Resumen:
This work focuses on the genetic study of Pinus patula Schiede ex Schltdl. & Cham., the most important species in the forest sector of the Sierra Juarez in Oaxaca, in order to evaluate the effect of forest management on genetic diversity of reforested sites and natural regeneration. It also seeks to determine whether the intensive logging of the mid-twentieth century genetically impoverished the species. Three microsatellites were used for six sites, covering three forest areas that had been managed for one, five and eighteen years, and three areas of natural regeneration. The resulting allelic richness (A(o) = 59 and A(e) = 16) and genetic diversity (H-e = 0,802) was high, and there were no significant differences in genetic diversity between managed and natural regeneration sites. However, there was a lack of genetic structure (F-st = 0,056) at sites with moderate gene flow (N(e)m = 4,19). Furthermore, UPGMA cluster analysis suggested that the genesis of individual trees in the manag
