摘要：

Nitrogenase activity as assayed by acetylene reduction was observed in detached Rubus ellipticus J. E. Smith root nodules collected in the field and tested under ambient conditions. The nitrogenase activity was 8.4 μmoles C2H4.gfr. wt nodule-1.h-1 or 24.0 μmoles C2H4.g dry wt nodule-1.h-1 being at a rate comparable with that measured in some other non-legumes assayed in Java at the same time under similar conditions. Nodule morphology bore little resemblance to the root nodules of other non-leguminous plants and nodule structure was different from the other rosaceous examples. The endophyte inhabiting the root nodules was actinomycetal. © 1979 Martinus Nijhoff Publishers.
