Aarnes group

The Aarnes group studies ammonium toxicity in duckweed. 


Gibbous duckweed (Lemna gibba L.)

About the group

Gibbous duckweed (Lemna gibba L.) is a fast-growing small aquatic monocotyledon covering nutrient rich eutrophic freshwater in ponds and canals. The leaf like structure is called a frond, and a thread-formed single adventitious root with a large root cap emerges from a node beneath each frond. Duckweed reproduce by vegetative clonal growth, but the plant also have small flowers and can produce seeds. We use duckweed as a model plant in the study of ammonium toxicity.
