Abstract

Abstract:

The chromosome numbers and karyotypes of five species of the genus Leontopodium (Asteraceae) from Southeastern QinghaiTibet Plateau, Southwest China were investigated. Three species were studied karyomorphologically and reported for the first time: L.franchetii 2n=2x=26=6M+18m+2sm, 2A; L.calocephalum 2n=4x=48=3M+43m+2sm, 1B; L.stracheyi 2n=4x=48=13M+35m, 1A. Two species L.souliei and L.sinense presented different chromosome numbers and karyotypes from the previous reports, that is, L.souliei 2n=2x=24=13M+8m+3sm, 1B; L.sinense, the population collected at altitude 2406m a.s.l. Muli County, Sichuan Province: 2n=2x=26=4M+22m, 1B, the population collected at altitude 3074m a.s.l. Muli County, Sichuan Province: 2n=4x=52=16M+36m, 1B. The comparison of existent chromosomal data indicates that Leontopodium is a genus with symmetry karyotype, but diversified obviously among different species. Polyploidization might have played an important role in the speciation and evolution of Leontopodium on the QinghaiTibet Plateau and its southeastern peripheral regions.

Key words: Leontopodium, Qinghai-Tibet Plateau, Chromosome number, Karyotype, Polyploidy
