“…Wood density was not correlated with P 50 in Prunus species either (Cochard et al 2007(Cochard et al , 2008. However, Martinez-Meier et al (2008) observed a plastic response and sensitivity to the environmental stress by increasing mean and latewood density in Pseudotsuga menziesii trees surviving extreme droughts. Pleucadec and San Cipriano populations, from sub-humid climates, displayed higher wood density, which is in agreement with Bouffier et al (2003), who found higher wood density in ponderosa pine populations from the wetter origins.…”

The objectives of the study were to assess the phenotypic variation in the vulnerability to water stressinduced cavitation (estimated by P 50 , or the xylem water potential which causes a 50% loss of conductivity) and the trade-offs between P 50 and related hydraulic traits, i.e., stem specific conductivity (K s ), slope of the vulnerability curve (slope), wood density and branch size. Variability was examined for six Pinus pinaster populations covering the latitudinal range of the species and plasticity was tested through two provenance-progeny trial sites (xeric/mesic). As expected, the overall values of P 50 , K s and branch size decreased in the xeric site. Variation in P 50 and K s among populations was mainly the result of phenotypic plasticity, while wood density was genetically controlled and not affected by the environment. Stress conditions in the xeric site promoted a convergence in P 50 and K s as a result of the high phenotypic plasticity of the populations from mesic origins. In the mesic site, the ranking of populations for cavitation resistance and hydraulic capacity was consistent with the geographic location of the seed source. Higher resistance to cavitation was related to lower K s , branch size and slope, mainly at the population level, but also as a general trend across individuals. In a warmer and drier climate, there could be a potential selection of Pinus pinaster populations from mesic origins, which showed a great responsiveness and adjustment to drought conditions (similar or higher P 50 than the populations from dry origins), in addition to a high wood density and growth.

“…The information on the response of mature trees to past environmental conditions is stored in tree-rings and can be revealed using methods of dendrochronology. In France, Martinez-Meier et al (2008) found higher survival of Douglas-fir trees with tree-rings of higher wood density. Consequentially, Dalla-Salda et al (2009) and Dalla-Salda et al (2011) demonstrated genetic differences and a link between wood density, cavitation resistance, and growth performance of mature Douglas-fir clones under the severe panEuropean drought event of 2003.…”

To select suitable planting stock for reforestation under uncertain future climates, information about tolerances of genotypes to different climate conditions is necessary. One useful approach is to combine dendrochronological research with common garden experiments to quantify genotype by environment interactions observed over time. Here, we assess the response of Douglas-fir provenances planted in a common environment to climate variation over five decades using treering analysis and historic height data. A rare drought event that affected growth in the year of 1985 provided the opportunity to study how mature Douglas-fir provenances differ in resilience and resistance to drought conditions and whether there are trade-offs with long-term productivity. We found that overall growth performance of provenances originating from drier and colder environments within the coastal range was below average and correlated with interannual variation in temperature. Productive provenances originated primarily from moist and warm areas and their annual increments covaried strongly with summer precipitation and summer drought indices. Further, provenances with below average growth were able to recover more quickly from the drought event of 1985, but did not show stronger drought resistance than coastal sources. Our results provide evidence for tradeoffs between productivity and drought resilience and show that sources originating from moist locations are more dependent on favorable growing conditions in the summer. We conclude that selecting drought-resilient planting stock as an adaptation strategy for climate change is possible, but it would entail reductions in productivity.

“…Phenotypic plasticity in wood (dendroplasticity) is a fundamental mechanism for the adaptability of tree species to changing environmental conditions (e.g. Martinez-Meier et al, 2008. Its measurement in relation to the climatic conditions of the study sites will determine whether E. grandis is actually more plastic than E. viminalis and E. globulus, or if the environmental conditions where individuals grew had a greater range of variation, which resulted in a greater variability of wood characters.…”

Aim of the study: To characterize wood anatomical traits of three Eucalyptus species that differ in wood density and ecological requirements, and to examine the relationships between some anatomical features, wood density, and theoretical xylem hydraulic conductivity (Ks).Area of study: We analyzed 86 trees from three sites of Argentina (Entre Ríos and Buenos Aires Provinces). Methods:The sampled trees were Eucalyptus globulus, E. grandis and E. viminalis ranging from 11 to 15 years old. One stem disc was cut from each tree to determine wood density and identify quantitative anatomical features of vessels and fibers. Vessel composition (S, size -to-number ratio, a measure of vessel size distribution) and lumen fraction (F, the total sapwood area available for water transport) were estimated.Results: E. grandis, the species with the highest growth rates, presented the highest theoretical Ks. This was associated with anatomical features such as a high density of wide vessels resulting in high F. On the other hand, E. viminalis, the species with the lowest growth rates and highest resistance to environmental stress, showed lower Ks as a result of a low density of wide vessels. These two species differed not only greatly in wood density but also in fiber characteristics. In the case of E. globulus, vessels were relatively narrow, which resulted in the lowest theoretical Ks, fibers were small, and wood density intermediate.Research highlights: F had greater influence on Ks than S. The anatomical characteristics and wood density could only partly explain the differential growth or resistance to stress of the studied species.
