o:3740 Morpho-anatomical traits of Pinus puece needles from natural populations in Montenegro and Serbia. en "Variability of eight morpho-anatomical traits of two-year-old needles of the Macedonian pine (Pinus peuce Griseb.), collected from natural populations of Montenegro (Zeletin and Sjekirica) and Serbia (Mokra Gora), was investigated. The needles have two resin ducts of the external type (touching epidermis). The average values were as follows: 7.14 cm (needle length), 0.86 mm (needle width), 0.66 mm (needle thickness), 13.32 µm (cuticle+epidermis thickness), 16.24 µm (height of hypodermal cells), 1.45 (number of hypodermis layers), 2 (number of resin ducts) and 52.45 µm (resin duct diameter). The most variable characters were needle width and needle thickness. PCA visualizes overlapping of three populations. Cluster analysis suggests that the Sjekirica population is more similar to the Mokra Gora population than to the geographically nearest population of Zeletin. Given results are discussed in relation to our previous investigations of this species based on terpenes and n-alkanes, where the population from Mt. Zeletin also exhibited differences compared to the population from other Balkan localities.
