| 摘 要： | 报道了中国起源的松属三个种的胰酶—吉姆萨C—带核型.马尾松、油松、黄山松的中间带分别为34,24,24条,着丝粒带分别为18,20,20条,而对于一条染色体臂来说,最多出现一条或二条中间带.所有带纹的形态相似.而大小各异.在同一有丝分裂相中,中间带到着丝粒的距离相等(在仅出现一条带的臂上).三个种C—带在分布上的主要区别是:马尾松有一条染色体不显任何带,而油松和黄山松所有染色体均显带.

| Abstract: | The present paper reports the trypsin-Giemsa C - banded karyotypes of three species of Pinus massoniana,P. tabulaeformis and P. taiwanensis from China. They possess 34,24,24intercalary C-bands and 18,20,20 centrometric C-bands respectively. Each chro-mosome arm has two intercalary C-bands at most. All the bands have the same shape,but different size. In the same mitotic cell,The distance from the intercalary band to the cen-tromere is equal on the chromosome arm which has one band only. The major differences in distribution of C-heterochromatin among the three species are that P. massoniana has one pair of chromosomes which do not possess any C-band while both P. tabalaeformis and P. taiwanensis have one C-band at least on each chromosome. Evolution of karyotypes of the three species is discussed bassed on the analysis of the C-banding patterns. |
