Abstract

In previous investigations, natural layering of Japanese stone pine (Pinus pumila) was suggested by the occurrence of adventitious roots. However, there is no genetic evidence so far that this species actuallyproduces offspring by natural layering. We, therefore, investigated clonal structure and spatial genetic structure within a 38X18 m plot onMt Aino-dake, using allozyme, random amplified polymorphic DNA (RAPD), and inter-simple sequence repeat (ISSR) analyses. We found 24 genets, with stems found to be genetically identical in multiple tests, which extended laterally against the direction of the slope, indicating that there were clonal structures originating from elongation of ramified stems and subsequent natural layering. The results suggest, however,that less than one third of the 200 stems analyzed from this site were clonaly propagated. We also analyzed spatial genetic structure by spatial autocorrelation, Many of the spatial autocorrelation coefficients were significantly positive in short distance classes. We concluded that the species has genetic structures which largely originate from clonal propagation and avian seed dispersal.
