| Outline of Final Research Achievements |
Genetic structure and the effect of local tree density on self-fertilization ratio were studied for spruce species in two sites of different local tree density in a severely degraded spruce forest at Mt. Ohdaigahara. Eight microsatellite marker were used to the analysis. Self-fertilization ratio and biparental inbreeding were calculated, then pollen dispersal distance were estimated with male parent analysis. At both sites no relation was found between local density and self-cross ratio, while biparental inbreeding was generated. Pollen dispersal distance was not significantly different between two sites, although mother trees were supplied more pollen from closer mature trees.
