| Abstract: | Two alder species,Alnus glutinosa (L.) Gaertn. andAlnus incana (L) Moench, were inoculated with a Sp+
Frankia homogenate obtained fromA. incana root nodules. This inoculum formed effective nodules on the original host plant and ineffective nodules onA. glutinosa. Grafts between the two alder species were made to determine which part of the plant is involved in this phenomenon. The results obtained indicate that the compatibility between Alnus andFrankia is restricted to the root system. |
