“…From a physiological viewpoint, P. pinea is known to reduce photosynthesis when water stress occurs, a mechanism that has been observed in this species during summer and early autumn, and does not show any summer quiescence (Liphschitz et al, 1984;Awada et al, 2003;Teobaldelli et al, 2004). It can therefore be considered as a drought-tolerant Mediterranean species that continues its growth, albeit reduced, during the dry season (Specht, 1981;de Lillis and Fontanella, 1992).…”

Abstract:In order to assess the response of the radial growth of Pinus pinea L. to climatic variability in Central Italy, dendrochronological and dendroclimatological analyses were carried out on five different populations scattered along the Tyrrhenian coasts of the peninsula. The aim of this study is to contribute to the understanding of the ecological demands of this species, particularly in the study area. For each site total ring, early-, and late-wood width chronologies were developed. Multidimensional analyses were performed for the three tree-ring datasets in order to analyze the relations between sites chronologies. Both Principal Component Analyses and hierarchical classifications highlighted an important difference of one site in respect to the other, probably due to site characteristics. Correlation functions were performed to infer the main climatic factors controlling the radial growth of the species. For a comparative study, we limited our attention to the common interval 1926-2003 (78 years) in which the response of the tree-ring chronologies to climate at both local and regional scale was investigated. Positive moisture balance in the late spring-summer period of the year of growth is the climatic driver of P. pinea radial growth in the study area. Moreover, this study shows how low summer temperatures strongly favor the radial growth of the species.

“…During the spring-summer period (March to September of the year of growth), the cambium activity takes place (Liphschitz et al, 1984). Then, the tree is highly dependent upon the amount of water stored in the soil for the construction of the ring (Campelo et al, 2006).…”

“…Liphschitz et al [37,38] showed that the cambial activity in P. pinea growing in semiarid sites in Israel starts in the middle of February or March and continues until November, without growth intermission in summer. The positive effect of February (t) temperature in earlywood and tree-ring width in the coastal area represented an early interruption of winter dormancy, which means an extension of the growing season and therefore wider tree rings.…”

Climatic significance of tree-ring width and intra-annual density fluctuations in Pinus pinea from a dry Mediterranean area in Portugal

et al. 2007

-In Mediterranean climates trees may go through two periods of dormancy, resulting in special anatomical features such as false rings and other intra-annual density fluctuations (IADFs). In this paper, ring growth and the presence of IADFs were studied in Pinus pinea L. growing in the coastal and inland regions of Alentejo (southern Portugal). In order to identify the triggering factors associated with the IADFs, a new classification was proposed for the IADFs in P. pinea: Type E (latewoodlike cells within earlywood); Type E+ (transition cells between earlywood and latewood); Type L (earlywoodlike cells within latewood) and Type L+ (earlywoodlike cells between latewood and earlywood of the next tree ring). Response function analyses showed that radial growth of P. pinea was strongly correlated with precipitation in southern Portugal. The climatic response of P. pinea was higher in the inland area where the summer drought is more severe, the winter temperatures are lower and the soils have low water-holding capacity, in comparison with the coastal area. IADFs were frequent in P. pinea and most of the IADFs were observed in latewood. The presence of IADFs was correlated with fluctuations in climate parameters during the growing season. The IADF type E+ was linked to precipitation events early in summer. The IADF type L and L+ were associated with above-average precipitation in early autumn.false tree-ring / Mediterranean climate / Pinus pinea / radial growth / wood anatomy Résumé -Signification climatique de la largeur des cernes et des fluctuations intra annuelles de la densité chez Pinus pinea dans une région méditerranéenne sèche du Portugal. Dans les climats méditerranéens, les arbres peuvent traverser deux périodes de dormance, ce qui a pour consé-quence des caractéristiques anatomiques particulières telles que des faux cernes et des fluctuations intra annuelles de densité (IADFs). Dans cet article, la croissance des cernes et la présence de IADFs ont été étudiées chez Pinus pinea L. poussant dans les régions côtières et intérieures de l'Alentejo (sud-ouest du Portugal). Dans le but d'identifier les facteurs déclenchants associés à l'IADFs, une nouvelle classification a été proposée pour l'IADFs chez Pinus pinea : Type E (cellules ressemblant à du bois final dans le bois initial) ; Type E+ (cellules de transition entre bois initial et bois final) ; Type L (cellules ressemblant à du bois initial dans du bois final) et Type L+ (cellules ressemblant à du bois initial entre bois final et bois initial du prochain cerne). Les analyses des fonctions de réponse ont montré que la croissance radiale de Pinus pinea était fortement corrélée avec les précipita-tions dans le sud-ouest du Portugal. La réponse climatique de Pinus pinea a été plus forte dans la zone intérieure où la sécheresse d'été est plus sévère, les températures hivernales plus basses et où les sols ont une plus faible capacité de rétention de l'eau, comparativement aux zones côtières. IADFs a été fréquent chez Pinus pinea et la majorité d'IADFs ...

“…This result suggests that growth in this species is less limited by warming induced drought stress during summer as compared to P. halepensis. This ability might be related to physiological-age interactions as P. pinea is characterised by high capacity to store water which minimizes water stress during summer, it reduces photosynthesis when water stress occurs and its high hydraulic conductivity enables the efficient use of underground waters (Liphschitz et al, 1984;Oliveras et al, 2003;Teobaldelli et al, 2004;Campelo et al, 2006). P. pinea trees in the study area are older than those of P. halepensis and such trees are less sensitive to drought conditions as opposed to the young trees (Carrer and Urbinati, 2004;de Luis et al, 2009;Olivar et al, 2012).…”

Abstract:In this study are presented chronologies of earlywood (EW), latewood (LW) and tree-ring widths (RW) of a Pinus halepensis (P. halepensis) and Pinus pinea (P. pinea) natural forest stand growing in western Albania. Bootstrapped correlations and pointer year analysis were combined in a dendroclimatological study to evaluate climate-growth relationships in both pine species as well as to assess the spatial outreach of our chronologies evaluating them with those of the same species from other Mediterranean countries. We found that both species responded positively to precipitation and Indexed Percentage Average Precipitation (%AvP) in late summer-early autumn, particularly the LW, whereas summer temperatures constrained the growth of P. halepensis tree-ring features. Current January temperature and Potential Evapotranspiration (PET) showed positive relationship with P. pinea LW and RW. The same association was observed when considering PET in spring and P. halepensis LW and RW. Pointer year analysis showed that inhibitory climatic drivers of radial growth for both species were low precipitation from previous winter and current summer, associated with low temperatures during autumn. Our P. halepensis chronology showed a wider spatial outreach than that of P. pinea when compared to those from other Mediterranean countries. We conclude that current January temperatures and September precipitation are very important for P. pinea growth influencing both EW and LW growth whereas P. halepensis is mostly affected by the summer-early autumn climate conditions.
