Abstract

A detailed karyotype analysis was carried out in five Korean native Iridaceae species; Iris pseudoacorus, I. pallasii. var. chinensis, I. tectrum, I. dichotoma and Belamcanda chinensis. Chromosome compositions of the five species showed that they have different karyotypic formulae; I. pseudoacorus 2n=34=10m+16smn+8st including two pairs of satellite chromosomes, I. pallasii var. chinensis 2n=40=26m+12sm+2st including two pairs of satellite chromosomes, I. tectrum 2n=30=14m+16sm including five pairs of satellite chromosomes, I. dichotoma 2n=32=22m+10sm including two pairs of satellite chromosomes, and B. chinensis 2n=32=20m+10sm+2st including one pair of satellite chromosomes. These results will supplement the previous cytogenetic reports in Iridaceae species and enhance our understanding on the genetic structure, which will be useful in clarifying the unique characteristics of each species for practical breeding programs for horticultural and pharmaceutical purposes.

한국 자생 붓꽃과 식물 5종 (노랑무늬붓꽃, 타래붓꽃, 연미붓꽃, 대청부채, 범부채)에 대한 핵형분석 보충 연구를 수행하였다. 5종의 염색체는 모두 이배체였으나 염색체 수와 핵형적 조성에 있어서는 종에 따라 차이를 나타냈다. 노랑무늬붓꽃의 핵형식은 2n=34=10m+16sm+8st로 2쌍의 부수체 염색체를, 타래붓꽃은 2n=40=26m+12sm十2st로 2쌍의 부수체 염색체를, 연미붓꽃은 2n=30=14m+16sm으로 5쌍의 부수체 염색체를, 대청부채는 2n=32=22m+10sm으로 2쌍의 부수체 염색체를, 범부채는 2n=32=20m+10sm+2st로 1쌍의 부수체 염색체를 포함하고 있었다. 본 연구 결과 이들 5종 식물에 대해 이전 핵형보고와는 다른 염색체 수와 부수체 염색체의 존재를 확인할 수 있었다. 이 결과는 각종의 세포유전학적 규명에 유용할 것으로 여겨지며, 또한 원예용 및 약용가치로 개발의 가치가 기대되는 붓꽃과 식물의 실용화 작업에 유용한 기초 자료가 되리라고 본다.
