ABSTRACT
Light and temperature are considered environmental factors of great importance in germination control. With the purpose of evaluating the effects of light quality and temperature on germination, the fruit-seeds of Triplaris surinamensis were placed on germination paper, previously wetted with distilled water, and submitted to white, red, clear red and dark light at constant temperatures of 25 and 30º C. The results show that the seeds germinate very well when submitted to white and red light at 25 and 30°C. Therefore, Triplaris surinamensis is positive photoblastic and germinates better under conditions of open area or of large forest clearings; however, it can also germinate in conditions of little light or in darkness.
