Variation of the Almond Leaved Pear (Pyrus spinosa Forssk.) in Croatia according to the morphology of leaves

The variation of 5 Almond Leaved Pear (Pyrus spinosa Forssk.) populations in Croatia (Biokovo, Blato na Cetini, Istria, Muć and Vir) was studied. The intra- and interpopulational variation was estimated according to 9 morphological traits of the leaves and 3 derived ratios. The descriptive and multivariate statistical methods were applied. High variation of the morphological traits of the leaves was found, and the variability coefficients in all populations were ranging between 10, 56 % for the ratio of leaf blade length measured from the base to the widest point of the blade and leaf blade length up to 47, 15 % for the leaf blade surface. The variation within populations was greater than among them for most of the examined traits. By applying the multivariate method a differentiation of the northernmost population in Istria from the other 4 Dalmatian populations was found, which is especially observable in relation to the southernmost population on Biokovo.
