摘要

以前有对智利特有物种Alstroemeria pelegrina的细胞学研究，但没有一项明确表明所研究材料的位置。对从洛斯莫尔斯（瓦尔帕莱索地区）采集的一个pelegrina Alstroemeria种群进行了细胞分类学分析。结果表明，该群体具有2n=16条染色体，核型单倍体为3m+1sm+2st+2t。通过将该种群的生物特征数据和核型的不对称性指数与先前公布的数据进行比较，得出结论，它肯定是同一物种。

NÚMERO CROMOSÓMICO DE UNA POBLACIÓN DE ALSTROEMERIA PELEGRINA L. (ALSTROEMERIACEAE), ESPECIE ENDÉMICA DE CHILE

There are previous cytological studies in Alstroemeria pelegrina, an endemic species of Chile, but none of them clearly indicates the location of the material studied. A population of Alstroemeria pelegrina, collected from Los Molles (Region of Valparaiso), was analyzed cytotaxonomically. It was found that this population presents a 2n = 16 chromosomes and a caryotypic haploid formula 3m + 1sm + 2st + 2t. By comparing the biometric data and asymmetry indices of the karyotype of this population with previously published data, it is concluded that it is definitely the same species.
