CHROMOSOMAL NUMBER OF A POPULATION OF ALSTROEMERIA PELEGRINA L. (ALSTROEMERIACEAE), ENDEMIC SPECIES OF CHILE

Abstract

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 Valparaíso), 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.
