内容記述 | Allele frequencies of isozyme genes were compared between a mother stand and its progeny stand to reveal the actual condition of genetic diversity in an artificial forest of Chamaecyparis obtusa. Genetic diversity of the mother stand was maintained in the progeny stand for the most part. However some genetic offsets were observed in specific loci, which might be caused by biased seed collection from a limited number of mother trees. Therefore seed collection from large a number of mother trees is necessary to conserve the genetic diversity of the mother stand. Comparison between the progeny stand and the cutting stand of which stocks were taken from the progeny stand was undertaken. The expected heterozygosity of the cutting stand was lower than that of the progeny stand owing to the existence of plural individuals belonging to same clones. However, the expeceted heterozygosity of the cutting stand was almost the same as the progeny stand when individuals belonging to the same clone were considered as individuals. Accordingly, it is possible to conserve the genetic diversity even in a cutting stand by taking stocks from a reasonable number of mother trees. | |||||
