contents Citogenética de Guazuma ulmifolia var. Ulmifolia (Sterculiaceae) Fernando Tapia-Pastrana Biología Mexico Guazuma karyotype Sterculiaceae nucleolar organizers A surface spreading and air-drying method to obtain for the first time the somatic karyotype of apopulation of Guazuma ulmifolia var. ulmifolia was used. Chromosome diploid number of 2n = 16from meristematic root cells was confirmed. Mitotic karyotype was 14m + 2st with a slight asymmetry(T.F.% = 42.19). Total haploid chromosome length was 11.65 µm with a chromosomal interval of 1.11- 2.05 µm. Nucleolar organizers were associated to secondary constrictions on the pair 3 (m), and apolymorphism was observed on the pair 8 (st). These two features could be employed as cytogeneticmarkers in future studies for other species and varieties of the genus. 2007 artículo científico 0011-6793 https://www.redalyc.org/articulo.oa?id=66945103 en http://www.redalyc.org/revista.oa?id=669 Darwiniana application/pdf Instituto de Botánica Darwinion Darwiniana (Argentina) Num.1 Vol.45
