Abstract The morphometric variation of cones, seeds and needles was evaluated in two natural populations of Pinus hartwegii at Veracruz state to estimate the percentage of phenotypic variation due to differences among populations and trees within populations. In addition, multivariate principal components, cluster and discriminate analysis was conducted to characterize the populations. Most of the traits measured on cones, seeds and needles showed significant variation both among populations and among trees within populations. Measurements of cone and seed traits used as indicators of the genetic and reproductive status of two natural populations of P. hartwegii revealed that much… More >
