Abstract

Regarding architectural adaptations in aquatic plants caused by the velocity of water flow only scarce, older information is available. When studying different Myriophyllum spicatum L. specimen architecture in the same water body differences in individual main axes and branching pattern were detected at the upstream and at the downstream end of individual plant beds. Samples from the two locations showed significant differences in architectural composition. At the downstream parts of the water body individual plants were longer and the number of branches was higher, which is contributed to flow velocity.
