영문 초록

Taxonomical relationship of the five Pinus species in the subgenus haploxylon was investigated by karyological and isoperoxidase band pattern analysis, which would provide fundamental informations for further research on the economically important tree species in Korea: The chromosome number of each species was all the same with 2n = 24, but the relative length of the whole chromosomes was different from species to species. When the length of the chromosomes of each species was arrayed in the long and short arms, the order of the lengths of the chromosomes with the long and short arms was not coincidental with that of the lengths of the whole chromosomes among species. Interspecific differences were noticed not only in the position of the centromere on each chromosome but also in the numbers and locations of secondary constrictions. Isoperoxidase band patterns of each needle changed in accordance with the needle ages and seasons, but several bands of each species appeared consistently enough to show the difference and similarity among species. It is concluded that karyotype and isoperoxidase analyses can effectively be used in identifying the individual species and their interrelationship of these five soft pine species.
