Morfometrijske karakteristike listova planinskog javora (Acer heldreichii Orph) u centralnoj Srbiji

Abstract

U radu su dati rezultati proučavanja taksonomskih karakteristika planinskog javora (Acer heldreichii Orph), na osnovu analize karakteristika listova uporedno-morfološkim metodom. Proučavanja su vršena na tri lokaliteta u centralnoj Srbiji: Goču, Jastrepcu i Rudniku. Sa svakog lokaliteta je odabrano po 30 normalno razvijenih stabala, a sa svakog stabla odabrano po 30 listova za analizu. Proučeno je 8 merenih i 15 izvedenih obeležja lista. Rezultati analize su statistički obrađeni uz upotrebu korelacione analize analize varijanse i klaster-analize. Utvrđeno je postojanje dva varijeteta var. heldreichii i var. macropterum. U okviru var. macropterum su izdvojene 4 forme: f. typicum, f. dissectum, f. equiloba i f. rotundiloba. Populacije su relativno homogene, a oba varijeteta se pojavljuju na sva tri lokaliteta u značajnom broju.

The taxonomic characteristics of Greek maple (Acer heldreichii Orph) were studied based on the analysis of leaf characteristics, by comparative-morphological method. The study was performed at three localities in central Serbia: Goč, Jastrebac and Rudnik. 30 normally developed trees were selected per each locality, and 30 leaves were selected from each tree for the analysis. The study includes 8 measured and 15 derived characteristics of leaves. The study results were statistically processed by correlation analysis, analysis of variance and cluster-analysis. It is concluded that there are two varieties, var. heldreichii and var. macropterum. Four forms are set aside in the variety macropterum: f. typicum f. dissectum, f. Equiloba and f. rotundiloba. The populations are relatively homogeneous, and both varieties occur at all three localities in significant numbers.
