Phenotypic structure of quercus robur L. Populations in bashkir cis-urals as a base of gene pool preservation of the species in the region

Populations of Quercus robur L. in Bashkir Cis-Urals are differed by morphological traits of leaves. Analysis of phenotypic structure and variability of populations allows to identify two groups of populations. Gene pool preservation of the species in the region should be based on the character of population differentiation and selection of subpopulations with the highest level of phenotypic variability.
