“…Hejnowicz and Romberger (1973) showed that in ash for example, the waves were not apparent before 10 years. This was recently confirmed by Sopushynskyy and Teischinger (2013). Such a wavy grain formation can be observed in a minor number of trees within a population in almost all deciduous trees.…”

Over the last 15 years, shoot material from wavy grain sycamore maples (Acer pseudoplatanus L.) was collected from crowns of trees which were harvested and the stems then sold for very high values. Starting with grafts from this material, cutting propagation was tested and a tissue culture method was elaborated. However, the question of whether the wavy grain structure is expressed after vegetative propagation still remained unsolved. Recently, one of the oldest cuttings (11 years) and two grafts (17 years) were cut to look for structures of wavy grain expression. Veneer was produced from the log of the cutting-derived tree. Staining experiments were carried out using veneer sheets to improve the appearance of the structures. Based on these experiments, and in using morphological comparisons with veneer from adult wavy grain sycamore, we present the first evidence for the appearance of undulating fibre structures and the beginnings of wavy grain formation even in material at around ten years of age. A hypothesis related to the formation of wavy grain in deciduous trees is discussed.

“…Green ash has an air dry density of 702 kg/m 3 , it is almost 10% higher than those mentioned by Meier (2015), while having nearly the same basic density. The test results correspond to the density of the common ash (Wagenführ 2007, Sopushynskyy and Teischinger 2013, Meier 2015, Diler 2017, Giagli et al 2018, making the wood characteristics very similar.…”

“…Analysing the investigations of domestic and foreign researchers, we established that the most important factors contributing to the successful growth and distribution of stands with ash trees in the composition are soil and hydrological conditions. As a rule, ash stands grow in lower relief areas on fresh and moist mineral-rich and well-drained soils (Marigo et al, 2000;Dobrowolska et al, 2011;Sopushynskyy, 2012). River floodplains also create favorable conditions for the regeneration of common ash (Dufour & Piegay, 2008).…”

The natural distribution area of common ash (Fraxinus excelsior L.) in the forests of Europe and Ukraine has been determined through the analysis of scientific works of Ukrainian and foreign researchers. According to the reference materials on the current state of Ukrainian forests (25 administrative regions), it is established that ash forests cover an area of about 150,000 ha or 2.4% of the total area of the country’s forests. Among them, common ash stands account for almost 87% or 130,000 ha; the rest are stands of introduced ash species, namely F. pennsylvanica Marsh., F. americana L., and F. lanceolata Borkh. The average age of ash stands is 59 years. Only 6.4% (8,300 ha) of the total area of ash forests is covered by pure ash stands, and the remaining area (93.6% or 121,700 ha) are mixed ones. It is revealed that the optimal natural and climatic conditions for the emergence, preservation and successful growth of natural regeneration of ash trees are fresh and moist fertile sites (rich in minerals) with well-drained soils, the light of at least 5–6% of that on an open space, and without abundant live ground cover. The highest number of seed regeneration of ash, about 7,000–8,000 stems ha−1 on average, was found under the canopy of mixed (ash share in the composition was 10 to 20% by stock) old (over 100 years old) stands with a relative density of stocking of 0.7–0.8. Promoting the natural seed regeneration of ash trees can be an effective way of increasing the sustainability of such stands and will ensure their preservation in the forests of Ukraine and in deciduous forests of Europe as a whole.
