The “poleo” Lippia turbinata presents “secret benefits “ in the field of the phytomedicine and the nourishing industry. Diverse studies demonstrate that the germinative power (PG) in poleo and other native species is relatively low. In these species the in vitro germination with special conditions and way of culture has had major success. These results might answer to the lack of substances of reserve for the embryo and/or to ecological factors that affect the germination. Essays were carried out by seeds (mericarpos) of poleo of 14 months of age. They were made to germinate in two different laboratory conditions: 1-conventional germination with the StandardTest and 2- in vitro germination, with means N6 and N650%. The PG obtained in the essays was: 26.1% for the Standard Test; 31.25% and 44,08% in the in vitro germination with the means N6 and N650% respectively. These results would indicate that the lack of reserves (related to the size) plays an important role in the viability and the germination of these seeds, which might imply the need of other organisms of the soil that help to their absorption of nutrients.
