Dendroécologie du Pin Sylvestre de Mazovie, Pologne : influence de l'antécédent cultural sur la macrostructure du bois et la réponse au climat

Abstract : Poland continues to be afforested its poorest agricultural land, even if the soil conditions are deemed worse than those of forest plantations. Thus, does the previous land-use (i.e. agriculture versus forest) modifies xylogenesis and sensitivity to climate? Investigations were conducted in Polish lowland, on 40 Scots pines from 65 to 101 years old. Ring-width series of double radii were created based on measurement of annual rings using WinDENDRO. Dendrochronology technics (i.e. crossdating and double standardization) allowed obtain a master chronology, which was confronted with climate data through correlation functions and an analysis of pointer years. These results showed that a mild winter and additionally a cool and wet autumn were the main factor for a large Scots pine ring. Comparative analysis highlighted that pines from former farmland (i) grown more slowly (-16%) than pines grown under forest typical conditions and (ii) showed increased sensitivity to climatic factors, both in normal years and in extreme conditions. A contrario, pines from former farmland from 5 to 35 years-old, experienced a higher latewood proportion, for a core of juvenile wood of only 6 cm on average.
