title: [Study on karyotype and giemsa C-banding of Aquilaria sinensis].
abstract: OBJECTIVE
  To study Aquilaria sinensis (Lour.) Spreng chromosome karyotype and C-banding.
  
  
  METHODS
  Sections for karvotvpe and BSG method for C-banding.
  
  
  RESULTS
  The somatic chromosome number was 2n=16, karyotype formula was K(2n) = 2x = 16 = 6m + 6sm + 4st, based on Levan's publication in 1964. According to the method of Kuo, the chromosome based on the relative length was 2n = 16 = 4L + 4M2 + 6M1 + 2S, which belonged to "2B". 8 pairs chromosomes had 34 C-bands and the C-banding patter was 2n = 2x = 16 = 4C + 2I + 2T + 2CI+ + 2CI+ T + 2CI+ T+ + 2I+ T+.
  
  
  CONCLUSIONS
  The data of karyotype and C-banding indicated A. sinensis chromosome had a relatively high asymmetry and was in the advanced stage of evolution, which offered the evidence for further genetic analysis.
