“…Higher winter temperatures enhance respiration rates and thus can lead to the depletion of assimilates stored. As cambial resumption of ring‐porous oaks starts before bud break (Copini et al., ; Kudo et al., ; Pérez‐de‐Lis et al., ), and vessel functionality occurs just before the leaf expansion (Guada, García‐González, Pérez‐de‐Lis, Vázquez‐Ruiz, & Montserrat‐Martí, ; Kitin & Funada, ) the formation of EW vessels relies on the amount of stored carbohydrates from the previous growing season. A shortage of carbohydrates as an effect of high winter temperatures can therefore be associated with the formation of smaller vessels (González‐González, Vazquez‐Ruiz, & García‐González, ).…”

Aim Spatial variations of environmental conditions translate into biogeographical patterns of tree growth. This fact is used to identify the origin of timber by means of dendroprovenancing. Yet, dendroprovenancing attempts are commonly only based on ring‐width measurements, and largely neglect additional tree–ring variables. We explore the potential of using wood anatomy as a dendroprovenancing tool, and investigate whether it increases the precision of identifying the origin of oak wood. Since different tree–ring variables hold different information on environmental conditions prevailing at specific times of the growing season—which vary between source regions—we hypothesize that their inclusion allows more precise dendroprovenancing. Location Europe, Spain. Taxon Quercus robur L., Quercus petraea (Matt.) Liebl., Quercus faginea Lam., Quercus pyrenaica Willd. Methods We sampled four oak species across Northern Spain, i.e. from the Basque country and Cantabria and—in the Basque country—from low to high elevation (topographic/latitudinal gradient). We measured multiple tree–ring variables to (a) extract complementary variables; (b) present statistical relations among them; (c) analyse region‐specific variation in their patterns based on time–series of individual trees; and (d) determine underlying climate–growth relationships. Leave‐one‐out analysis was used to test whether a combination of selected variables allowed dendroprovenancing of a randomly selected tree within the area. Results A combination of latewood width (LW) and earlywood vessel size was used to pinpoint the origin of oak wood with higher precision than ring width or LW only. Variation in LW pinpointed the wood to east and west areas, whereas variation in vessels assigned wood to locations along a latitudinal/topographic gradient. The climatic triggers behind these gradients are respectively an east–west gradient in June–July temperature and a north–south gradient in winter/spring temperatures. The leave‐one‐out analyses supported the robustness of these results. Main conclusions Integration of multiple wood–xylem anatomical variables analysed with multivariate techniques leads to higher precision in the dendroprovenancing of ring‐porous oak species.

“…This was consistent with the results of Becker et al’s (2012) research on 23 angiosperm tree species ( Alstonia boonei et al) in East African rain forests, which found a significant proportional relationship between the specific gravity of wood and water storage. This may be partly due to the importance of water to plant physiological and biochemical reactions (Guada et al, 2018). In total, the two typical coniferous species had similar water storage distribution characteristics, which supported biomass accumulation (a proxy for productivity) at the individual tree level.…”

“…Different species in different ecosystems might have similar hydraulic mechanisms (Domec et al, 2010; Yu & D’Odorico, 2015). Because of the strong relationship between water storage and plant physiological processes (Guada et al, 2018), we hypothesized that the two conifers growing in contrasting climates would have similar water storage distribution characteristics, due to their similar growth habits, and such characteristics are closely related to growth and therefore biomass accumulation. Our study focused on Chinese fir and Korean larch, which are two conifers adapted to warm and moist, and cold and dry climates in China, respectively.…”

Background Water storage is a significant physiological index of vegetation growth. However, information on water storage at the individual tree level and its relationship to climatic conditions and productivity is scarce. Methods We performed a comparative analysis of water storage using field measurements acquired three age classes of Chinese fir (Cunninghamia lanceolata) and Korean larch (Larix olgensis). The distributions of water storage, water content ratio and dry mass were presented, and regression analyses were used to confirm the relationships of water storage and water content ratio to dry mass components, respectively. Results Our results indicated that water was mostly concentrated in the stem xylem, which aligned well with the distribution of dry mass in both conifer species. However, the water storage of the stem xylem was always higher in Chinese fir than in Korean larch. The average water content ratio of both conifer species decreased with age, but that of Chinese fir was always higher than that of Korean larch. There was a significant difference in the water storage proportion in the components of Chinese fir (P < 0.001) and Korean larch (P < 0.001). The effects of age class on the water storage of Chinese fir (P = 0.72) and Korean larch (P = 0.077) were not significant. Interestingly, significant positive linear correlations were found between fine root water and leaf water and mass in Chinese fir (P < 0.001, R2 ≥ 0.57) and Korean larch (P < 0.001, R2 ≥ 0.74). The slopes showing that the linear relationship between tree size and water content ratio of stem xylem were always steeper than that of other components for the two conifers. Conclusion Our study indicates the similar water related characteristics and their close relations to biomass accumulation and growth in both fast growing species at contrasting climates, illustrating the same coherent strategies of fast growing conifers in water utilization.

“…vessels or tracheids dimensions, and wood formation of conifers and broadleaves revealed new insights on tree ecology (e.g. Guada et al, 2016;Pérez-de-Lis et al, 2017;Guada et al, 2018) and tree physiology (Cuny et al, 2015;Steppe et al, 2015). Moreover, other xylem features were found to record either complementary information to tree-ring width (García-González & Fonti, 2006;Fonti et al, 2007;Fonti & García-González, 2008;Gea-Izquierdo et al, 2012) or to contain a stronger environmental signal than ring width (Wilson & Hopfmueller, 2001;Wilson et al, 2014).…”
