Growth and development characteristics of introduced conifers in national arboretums in Ivano-Frankivsk region
Journal Title: Лісівництво і агролісомеліорація - Year 2016, Vol 129, Issue
Abstract
The article deals with the study of growth and development peculiarities of the introduced coniferous species on the conservation area – the largest national arboretums on the Northeastern megaslope of the Ukrainian Carpathians, “Vysokohirnyy” and “Dibrova”. The presence and taxonomic structure of the species, ecotypes and forms were determined and their current status, parameters of growth, development, stability, quality, decorative value and overall prospects for use in plantations of different purpose were studied. The mean annual height and diameter growth indices of the introduced species during ontogeny were estimated. The dynamics of seasonal growth, potential plants reproducibility and correlations between resistance and seed production were investigated. A comparative assessment of bio-ecological features of adaptation of exotic species at different hypsometric levels of growth was done. The most prospective species for medium and high mountain forestry were: Larix laricina (Du Roi) C. Koch, L. decidua L. kaempferi, L. kaempferi (Lamb.) Carriere, (Picea sitchensis (Bong.) Carriere, Pseudotsuga menziesii (Mirb.) Franco, Abies nordmanniana (Steven) Spach and A. balsamea (L.) Mill. For foothills and lowland, Larix decidua L., L. polonica (Racib.), L. kaempferi (Lamb.), Pseudotsuga menziesii (Mirb.) Franco, and Pinus pallasiana D. Don were the most promising.
