Summary A method is described for thein situ assay of acetylene reduction activity in the rhizosphere of rice involving the use of inexpensive, lightweight equipment. The assay is quick to set up and thus many replicates can be run simultaneously. Control of any acetylene-reducing blue-green algae in the assay chamber is achieved with a photosynthetically active herbicide which has no measurable effect on rhizosphere activity. Results using this method are compared with those from an excised root assay of the same plants. Only a very weak correlation between the two methods was found.
