The most frequently and successfully used tree-ring parameters for the study of temperature variations are ring width maximum latewood density (MXD). MXD is preferred over due to a more prominent association with temperature. In this we explore dendroclimate potential dendroanatomy based on first truly well replicated dataset. Twenty-nine mature living Pinus sylvestris trees were sampled in North-eastern Finland at cool moist boreal forest zone, close latitudinal tree line, where width, X-ray as blue intensity counterpart MXBI compared dendroanatomical parameters. Maximum radial cell wall thickness anatomical appeared be promising reconstruction. fact, these compare favorably derived from techniques MXBI, terms shared variation correlations across frequencies time. reasons results thought unprecedentedly high measurement resolution technique, which provide optimal – whereas have slightly lower BI even lower. While encouraging, further tests longer multigenerational chronologies required generally fully assess
