摘要

本文报道了在阿尔及利亚东北部Skikda地区两个不同沿海地区采集到的海菊(Anthemis maritima)复合体的两个亚种的染色体数目和核形态。在整个地中海地区都很常见的海苔，以及海苔亚种。bolosii是一种严格的阿尔及利亚地方病，在消失100年后最近被重新发现。Feulgen染色法显示海菊属亚种。洋菊是四倍体，有2n=4x=36条染色体(2n=11m+3sm+4st)。Bolosii是二倍体，有2n=2x=18条染色体(2n=4m+3sm+2st)。根据Stebbins的分类，这两个分类群都有对称的核型，分别是2A和1A。这些发现对于海洋洋菊亚种来说都是新颖的。阿尔及利亚的海菊种群。maritima。

Karyomorphology of two subspecies of Anthemis maritima (Asteraceae) from Algeria

The chromosome number and karyomorphology of two subspecies of the Anthemis maritima complex collected from two different coastal localities in the Skikda region (northeastern Algeria) are reported in this study: Anthemis maritima subsp. maritima, which is common throughout the Mediterranean, and A. maritima subsp. bolosii, a strict Algerian endemic recently rediscovered after 100 years of disappearance. The Feulgen staining method indicated that Anthemis maritima subsp. maritima is a tetraploid with 2n=4x=36 chromosomes (2n=11m+3sm+4st), and Anthemis maritima subsp. bolosii is a diploid with 2n=2x=18 chromosomes (2n=4m+3sm+2st). Both taxa have symmetrical karyotypes, 2A and 1A, respectively, according to Stebbins classification. These findings are novel for both the subspecies Anthemis maritima subsp. bolosii and the Algerian population of Anthemis maritima subsp. maritima.

期刊介绍： Caryologia is devoted to the publication of original papers, and occasionally of reviews, about plant, animal and human karyological, cytological, cytogenetic, embryological and ultrastructural studies. Articles about the structure, the organization and the biological events relating to DNA and chromatin organization in eukaryotic cells are considered. Caryologia has a strong tradition in plant and animal cytosystematics and in cytotoxicology. Bioinformatics articles may be considered, but only if they have an emphasis on the relationship between the nucleus and cytoplasm and/or the structural organization of the eukaryotic cell.
