Sažetak
The analysis of nineteen morphological and anatomical traits of the needles and the shoots of four pine species: Pinus nigra Arnold, P. sylvestris L., P. densiflora Sieb. et Zucc. and P. thunbergiana Franco was made. Discriminant analysis showed that on the basis of these nineteen traits the samples of Scots pine, European black pine, Japanese red pine and Japanese black pine can be compleately discriminated. European black pine and Scots pine samples are discriminated best by needle stelar region cross-section area, needle cross-section area and number of external resin canals. European black pine and Japanese red pine are discriminated best by stelar region cross-section area, number of external resin canals and needle cross-section area. European black pine and Japanese black pine are discriminated best by stelar region cross-section diameter, needle cross-section area and number of serrations along one needle margin on a 1 cm segment from the middle of the needle. The traits by which the Scots pine samples are discriminated best from the Japanese red pine samples are: needle cross-section area, stelar region cross-section diameter and stelar region cross-section area. The traits by which Scots pine is discriminated best from Japanes black pine are: needle cross-section area, stelar region cross-section area and stelar region cross-section diameter. Japanese red pine and Japanes black pine are discriminated best by number of medial resin canals, number of external resin canals and the largest number of hypodermal cell layers on the needle cross-section.
