Abstract

This research verified the influence of the temperature and light on seed germination of Bowdichia virgilioides. The experiment was conducted in factorial system 3x5x2, correspoding to three lots of seeds, five temperatures and two light condictions. The germination test was conducted in thermo gradiente table regulated in temperatures of 20°C, 25°C, 30°C and 35°C under constant light and BOD adjusted in temperature 20-30°C with photoperiod of 12 hours. In order to simulate the light absence the gerbox were involved with alluminium paper. There were evaluated the percentage of germination, index speed of germination and dry weight of seedlings. The tempeatures of 25°C and 20 30°C result in higher percentage. In relation to photoblastism, the seeds are indifferent to light conditions.
