“…In general, the ratio between diameter fluctuations of the rigid xylem and the respective fluctuations of the elastic bark is typically known to be small (Zweifel and Häsler 2000;Steppe et al 2012). Améglio et al (2001a) found xylem to represent 15 % of the total shrinkage observed during freezing in stem segments of J. regia of 1 cm in diameter.…”

“…Decreased osmotic potential balances the decrease in water potential and lowers the equilibrium ice nucleation temperature of the cell sap (Taiz and Zeiger 2006). Dehydration of the elastic living tissue embedded in the xylem and living bark has been measured by monitoring diameter changes during freezing stress (Zweifel and Häsler 2000;Améglio et al 2001aAméglio et al , 2003a.…”

& Key messageWe assessed tree frost tolerance using electrolyte leakage and a method based on irreversible diameter change of branches. It was shown that irreversible diameter change correlates with electrolyte leakage and USDA hardiness rating and is a good indicator of frost tolerance. & Context The number of potential tree species for urban green planning is low in northern latitudes where cold tolerance is a critical factor. High cost of urban tree establishment calls for reliable and preferably non-destructive methods for determining their cold tolerance. & Aims We studied the cellular damage occurring during freezing and thawing in branches of seven broadleaved tree species using electrolyte leakage and a method based on branch diameter changes.& Methods Cellular damage in branches was studied during the cold-hardy stage in winter and the dehardening stage in early spring in laboratory conditions using both monitoring of frost-induced diameter changes and the common electrolyte leakage method during temperature decrease to −25°C. & Results Frost-induced irreversible diameter shrinkage correlated positively with electrolyte leakage. Out of the seven studied species, Quercus palustris and Crataegus monogyna had the highest frost tolerance during the dehardening stage in early spring, whereas Pterocarya fraxinifolia was the least frost tolerant. & Conclusion Irreversible shrinkage of branch diameter due to freezing stress is a good and non-destructive method to indicate frost tolerance. It also correlates well with the USDA plant hardiness rating that is based on the minimum temperature range in which the studied species prevail in the USA.

“…Generally, the mean air temperature is above 0 • C, and the minimum air temperature is below 0 • C. The extracellular liquid will be frozen when the air temperature falls below 0 • C [49]. Thus, the water potential of the extracellular space will be lower than the intracellular, cytosol water will be withdrawn from the living cells by permeation, and this process will lead to the reduction in the cell volume, which makes the contraction phase happen [33,50]. The frozen liquid will thaw when the air temperature rises above 0 • C, in which case the water will enter the living cells again, make the cell volume swell rapidly, and this process ultimately results in an expansion of the stem radius [33].…”

Picea crassifolia Komarov (Qinghai spruce) is an endemic tree species in China and is widespread in the Qilian Mountains, in northwestern China. High temporal resolution changes of Qinghai spruce tree stem growth remain poorly investigated and the relationships between the species growth and climate are still not completely understood. In this study, we assessed the daily and seasonal stem radial variations, and analyzed the relationships between stem radial increment of Qinghai spruce and environmental factors during the main growing period (June-August). We have found that the stem radial variations of Qinghai spruce can be divided into three phases according to the air temperature and that Qinghai spruce has two diurnal cycle patterns. The main growing period of Qinghai spruce is 30 May-31 August according to micro-core measurements, in conformity with the daily mean air temperature keeping above 5 • C. Precipitation and relative humidity have positive effects on the growth of Qinghai spruce, and we develop a multiple linear regression model that can explain 63% of the stem radial increment over the main growing period.

“…These dendrobands have been prominent in different studies, such as investigating tree water status [22], drought effects [14] or ozone and climate effects on tree growth [25]. An alternative to bands are point dendrometers to monitor the radial movements of tree stems [5,16,41]. Point dendrometers are usually mounted on stainless steel rods that are inserted into the wood.…”

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
