Wood formation dynamics of pine and birch along a south-north transect in Finnish Lapland were determined by the pinning technique. For all trees at all sites a more or less sigmoid shape of the wood formation intensity is characteristic with a slow beginning, a faster growth in the middle and a decreasing activity towards the end of the vegetation period. Wood formation of pine started at sites 1–3 (southern sites) in the second week of June and at sites 4 and 5 (northern sites) only in the last week of June, whereas wood formation ended within the first half of August. Wood formation of birch started in the second half of June and ended around the beginning of August. First cells were laid down by pine and birch when the temperature sum had reached the level of 85 to 90 degree days and 110 to 120 degree days, respectively. The intensity of wood formation in pine was highest in July, in birch within two weeks in the middle of July. Wood formation in pine lasted for about seven weeks at the southernmost and about six weeks at the northernmost site. In birch, the duration of wood formation was about five weeks at the southernmost site and around three weeks at the other sites.

Dendrometer and intra-annual tree growth: What kind of information can be inferred? (2007, methodology): “Therefore, other techniques, such as micro-sampling (Deslauriers et al., 2003a) or pinning (Schmitt et al., 2004), have to be used to identify the onset of radial growth.”
Cambial sensitivity to rising temperatures by natural condition and artificial heating from late winter to early spring in the evergreen conifer Cryptomeria japonica (2010, background): “The onset of cambial activity is strongly influenced by the environment (Denne and Dodd 1981; Schweingruber 1988) and it has been proposed that the maximum growth rate of trees might be regulated by temperature (Mäkinen et al. 2003; Rossi et al. 2007; Schmitt et al. 2004).”
Climate change and the regulation of wood formation in trees by temperature (2018, background): “The transition from rest to quiescence involves structural, histochemical and functional changes in cambial cells (Lachaud et al. 1999; Schmitt et al. 2004; Funada et al. 2016).”
Tree-ring variation, wood formation and phenology of beech (Fagus sylvatica) from a representative site in Slovenia, SE Central Europe (2008, unknown): “Numerous similar studies on various conifers from the temperate climatic zone have shown that cambial activity stopped at the latest by the end of August (e.g. Antonova and Stasova 1993; Horacek et al. 1999; Schmitt et al. 2004; Rossi et al. 2006b; Gričar 2007).”
