinability of the seeds with mesocarp was lower (6 to 10%) than those without mesocarp (47 to 75%).


O objetivo deste estudo foi avaliar a influência da luz, temperatura na germinação do fruto com ou sem mesocarpo (despolpado) de Euterpe edulis Mart. (palmiteiro-juçara). Sementes com e sem mesocarpo foram submetidas a presença de luz (fotoperíodo de 12 h) ou escuro contínuo e às temperaturas de 25, 28 ou 30 oC. O delineamento experimental foi inteiramente casualizado, em arranjo fatorial 2x2x3 (presença de mesocarpo, regimes de luz e temperaturas). Avaliou-se a germinabilidade e o índice de velocidade de germinação das sementes (IVG). As sementes de E. edulis comportaram-se indiferentes à luz e às temperaturas de 25, 28 e 30 oC. A germinabilidade das sementes com mesocarpo foi menor (6 a 10%) que das sementes sem mesocarpo (47 a 75%).
