摘要：The objective of this study is to compare yearly variability of the tree ring parameters of coniferous species (spruce, fir, Scots pine and larch) in the north-eastern part of the Eastern Carpathians (Romania). The microcores were collected at the end of the vegetation season in 2012. Micro-sections were prepared in order to analyses the tree-rings characteristics for the last three vegetation seasons. To emphasize the influence of species and interannual climate variation on tree growth, the following parameters were used: total tree ring width, number of tracheids and mean tracheids dimension. All the species showed different dynamics of the tracheids number, as well as of the tree-ring width in the three studied vegetation seasons. The highest growth in term of cells number was observed in Picea abies, whereas a reduced cells number but with higher dimensions was observed in Larix decidua. The variability of radial growth of the xylem in relation with the climate was discussed for each species separately.
