Abstract

Cytogenetic analysis of Anemarrhena ashodeloides BUNGE, which is one of medicinal plants belonging to Haemodoraceae was carried out using Feulgen staining. The somatic metaphase chromosome number was identified to 2n=22 (x=11) and the size of chromosomes ranges from $1.27-3.80\;{\mu}m$. Three pairs of chromosomes were relatively long in total length and the others were short. The karyotype was bimodal in chromosome length and arm ratios. The chromosome complement comprise eight pairs of metacentric (chromosome 2, 3, 6, 7, 8, 9, 10, and 11), two pairs of submetacentric (chromosome 4 and 5), and one pair of subtelocentric (chromosome 1).

약용으로 재배되고 있는 지모의 세포유전학적인 연구인 핵형 분석 결과는 다음과 같다. 지모의 체세포 염색체 수는 2n=22였으며. 외형으로 비교해 보았을 때, 3쌍의 상대적으로 길이가 긴 염색체와 길이가 짧은 8쌍의 염색체로 구별이 되었다. 염색체의 평균 길이는 염색체의 길이는 $1.27-3.80\;{\mu}m$로 관찰되었다. Armatio 비교를 통한 핵형 분석에서는 8쌍의 중부 염색체 (염색체 2, 3, 6, 7, 8, 9, 10 및 11), 2쌍의 차중부 염색체 (염색체 4와 5) 그리고 1쌍의 차단부 염색체 (염색체 1)로 구분되었다.
