Abstract: | The ability of Hawaiian volcanic soils to nodulate actinorhizal Myrica cerifera, Casuarina equisetifolia, and Alnus glutinosa was determined using a host-plant bioassay. Myrica-nodulating Frankia occurred in five volcanic deposits with depositional ages ranging from 20 to 162 years before present. The oldest deposit had a mean estimated nodulation capacity from 450 to 1200 times greater than those of the younger deposits. Only the oldest deposit had high moisture content, high organic matter content, and increased vegetative cover, including an abundance of actinorhizal M. faya. Casuarina- and Alnus-nodulating Frankia were not detected in any of these volcanic deposits. |
