Plantago tomentosa Lam. (Plantaginaceae) is used in the popular medicine as anti-tumoral, antimicrobial and anti-inflammatory agent. This propagation is basically done by seeds, which the publications available are scarce. The objective of this research was to study the influence of the light, temperatures and substrate on the total percentage of germination/emergency and index of germination/emergency speed. There were used different temperatures (15, 20, 25, 30 and 35°C constant and, 15-25°C and 20-30°C alternated) in the absence and presence of constant light. The substrate tested were subsoil sand, land, vermiculite and Plantmax®, besides the subsoil land combination, in the ratio of 1:1. the results suggest that Plantago tomentosa seeds was a positive photoblastic behavior, independent of the tested temperature. The use of constant temperature of 15 and 20°C and alternated (15-25°C) promated a higher vigor expression. The substrate sand is recommended for the emergency study.
