pine-oak forests of San Juan Nuevo, Michoacan are dominated by Pinus pseudostrobus, P. devoniana and P. leiophylla. The patterns of genetic variation of these species are poorly known, particularly those of P leiophylla, limiting the creation of guidelines for the movement of seeds and seedlings for reforestation and climate change adaptation. Species were collected in four or five provenances along an altitudinal transect (1,650 to 2,500 m) for the establishment of a nursery trial, with the aim of quantifying the genetic variation among and within species. Plant height (three and five months) was significantly different (P %26lt; 0.0001) among species. Significant differences among provenances for P. devoniana (P %26lt; 0.0001) and P. leiophylla (P = 0.0352) were observed. The species P. devoniana showed a pronounced growth pattern associated with altitude of origin, where the fastest growing plants came from a lower elevation. The populations of P leiophylla were different only at three months of age, with no statistically significant altitudinal pattern. No significant differences were found among populations of R pseudostrobus.
