Schematic representation of the experimental design. Juvenile and mature S. dulcamara plants originating from two habitats in two locations (four populations) were subjected to control, shallow flooding and deep flooding. Two plants per developmental stage per population were randomly allocated to each of the 15 non-transparent containers, resulting in a total of 30 plants per developmental stage per population. The three containers comprising each of the three treatments in a row were treated as a block.
