Abstract: In this study the chromosomes of Picea meyeri Rehd were observed and the B- chromosome relative to peroxidase and cytochrome oxidase isozymes was analysised. The chromosome number in normal plant was 24. Most plants lacked B-chromosome. However, two B-chromosomes were found in very few plants. These few plants showed abnoemal fertility. Their diameter increment lower too. An additional Pb and was found in enzymograph of peroxidase in B-chromosome bearing plants, but lacked the Pa1, These Plants also produced an additional band of cytochrome oxidase Cb. These plants with B-chromosomes Showed specific isozyme pattern. We can regard the isozymes as a biochemical marker of the B-chromosome.
