Karyological and allozyme variation in pinus densiflora for. multicaulis uyeki

Variations in karyotype analysis and band patterns of isozymes extracted from needles were compared between Pinus densiflora and P. densiflora for. multicaulis. The morphological differences were observed in eight chromosomes between the two species, when they were arranged in the descending order of length of the chromosomes. The variation in C band by band stain method differed in many number chromosomes between the two species. The behavior of chromosomes during the meiosis stage was normal between the two species. The band of Rf value 33 in needle peroxidase was specifically characterized by P. densiflora, whereas that of Rf value 69 by recessive gene of P. densiflora for. multicaulis. The bands of Rf valus 60 in needle estrase and of Rf value 56 in male strobile might be expressed only both by P. densiflora and P. densiflora for. multicaulis.
