RUSSIAN JOURNAL OF FOREST SCIENCE, 2019, No. 3, P. 208-214 POPULATION VARIABILITY OF FINNISH SPRUCE FROM THE SEED SCALE FORM IN NORTHERN ARKHANGELSK OBLAST S. N. Tarkhanov Federal center of integrated Arctic research Severnaya Dvina emb. 23, Arkhangelsk, 163000, Russia E-mail: tarkse@yandex.ru Received 16 April 2015 Variability of spruce ( Picea obovata Ledeb. × Picea abies (L.) Karst.) in basins of Northern Dvina, Onega and Pinega Rivers in northern Arkhangelsk Oblast was inferred from the morphometry of ripe cones and the form-factors of seed scales. Siberian and transitional (allied to Siberian) forms dominated, representing 70-95% of the total count, in populations growing in northern taiga. Mature spruce trees with different types of seed scales did not differ significantly in stem or crown dimensions, in number of lateral shoots, buds and longevity of needles. The northernmost (64-65°N) and the easternmost (43-44°E) populations of spruce had significantly lower length and dry mass of the cones than westernmost (38°E) and southernmost (63°N). Morphometric parameters of ripe cones had no correlation with the form-factor (elongation factor) of the seed scales within single population. Keywords: spruce, populations, variability, forms of seed scales, elongation factor, morphometry of cones, northern Arkhangelsk Oblast.
