Abstract

Abstract: Chromosome numbers and karyotype of Arenaria roborowskii(Caryophyllaceae ) from Hengduan mountains were studied in this paper . The results showed that the karyotype formulas is 2 n =2 x =22 = 22mwith type 1A asymmetry . The interphase nuclei and prophase chromosomes of the specie were found to be of the complex chromosome type and interstitial type .

Key words: Karyotype
