Summary

Coprosma robusta Raoul plants grown in plus- and minus-nitrogen sand culture showed no significant response to removal of stipules. Acetylene reduction assays for nitrogenase on leaves and stipules gave negative results for six Coprosma species. Two unwashed root samples showed slight acetylene reduction and this was ascribed to casual aerobic rhizosphere organisms.
