We analyzed genetic variability and phenotypic plasticity of flowering
pattern and reproductive success in 97 clonal genotypes of Iris
variegata originating from contrasting light habitats in Deliblato Sands
and expressed under different experimental light conditions. Rhizome
segments were taken from each of these clones and transplanted in the
experimental garden near the Institute for Biological Research in
Belgrade. Significant differences between genotypes were found for two
traits (start of flowering, average flowering time). Genotypes
originating from open and understory habitats significantly differed for
three traits (number of flowers, number of capsules/number of flowers,
seed mass/capsule). Significant effect of light treatment were found for
three traits (number of capsules/number of flowers, seed mass/capsule,
average seed mass). Statistically significant correlations between
explored traits were generally similar but also to some extent habitat
and treatment specific. Comparing these results with research carried
out on congeneric species we noted that there are similar responses for
some traits, but also significant differences in some components of
flowering and fruiting success.
