“…Tracheids in softwoods have a maximum length of 5 mm (Hacke 2015) and therefore there is not a problem with possible embolized conduits due to cutting. The high variability observed for RWC L at the bottom of the stem in the inner wood area for A. alba species was due to the presence of wetwood for some trees, which is a quite common feature for this species and which seems to be related to a disease (Bauch et al 1979;Shortle and Bauch 1986) and associated with acidic anaerobic bacteria (Streichan and Schink 1986).…”

Abstract• Key message Intensive measurements of basic specific gravity and relative water content of lumens show that within-stem variations strongly depend on species and cannot be summarised through the typical patterns Handling Editor: Jean-Michel LebanContribution of the co-authors Fleur Longuetaud: designed the experiment, run the data analysis and was the main writer.

The observations were compared with typical patterns of variations reported in the literature.• Methods Wood discs were sampled regularly along tree stems and X-rayed in their fresh and oven-dry states.• Results At breast height, BSG was found to clearly increase radially (pith to bark) for two species and to decrease for one species. For F. sylvatica and A. alba, the radial variations of BSG were rather U-shaped, with in particular inner wood areas showing respectively lower and higher BSG than the corresponding mature wood. RWC L increased generally from inner to outer area but wet sapwood was clearly distinguishable only for the coniferous species. Vertical variations of BSG and RWC L were strongly dependant on the species with usually non-linear patterns.• Conclusion The observed variations of BSG were only partially in agreement with the reported typical radial patterns. Despite the vertical variations, the mean BSG of a cross-section at breast height appeared to be a good estimator of the mean BSG of the whole stem (although the difference was statistically significant for coniferous species), whereas breast height measurement of RWC L was not representative of the whole stem.

“…Declining fir trees generally experience growth reductions and crown damage including needle loss and yellowing foliage (Bauch et al, 1979;Eckstein et al, 1983;Schweingruber et al, 1983;Bauch, 1986;Larsen, 1986;Innes, 1993;Torelli et al, 1999). Reduced wood formation often occurs prior to visual symptoms of crown decline (Torelli et al, 1986(Torelli et al, , 1999, which highlights the usefulness of tree rings to reconstruct past vitality of individual trees and to indicate mortality risk (cf.…”

“…In the wood of T. scleroxylon, no significant discoloration takes place during the ageing of the tissue, but tylosis formation Starts in the same zone (sample No. Bauch et al (1979) and Klein et al (1979) observed in the sapwood of Abies species up to 200% moisture content, equalling that of central wetwood portions, whereas only 50% moisture was present in the intermediate parts. Therefore, this zone may be considered äs a transformation zone towards heartwood (Shigo and Hillis 1973).…”

Alterations of wood characteristics in Abies alba Mill. due to "fir?dying" and considerations concerning its origin

Abstract: In the wood of trees of/l/'/cs^/ia Mill., which wore affected by "fir-dying", morphological and physiological alterations were exatnined in order to investigate the origin of the disease. In this conte.xt ahso the influence on the technological wood quality was considered.
