White spruce breeding has traditionally focused on genetic improvement for high productivity, targeting mostly stem volume. However, new challenges, such as the effects of climate change on individual trees and ecosystems and the changing nature of forest products markets, require action to address these issues while providing improved stock for seed and seedling production. This work aims to define the relative importance of white spruce wood traits for the lumber industry, with the intent of guiding tree breeding programs. This manuscript examines: (1) wood features that are important for lumber, (2) the genetics of wood traits and their improvement and (3) the level of acceptance of raw material with optimal traits, as obtained from a survey conducted with sawmills. Stem diameter at stump height, wood density, bending strength and stiffness were determined as the most important properties for sawmills. Decay proportion, knot diameter, slope of grain and the proportion of compression wood were also determined as important for sawmills, but to a lesser extent. Breeding efforts aiming to produce lumber should focus on stems with improved growth that are capable of sustaining the production of dense wood in greater proportion.

“…4). It must also be mentioned that according to the methodology of estimating density separately for earlywood and latewood it did not reflect the typical negative correlation to increased secondary growth induced by higher temperatures as found in other studies ( Cortini et al, 2016 ; Hassegawa et al, 2019 ). DEN showed similar but overall relatively weaker reactions to climate conditions than CWT.…”

Direct and Indirect Effects of Environmental Limitations on White Spruce Xylem Anatomy at Treeline

et al. 2021

Treeline ecosystems are of great scientific interest to study the effects of limiting environmental conditions on tree growth. However, tree growth is multidimensional, with complex interactions between height and radial growth. In this study, we aimed to disentangle effects of height and climate on xylem anatomy of white spruce [Picea glauca (Moench) Voss] at three treeline sites in Alaska; i.e., one warm and drought-limited, and two cold, temperature-limited. To analyze general growth differences between trees from different sites, we used data on annual ring width, diameter at breast height (DBH), and tree height. A representative subset of the samples was used to investigate xylem anatomical traits. We then used linear mixed-effects models to estimate the effects of height and climatic variables on our study traits. Our study showed that xylem anatomical traits in white spruce can be directly and indirectly controlled by environmental conditions: hydraulic-related traits seem to be mainly influenced by tree height, especially in the earlywood. Thus, they are indirectly driven by environmental conditions, through the environment’s effects on tree height. Traits related to mechanical support show a direct response to environmental conditions, mainly temperature, especially in the latewood. These results highlight the importance of assessing tree growth in a multidimensional way by considering both direct and indirect effects of environmental forcing to better understand the complexity of tree growth responses to the environment.

“…Intracoenotic factors connected with intra-and interspecific competition between trees are also important resulting in the differentiation of individuals in terms of growth rate and vitality status (Demidko et al 2010;Das 2012;Hereş et al 2018). Several authors found a significant correlation between stem radial growth and main indicators of vitality status of conifer trees such as crown density (Demidko 2011;Cortini et al 2016;Donnelly et al 2017) and needle mass (Vanninen 2004). Using Pinus sibirica Du Tour as an example, Demidko et al (2010) showed that the radial increment in strongly weakened individuals at the age of 60 and 140 years is 35% and 65% lower than in healthy ones.…”

The research was carried out in unmanaged middle-aged (75â85 years) Northern taiga Scots pine ( L.) forests in the Kola peninsula. It was established that forests of green moss-lichen and green moss site types are characterised by a predominance (65â70% by stand volume) of moderately and strongly weakened trees. Trees of differing vitality have significant differences in annual increment. Healthy trees had a radial increment (RI) 70â75% greater than that of dying trees, and a basal area increment (BAI) 85â90% greater. The dynamics of the RI and BAI of Scots pine trees for the 70-year period (from 1945 to 2015) is different. The RI of all individuals in the communities studied decreases consistently. The decrease is expressed more strongly in green moss Scots pine forests (80â95% from 1945 to 2015) compared to green moss-lichen forests (60â80%); it manifests itself more in strongly weakened and dying individuals (75â95%) than in healthy and moderately weakened ones (60â80%). Annual basal area increment in green moss Scots pine forests increases by 45â65% from stand establishment until the trees are 25 to 35 years old and subsequently decreases by 50â80% to 70â80 years of age. In green moss-lichen pine forests the BAI of Scots pine remains rather stable in healthy and moderately weakened trees and decreases in strongly weakened and dying individuals by 45% and 75â80%, respectively throughout the studied period.Pinus sylvestris
