Plants as sessile organisms have to continuously adjust their growth, development and reproduction to
variable surroundings, especially in relation to light as an essential abiotic factor. Plants growing in crowded
conditions inevitably compete for light, namely, for an ability to photosynthesize. In this study, we addressed
correlation structures between traits essential for the response to changes in light quality and light intensity, in Lamium purpureum plants originating from two habitats (Open and Shade), in two natural populations
(Vršac mountain and Zuce) and grown in two densities (High and Low). Every single plant was planted in a
single pot and this arrangement allowed competition only for light and not for the other resources. We measured
eight traits after 8 weeks of growth: height, first and second leaf length, first and second leaf width and
number of leaves, number of internodes and number of shoots per plant. We aimed to test if there are statistically
significant phenotypic correlations between traits (morphological integration) and if they depend
on the population, habitat and density treatment. Correlation structures differed between habitats and treatments
in both populations. Plants in Vrsac/Shade habitat and Zuce/Open habitat, showed the lowest level
of between trait integration in the High light treatment. Between-population differences in correlation structures
were more numerous in the High light treatment for both habitats.
