“…In contrast, in years when precipitation was abnormally low and temperatures were higher than usual, most trees formed narrow rings. Our findings are in line with recent detailed intra-annual studies of P. sylvestris tree-ring formation Oberhuber and Gruber 2010;Eilmann et al 2011), which confirmed previous conclusions (Antonova et al 1995;Rigling et al 2001; Eilmann et al Thabeet et al 2009) that drought stress hinders cell production in P. sylvestris and thus may have profound effects on tree-ring width. The effect of moisture deficiency on tree-ring width in our study sites was most pronounced during several known drought periods-namely in 1917-1919, 1945-1948 and 1984-1994.…”

“…A possible explanation for the high frequencies of NLRs in dry years is that moisture deficiency in the period when latewood cells were forming and lignification was being completed, seriously affected these processes. Water shortage and stress are known to strongly influence cell metabolism and division and thus have an impact on tree-ring formation (Whitmore and Zahner 1967;Antonova et al 1995). In analogy with studies of tree-ring formation in coniferous species at sites with similar ecological conditions, we expect that latewood cell production at our sites starts in July, and cell wall thickening and lignification continues into October (Gindl et al 2001;Camarero et al 1998;Rigling et al 2001;Eilmann et al 2011), but may be terminated earlier due to dry conditions (Thabeet et al 2009;Gruber et al 2010;Eilmann et al 2011).…”

“…In order to injure the newly formed tracheids, these frost events must have happened after the start of cambial activity (Glerum and Farrar 1966;Hantemirov et al 2004). We did not study the onset of cambial activity in detail, but in analogy with other studies we expect it to start after the middle of April at xeric sites (Antonova et al 1995;Gruber et al 2010;Eilmann et al 2011) and at the beginning of May at high altitude sites (Rossi et al 2003(Rossi et al , 2008Gruber et al 2009). This is why we consider that frost events recorded at the beginning of May at lower altitude sites or in the middle of May at higher altitudes could have damaged cambial cells and newly formed tracheids.…”

“…Scots pine (Pinus sylvestris L.) is one of these species and is wide spread world-wide and in specific regions (Richardson 2000). In addition to this, numerous studies are available on P. sylvestris tree-ring width, density and anatomy variation and their dependence on climate (Grudd et al 2002;Briffa et al 2004;Antonova et al 1995;Rigling et al 2001;Eilmann et al 2006;Büntgen et al 2010;Oberhuber and Gruber 2010;Gruber et al 2010;Eilmann et al 2011). Yet, these studies were generally focused on specific sites or factors and thus, do not provide sufficient evidence of how tree-ring features could be indicative of different extremes dependent on the location.…”

Tree-ring studies may help better understand climate variability and extreme climate event frequency and are especially useful in regions where detailed meteorological records lack. We studied the effect of droughts and unusually cold periods on Pinus sylvestris tree-ring width and wood anatomy. Study sites were selected along an altitudinal gradient on Vitosha Mountain, Bulgaria. Drought conditions caused the formation of narrow tree rings or light rings if the drought occurred in July-August at the lower altitude sites. In years with droughts in June and the first half of July, followed by precipitation in the middle of July, intra-annual density fluctuations (IADFs) were formed. Trees in the zone with optimal growth conditions produced fewer light rings and narrow rings in years with either strongest droughts or unusually cold summers. At the timberline zone, low summer temperature triggered narrow tree rings and light rings. Frost rings were formed when there was a drop in temperatures below the freezing point in the second half of May or at the beginning of June. Our findings show that studies of tree-ring anatomy may contribute to obtain further knowledge about extreme climatic events in the Balkan Peninsula and in other regions where meteorological data lack.

“…With this approach it was possible to monitor wood formation at a particular spot on a tree over two years. Other methods using periodic wounding or repeated cambium sampling have faced the problem of wound effects, which were avoided by moving the locations for sampling either downwards [1] or around the circumference [34].…”

High-resolution analysis of radial growth and wood density in Eucalyptus nitens, grown under different irrigation regimes

-Wood density is the most important determinant of wood quality and a critical factor in short rotation forestry. Daily radial growth of six-year-old Eucalyptus nitens trees were monitored on a two hectare plantation in south-eastern Tasmania using point dendrometers, under different irrigation regimes. At the end of the second growing season 12-mm cores were extracted from the trees and processed for high-resolution wood density using SilviScan-2. The dendrometer measurements were utilized to rescale wood density on a time axis. In general, lower density was formed early in the growing season, and higher wood density later. The irrigated-droughted trees showed an obvious relationship between wood density and soil water deficits with the density decreasing in response to water stress releases. The density decrease was accompanied by acceleration in daily increment. With the presented approach the annual level is no longer the basis of analysis. This opens new opportunities for genotype × environmental interaction studies of trees, which is of particular importance in clonal forestry.wood density / dendrometer / wood quality / irrigation / cambium Résumé -Analyse haute résolution de la croissance radiale et de la densité du bois d'Eucalyptus nitens, croissant sous divers régimes d'irrigation. La densité du bois est le plus important déterminant de la qualité du bois et un facteur critique pour la sylviculture en courte rotation. La croissance radiale journalière d'Eucalyptus nitens, âgé de 6 ans, a été suivie dans une plantation de 2 hectares dans le Sud-Est de la Tasmanie en utilisant des dendromètres à point, sous différents régimes d'irrigation. À la fin de la seconde saison de végétation, des carottes de 12 mm ont été prélevées sur les arbres et une mesure haute résolution de la densité du bois a été réalisée à l'aide d'un SilviScan-2. Les mesures à l'aide du dendromètre ont été utilisées pour recaler la densité du bois sur un axe de temps. En général, le bois ayant la densité la plus faible a été formé tôt dans la saison de végétation, et le bois de haute densité plus tardivement. Les arbres irrigués ou soumis à la sécheresse montraient une relation évidente entre la densité du bois et le déficit hydrique du sol avec une densité diminuant en réponse à une réduction du stress hydrique. La diminution de densité a été accompagnée par une accélération de l'accroissement journalier. Selon l'approche présentée, le niveau annuel ne sera plus la base de l'analyse. Ceci ouvre de nouvelles opportunités pour des études de l'interaction génotype × environnement sur des arbres, ce qui est d'une importance primordiale en foresterie clonale. densité du bois / dendromètre / qualité du bois / irrigation / cambium
