Modular Structure of Inflorescences of Two Species from the Genus Hydrangea L.

摘要

The structure of the complex inflorescences of Hydrangea petiolaris Siebold et Zucc. and Hydrangea paniculata Sieb. was studied using physiognomic, structural, and fractal approaches. It is established that physiologically different inflorescences have a general structure, pleiothyrse, and the same number of flowers. The structure of inflorescences is generally orderly and has a modular organization. Changes in the structure of inflorescences occur in parallel in all modules owing to a reduction or an underdevelopment of flowers in each of the modules.
