摘要
大别山五针松的染色体基数X=12,除了第12对染色体最短且具亚中部着丝点以外,其余11对染色体长度相近且具中部着丝点。大别山五针松在核型上与红松、新疆五针松和华山松相似。
Descriptions of Karyotype of analysis of Pinus dabeshanensis(based primarily on centromere location and arm lengths)are presented. Results for this species are similar to those obtained in previous studies on Pinus spp. lt has a haploid complement of 12 chromosome, and except the 12th chromosome which is the smallest and possesses submedian centromeres, the other 11 chromosomes possess median centromeres and are rather similar in total length. The karyotype is similar to those of P. korainensis. P. sibirica and P. armandii.
