Polimorfismo proteico en Pinus hartwegii Lindl. del Cofre de Perote, Veracruz, México

we evaluate the globulins and total proteins composition in megagametophytes tissue from seeds collected in a natural population of pinus hartwegii located at cofre de perote, veracruz. electrophoresis was performed in a discontinuous system of polyacrylamide gels (page). results shown a good resolution and repeatability in obtained protein profile. it was detected the presence of four haplotypes. the trees under study were classified in three groups. the group i that contained the majority of evaluated trees (70 %), was characterized for the presence of haplotype i. our results suggest the presence of certain inbreeding degree in this population.
