Three East Asian Karyotypes of Abies

. K (2n) = 24; 14m (6SC) +10 sm, 1 ~ 7 number,[link widoczny dla zalogowanych], and 8 - l2 numbers were in the middle and near the centromere of chromosome, the short arm of chromosome 2,4 and 6 have a long arm Ten secondary constriction. The relative length of chromosome 3, Li Lin Elementary received three East Asian type of fir 291 plants consisted 2n = 24 = 2L + l2M2 +8 Ml +2 S. 1.53 average arm ratio of chromosome length ratio of 1.76,4 than the big arm of chromosome 2, is a 2A type.

AS · K% = 56.29. This species is reported to change the access type headed. Fauon (1990) system smithii in the fir, pine and fir Abies fir group were placed in Cangshan Sect.Pseudopicea (a Himalayan endemic in China), East Asia, and resistance to specific lipid fir fir group SectMomi group Sect.Balsamea. Car Nan (19951 think that if the geographical distribution point of view of Zhou widespread north temperate group of lipid fir may be more ancient, because at least the late Tertiary in the previous group had been formed when the stable manure, Abies most other areas may still be divided into specific groups . 3 Abies from this average arm ratio of chromosome length and the As · K% more than the value of such point of view, than Abies smithii Du fir and cedar and the karyotype symmetry than the original. From the available data (initial Li Lin ,[link widoczny dla zalogowanych], 19921 can also be found fir resin group Abalsamea .. 1asiocarpa,.
