The analysis of variability of needle quantitative characteristics in the Scotch pine (Pinus sylvestris) population

In the article the author examines the variability of quantitative characteristics of needle in three chronologically related populations of Scotch pine ( Pinus sylvestris ). The levels of their individual variability are defined. The author also gives the evaluation of intrapopulation and interpopulation heterogeneity of needle selection according to the examined characteristics. The author makes an assumption that the index of the form of needle cross-section may be viewed as the pointer token of this population.
