Materials for karyotype analysis of Karelinia caspica are collected in Turpan Eremophytes Botanic Garden

Academia Sinica. The numbers of chromosomes in root-tip cells of the species are 2n=20

agreeing with those reported by Chouksanova (1968). A comparison of the karyotypical data is shown in Table 1. According to the chromosomal terminology defined by Levan et al.

the karyotype formula of Karelinia caspica is K(2n)=2x=20m. It belongs to "1A" type of Stebbins'karyotypic asymmetry.Photomicrographs

karyotype and idiogram of Karelinia caspica are shown in Figs. 1

2 and 3.
