Subject of research in this article is the urban dendroflora of the Macedonia Park, situated on about 50,000 m2 in the Macedonian capital city of Skopje, i.e., identification and presence of the recent woody plants. Thus, observed are morphological and ecological features of the woody plants and their current state in this urban environment. The investigation relates to a seven-year period (since the establishment of the Park in 2012 up to late 2019). After the field research and the inventorisation of the woody plants in the Park, 82 taxa were identified, represented in 1,318 individuals. Most represented tree species is the hybrid Platanus × hispanica Mill. ex Münchh. with 103 individuals (7.81% of the overall urban dendroflora). Most frequent tree including infraspecific taxa is Fraxinus excelsior L. (including F. e. ‘Globosa’, F. e. ‘Jaspidea’, and F. e. ‘Pendula’) with a total number of 146 individuals (11.08%). Concerning other growth form, the mini and small tree roses of hybrid Rosa Floribunda Group outnumber all ornamental woody species with 225 bushes (17.07%). Climbers are represented with 3 taxa (3.66% of identified taxa) in pergolas (Wisteria sinensis /Sims/ Sweet, Parthenocissus quinquefolia /L./ Planch.), and wire cage topiary (Hedera helix L.). Likewise, 87 individuals (6.60%) of 10 species (12.19%) occur as remnants of the greening in the past of which 3 species are used as a green core of a small sacral architecture: Cupressus sempervirens var. horizontalis (Mill.) Loudon (with 10 trees), Platycladus orientalis (L.) Franco (3), and Pinus nigra J.F.Arnold (1). In general, the urban dendroflora is properly selected and used for greening, although certain species and individuals are withering (e.g. Betula pendula ‘Youngii’, Juniperus scopulorum ‘Skyrocket’, F. e. ‘Jaspidea’) or unsuitably used for avenue and in small alpine-like garden.

Forcing plant material has long been used to determine dormancy intensity (DI) in woody species. Forcing with growth regulators may enhance this ability. Some forcing with naturally occurring hormones may be showing us the actual DI of certain materials. But, measurements of DI that use caustic, near-lethal treatments, or metabolic agents may be all or nothing breaking indicators acting on mechanisms other than the dormancy mechanism and thus not as useful in determining DI. It is possible to cause a meristem to break without completely breaking dormancy. Measurement of normal post-dormancy growth is necessary to determine the effect of a DI agent. DI breaking treatments that act on the dormancy mechanism can cause a temporary growth flush, but, unless the extent of that growth flush is measured and compared with the growth flush of the same normally broken plant material, its true effect remains unknown. In some plant material, the safest way to determine DI is to determine the chilling required to produce normal growth. This assumes that the vernalization requirement and temperature response curves are known for the plant in question. In peach, for instance, vernalization at 2C will cause seeds to germinate, but the resulting seedlings will be physiologically dwarfed. Vernalization at 6C or at 2C cycled with higher temperatures within the vernalization range results in normal seedlings. This indicates that, for chilling to progress normally, vernalization per se must be interspersed or concomitant with growth heat units. Vernalization, therefore, has a low temperature driven component and a heat requiring development and/or growth component. Vernalization driving conditions are slowly being elucidated. Each clarification requires modification of dormancy models. DI does not equal dormancy status!
