Irrational use of medicinal native plants of the Center - West of Argentina has endangered the survival of numerous useful species (del Vitto et al., 2003). The “poleo” L. turbinata presents “secrets benefits” (Karlin et al., 1994) in the field of the fitomedicina and the nourishing industry. In April, 2003 mericarpos obtained of plants that grow in the Department The Capital (San Luis) were harvested. Tests were performed every two months, with temperatures that they ranged between 18 and 25 ºC, in conditions of light and darkness, and there decided the variation of the germinative power (PG) and the germinative value (VG), across the time. “Seeds” were placedby treatment (n=150) in Petri’s boxes, with absorbent paper and distilled water. There was verified that as age increases a trend for increase is observed in the PG and is eliminating the need of light. In accidental form, a test at 30°C showed a response different from the observed one at low temperatures, namely that VG and PG did not show significant differences with light an without it. Therefore, new experiences will be performed by at temperatures above 25°C. Thepercentages of germination, relatively low, might be a consequence of the employment of fruits (mericarpos) with defective seeds due to bad pollination, auto-pollination, climatic or other factors.
