Variability of Pinus uncinata Ramond ex DC. as expressed in needle traits
Dendrobiology 2000, vol. 45: 07-16
Abstract: Two-year needles were collected from 42 trees from 5 localities in Spanish Pyrenees. The needles were analysed in respect to 15 morphological and anatomical traits. Data obtained were subject of multivariate statistical analyses. The most stable traits appear to be width of epidermis cells, width and thickness of the needles and ratio of the last two characters. Number of the resin canals and the vascular bundles distance were the most variable characters. The differences among the 42 investigated trees are not evident, considerably small and not significant statistically.
Additional key words: pine, Spain, morphoanatomy, statistical analysis.
