“…The cascade and coastal provenances were also found to have superior productivity across a wide range of planting conditions and are expected to be the most productive in climate change across many regions in Europe (Chakraborty et al 2015;Chakraborty et al 2016). Genetic variation in frost damage and resistance have been studied extensively in North America (Emerson et al 2006;St Clair 2006;Bansal et al 2015) but rarely in Europe (but see; Lavadinović et al 2013;Malmqvist et al 2017). Phenology plays an important role in genetic variation in frost tolerance in temperate plants (Cooper et al 2019).…”

“…Phenology plays an important role in genetic variation in frost tolerance in temperate plants (Cooper et al 2019). Interior provenances are likely to have less resistance against late frost in spring because they flush earlier than coastal provenances (St Clair 2006;Wolf 2012;Lavadinović et al 2013;Bansal et al 2015;Malmqvist et al 2017). Coastal provenances, however, may exhibit higher sensitivity to early frost events in autumn because they need longer time for bud set and hardening (Aitken et al 1996;Lavadinović et al 2013;Malmqvist et al 2017).…”

We, however, did not find any evidence to this difference in spring and autumn frost sensitivity among Douglasfir provenances in our study, probably, because both early and late frost events play an equally important role in our regions.…”

& Key message Autumn and spring frost events caused wide variation in the survival of juvenile Douglas-fir in Austrian forest sites located in the transition zone from Atlantic to continental climate. Survival rate can be optimized by planting provenances originating from an altitudinal belt of 500-1400 m in North America. Neither the variety nor the climate of origin of planted Douglas-fir provenances influence its response to frost events. & Context Understanding the risks of frost during late spring and early autumn is crucial for planting non-native Douglas-fir (Pseudotsuga menziesii [Mirbel] Franco) as an alternative tree species under climate change in Europe. & Aims We investigate the role of early and late frost events on the survival of juvenile Douglas-fir and tested whether survival depends on seed origin. & Methods With data from 19 provenance trials across Austria, we modeled the effects of early and late frost events on juvenile survival rate, accounting for random variations due to site condition and provenance origin. & Results Wide variations (37-93%) in the juvenile survival rate of Douglas-fir were mainly driven by early and late frost events (daily T min < 0°C), summer drought, and continentality. Juvenile survival declined with an increasing number of frost events within the observation period and prevailing warm spells preceding the frost events. The seed origin of the tested provenances had a minor effect and was related to the altitude, but not to the variety or the climate of provenance origin. & Conclusion For planting Douglas-fir in the transition zone from Atlantic to continental climates, typical in Austrian forests, the local site conditions and the probability of the occurrence of early and late frosts should be considered, while provenance selection should rather focus on productivity.

“…The introduction of a species involves adaptation, productivity and reproduction success in new environmental conditions. An introduction also requires to ensure that the species related are superior at their natural habitat (Lavadinović et al, 2013). Good knowledge of soil properties is crucial for the successful introduction of woody plants not only into the Arboretum Mlyňany but also to other parks and ornamental zones.…”

Successful adaptation of introduced trees requires providing appropriate conditions for their growth and life. In this context, our study aim was a soil survey in the Arboretum Mlyňany, on the basis of which the soils could be classified. Detailed soil investigations were done at seventeen sites under dense monocultures of trees and the grassland. For each site, there was dug one soil pit, near which there were made three soil bores. Over most area of the locality, the prevailing soil-forming substrates were decalcified loess and silt, with gravelly patches, with prevailing medium soil texture, and acid to slightly acid pH. Based on the morphological features and the results concerning the physical and chemical soil properties, seven quality-degrees of soil cover were classified. The lowest-quality was recognised in Fragic Stagnic Retisol, in the highest-situated, east part of Arboretum, and also in the central part of the Ambrozy’s park under Thuja plicata, where there was discerned also low quality Albic Stagnic Luvisol. The most area east of the manor house is covered with Stagnic Cutanic Luvisol (the North American and East Asian area with Stagnic Cutanic Luvisol (Anthric)). North of the manor, on a slight slope of the North American area was found a Cutanic Luvisol (Anthric). West of the manor, the terrain evenly declines, and there has been developed Luvic Chernozem, whose cultivated form, Luvic Chernozem (Anthric), was determined in the East Asian area.

Abstract:The aim of the article was to study the growth of Douglas-fir plantations in the region of the Training Experimental Forest Enterprise, Yundola (Central South Bulgaria). The study sites were three Douglas-fir plantations, ranging between 50 and 55 years of age at altitudinal range between 1,400 m and 1,600 m above sea level (masl). The mean height, diameter at breast height, site class, stem volume as well as the mechanical resistance (H/D ratio) of Douglas-fir were measured for each plantation. The results showed that Douglas-fir had the best height growth of the studied plantations on slope facing South at altitude 1,600 masl and Douglas-fir with age 55 years old reached a mean height of 32.4 m. The average diameter at breast height of the studied plantations reaches approximately 30 cm, which shows that they are suitable for large scale wood harvesting. The average stem volume of Douglas-fir in the observed plantations up to age of 55 is within the range of 400-600 m 3 /ha, with an average annual volume increment from 7 m 3 /ha to 12 m 3 /ha each year. The high index of mechanical resistance (H/D ratio) indicated a risk for abiotic damages, which implicated the need for the immediate implementation of felling.
