Abstract: Dubravos arboretume nuo 2005 m. kaupiamos ir tiriamos sumedėjusių augalų atmainos, morfologiniais požymiais besiskiriančios nuo tipinių savo rūšies atstovų. Šiuo metu auginama 14 paprastosios eglės atmainų pavyzdžių. Devyni kilę iš „Raganų šluotų“, kiti yra miškuose, daugiausia Kauno rajone, augančių paprastųjų eglių sėjinukai. Dauguma augalų yra dekoratyvūs ir galėtų būti dauginami bei platinami kaip vietiniai, auginti Lietuvos sąlygomis puikiai tinkantys sodinukai įvairiems želdynams, o kai kurie ateityje galėtų tapti ir naujomis registruotomis veislėmis. Morfologinės vietinių medžių atmainos svarbios ir genetinės miškų įvairovės išsaugojimui, taip pat mokymui, visuomenės švietimui gamtos mokslų ir gamtosaugos srityse. Ateityje Dubravos arboretume šių augalų kolekcija bus toliau gausinama ir tiriama.
One of the aims of Dubrava Arboretum is collecting, evaluating and conserving bioecological diversity of native Lithuanian flora. Since 2005, native woody plants with atypical morphological features in Dubrava Nursery, Girionys Park, Dubrava Forest Enterprise plantations, other locations and in the wild are identified and registered. These plants are propagated by grafting, budding or cuttings and grown in Dubrava arboretum. Some fruiting plants are propagated by seeds. At present day 14 examples of Picea abies (L.) H. Karst. selections with atypical morphological features are collected in the Arboretum. Most plants – 9 examples – come from “Witches’ Broom” found in forests. The others are seedlings of typical Norway spruce. To date, our findings suggest that the plants are different and distinguishable from other cultivars of Norway spruce by their morphological and ornamental features. 7 selections are highly decorative and in the future will be able to be registered as new cultivars. Collecting and conserving the variety of local wild plants help to maintain genetic diversity in our forests. Selections from the wild can serve as a source of locally adapted propagation material. Our collection of Norway spruce selections as well as other collections are available for public and are used for public education in botany, forestry, ecology, gardening, landscape research and related subjects. Dubrava arboretum is intended to continue collecting and researching new morphological selections of spruce and other woody plants in the future too. Past experiences suggest that over the next decade our collection will increase to the number of approximately 30 selections.
