Abstract
In light of the increasing need for appropriate, cost-effective detection
methods of anthropogenic pollution, we evaluated the biomonitoring potential
of flower developmental instability (DI) on a widely planted decorative
species, Iris germanica, under in situ conditions. DI was measured by
fluctuating and radial asymmetries of parts of Iris germanica perianth (810
fall lengths and widths), from clones already growing in two distinct types
of habitats with contrasting levels of anthropogenic pollution: in unpolluted
(rural) areas, Novi Banovci, Stari Banovci and Belegis (flowers from 137
clones sampled), and in a polluted (urban) Belgrade metropolitan area
(flowers from 133 clones sampled). Our results revealed significantly higher
flower radial asymmetry in the polluted habitats compared to unpolluted ones
(for three out of four univariate indices, as well as both multivariate
ones), but failed to detect a similar effect on fluctuating asymmetry
indices. The results of our study therefore demonstrate the potential of DI
(when estimated by flower radial asymmetry) in Iris germanica as a
cost-effective biomonitoring method for in situ pollution detection based on
readily measurable flower parts and moderate sample sizes.
