This further suggests that, in the future, this method of 130 110 propagation will be of the utmost importance in the production, 90 Floration phase Vegetation phase 70 preservation and conservation of the above mentioned species. 50 Mentha Mentha According to other works in Portugal, we didn’t find seeds in Mentha cervina pulegium Figure 2- Phenological evolution, from March to July 2002 cervina, whose results are only in vegetative propagation.
