Other claims from this paper (7)
- Association Frankia isolate and Alnus clone each significantly affected postinoculation height and diameter growth.
- Association Frankia isolate-by-Alnus clone interaction was not statistically significant.
- Observation All host-isolate combinations formed nitrogen-fixing nodules.
- Intervention effect Alnus with the Comptonia Frankia isolate more than doubled stem diameter growth relative to the A. crispa isolate.
- Observation The A. glutinosa clone grew at least four times faster in height than the other Alnus clones after Frankia inoculation.
- Observation The A. glutinosa clone grew at least twice as fast in diameter as other Alnus clones after Frankia inoculation.
- Recommendation The authors propose selecting Frankia isolates and host genotypes to improve growth rates.
