The aim of this work was to compare the length, width, centroid size and shape (using a set of shape variables - partal warps) of Iris pumila standards (petals) from an urban area of Belgrade city with data from the Deliblato Sands – an unpolluted nature reserve. Differences between the areas, as well as differences in clonal variability, for length, centroid size (ANOVA p < 0.001) and shape variation of standards were significant (MANOVA p < 0.001). Micro-environmental conditions induced significant diversity between flowers within a clone (p < 0.001), while intra-individual variation (part effects, p > 0.05) was not confirmed. Decrease of standard length and centroid size in the polluted environment was detected, as well as a change in the shape of this I. pumila flower part. The standards were shorter and wider in the polluted area when compared to those in the unpolluted environment. |
