Chromosome Atlas of Eight Asteraceae Species from the Qinghai-Tibet Plateau

doi:10.7677/ ynzwyj201313034

Abstract

Abstract:

The chromosomes of eight species of the family Asteraceae from the Qinghai-Tibet Plateau were investigated. Chromosome numbers and karyotypes of six species were presented in this paper for the first time. Based on
Stebbin爷s classification, the karyotype formulas and asymmetry were enumerated as follows: Cirsium souliei 2n =34m, 1A; Cousinia thomsonii 2n =26=22m+4sm, 2A; Crepis minuta 2n =14=10m+4sm, 2A; Ligularia liatroides
2n =60=32m+28sm, 2A; Saussurea thomsonii 2n = 36 = 22m+14sm, 2A; Taraxacum tibetanum 2n = 16 = 10m+6sm, 1A. The chromosome numbers and karyotypes of other two species reconfirmed previous reports.

Key words: Chromosome, Karyotype, Asteraceae, Qinghai-Tibet Plateau
