title: [Karyotype analysis of Astragalus complanatus chromosome].
abstract: Micrograph were used to analyse the number, karyotype and volume of chromosome of Astragalus complanatus. The normal diploid 2n = 16, karyotype formula based on Levean publication (1964) was K(2n) = 16 = 10 m + 6 sm. According to the method of S.R. Guo, the chromosome relative length was 2n = 16 = 6M2 + 10M1, which belonged to "2A" type according to the Stebbins' karyotype classification. The total length of chromosome groups was 33.05 microns, total length of long arms was 19.76 microns, from Arano's method the AS.K% was 59.79%. The total volume of chromosome was 50.6 micron 3.
