Tree rings result from the total number of woody cells formed under various positive and negative environmental influences prevailing prior to and during a growing season. That is why it is assumed that cell-anatomical variables such as lumen area or wall thickness may have ‘archived’ some environmental information. Most studies up to now were made with deciduous tree species such as oak and beech using their vessel sizes. Only recently, conifers have come into focus. It has been proven that cell-anatomical chronologies of conifers are useful climate proxies providing environmental information other than tree-ring width or density. However, the question of how many radial transects should be taken into account has not unequivocally been answered yet. Here we present an estimation of how many radial transects are necessary to establish reliable cell-anatomical chronologies using examples from three Scandinavia sites.
