Interpopulational variability of Pinus uncinata Ramond ex DC. in Lam. & DC.(Pinaceae) cone charactersDendrobiology 2004, vol. 51: 43-51 Full text (pdf)
Abstract: Abstract: The characteristic of Pinus uncinata on the basis of biometrical analyses of 16 cone features was done. The research was based on 8 samples representing 6 populations, consisting of 50 cones each, collected in the Pyrenees, within the natural range of the species. All the investigated cone features were moderately differentiated, with the variation coefficient ranging from 8 to 30%. The particular populations differ significantly from each other statistically according to several features examined. The samples collected in the same population also vary significantly. The differences between populations, however, do not enable their division into groups, which supports their origination from the same Pleistocene refugia.
