The transformation that taking place during of spontaneous cultivars introduction have not taken into consideration for last 10 years. The plants introduction in the Botanic Garden PSU have a planned character in a northwest middle taiga. Decorative arboretum was laid in 2000 (Potapova, Prokhorov, 2010). By 2014, the conifers collection includes 159 specimens of 98 cultivars belonging to 28 species, 10 genera and 3 families (Cupressaceae, Pinaceae, Taxaceae). Taxa are presented as species with narrow native habitat (Microbiota decussata, Thujopsis dolabrata, Chamaecyparis pisifera, Picea omorika), and with a wide (Juniperus communis). Plants were planted gradually. Annual plant monitoring include measuring of height, width of the crown, trunk diameter, needles color, seed-bearing, damage. Based on the study was identified plants groups in growth rate, seed-bearing. The number of generative samples are increased from 17 to 53% during 2007-2014. Seed-bearing is not a constant parameter and depends on a complex of abiotic factors.
