Variety description
10 August 2026
The variety is a floating aquatic plant for which standard agricultural description parameters, such as height or lodging resistance, are not applicable. The plant is characterized by rapid vegetative clonal propagation.
When cultivating the variety, the main focus is on optimizing lighting conditions, nutrition, and carbon dioxide levels to obtain biomass of stable chemical composition. The cultivation process involves cyclic partial harvesting and the prevention of biomass contamination by algae.
