Evaluation of the energy of lying generative organs of hazelnuts in the Urals

Abstract

Hazel on the eastern slope of the Ural Mountains is an introduced species. In the conditions of the Chelyabinsk region, it is widely represented in amateur gardening. Plants hibernate normally and bear fruit. In the conditions of the Middle Urals, hazel is prone to freezing of male aments and is less productive. The origin of the Ural introduced hazel population is related both to the direct transfer of plants from the natural habitats of the species, as well as to the re-sowing of seeds from the hardiest cultivars of Kudasheva R.F., and local controlled hybridization. Growing in different conditions, it is difficult to objectively assess the yield of plants of different ages. The energy assessment of the laying of generative organs made it possible to identify potentially productive forms. In the Botanical Garden, the forms Botanic and Botanic 2 have been isolated from the controlled crossing of Corylus avellana x Hazelnuts. At the Sverdlovsk Horticulture Breeding Station, the forms №5, №6, №7, №14. The forms Urozhodnaya, Vost 1, Sev 5, Sev 7 were selected from the personal collection near Chelyabinsk. In such forms, the female inflorescence accounts for less than 20 cm of annual growth or less than 5 buds, or about 5 aments.
