LOPEZ, Alberto et al. Cytogenetic characterization of Caesalpinia spinosa from Tarma and Palca (Junín). Rev. peru biol. [online]. 2013, vol.20, n.3, pp.245-248. ISSN 1727-9933.

Somatic chromosomes of Caesalpinia spinosa (Feuillée ex Molina) Kuntze, “Tara”, wild popu- “Tara”, wild populations of Huinco and Palca (Junín) regions were studied. The specie were diploid (2n=24). Chromosomes were small. The karyotypes showed the same chromosome number, they found differences in morphological parameters of the same, with the karyotype formula for the town of Huinco: 6m + 6 sm and the town of Palca: 5m + 7 sm.

Palabras clave : chromosome; submetacentric; metacentric; metaphase; karyotype.
