Journal Title: Лісівництво і агролісомеліорація - Year 2018, Vol 133, Issue
Abstract
The article reports results of the investigation of the 33-year-old experimental plantation of Sugar maple in conditions of fresh maple-lime oak forest site in Kharkiv region, the purpose of which was to determine the species suitability for using in the region. Evaluation of 7 variants was carried out by a set of indicators, which included growth, quality, condition and reproduction. There was no significant difference between the variants by growth indices. All the variants lagged behind control (English oak) in diameter. Two of seven variants exceedappropriate control indicator in height and the rest insignificantly lagged behind it. The trend of best growing in height of trees of southern origin, discovered as early as 4 years old, has continued. The share of trees of I and II selection categories in variants ranged from 0 to 18.2%, the majority of trees had a satisfactory and good condition. According to the results of a comprehensive assessment, 6 of 7 variants wereassigned to the second group of perceptivenessand recognized as suitable for the introduction into the composition of plantations, which will perform recreational and protective functions under medium anthropogenic loading, and for greening non-industrial zones of cities.
