摘要

本文报道了韩国人群中4个苔属植物类群的减数分裂染色体数目。3个是首次报道的韩国种群分类群:Carex appendiculata (Trautv);& C. A.梅。)Kuk。(n = 27 II);& Vaniot (n = 33 II)，和C. metallica h.l acei。(n=15 II)。其他物种的报道扩大了染色体数目变异的范围在一个分类单元，C. miyabei Franch。(n = 43 II, 44 II, 45 II)。Carex L. (Cyperaceae)在世界范围内有2000多种，是韩国种类最丰富的属。该属植物的物种多样性被认为与染色体变异有关，但有关韩国苔属植物的染色体信息尚不清楚。本文更新了韩国苔属植物180个分类群中24个的染色体数目清单。

Report on the chromosome numbers of four Carex taxa in Korea (Cyperaceae)

We report the meiotic chromosome numbers of four Carex taxa from Korean populations. Three are the first reports made on taxa from Korean populations: Carex appendiculata (Trautv. & C. A. Mey.) Kük. (n = 27 II ), C. fernaldiana H. Lév. & Vaniot (n = 33 II ), and C. metallica H.Lév. (n=15 II ). Reports on the other species expand the range of variation in the chromosome number within a taxon, C. miyabei Franch. (n = 43 II , 44 II , 45 II ). Carex L. (Cyperaceae) consists of more than 2,000 species worldwide and is the most species-rich genus in Korea. The species diversity in the genus has been hypothesized to be associated with the chromosome variation, but chromosome information pertaining to Korean Carex taxa is not well known. This report updates the chromosome number inventory on Korean Carex to 24 out of 180 taxa.
