Fortunato Lidia Poggio Biología polyploidy cytogenetics series Farinosae subseries Mimosa Chromosome asymmetry The first karyotype studies in Mimosa farinosa and M. velloziana are presented. The chromosome number of M. farinosa, 2n = 2x = 26 (Mimosa section Batocaulon series Farinosae) is mentioned for the first time, while the chromosome number of M. velloziana var. velloziana, 2n = 4x = 52 (Mimosa section Mimosa series Mimosa subseries Mimosa) is confirmed. The formula and parameters of karyotype (chromosome length and A1 and A2 asymmetry indexes) were analyzed. The karyotype formula of M. farinosa (16m+10sm) and M. velloziana var. velloziana (48m+4sm) were calculated. Mimosa farinosa has a more asymmetric karyotype and larger chromosome size than M. velloziana var. velloziana. A1 index, total chromosome length, and chromosome length per haploid genome showed significant differences between the two taxa. These results agree with differences previously found among other members of series Farinosae and subseries Mimosa, suggesting that certain karyotype parameters could have cytotaxonomic interest in some groups of species of this genus. 2015 artículo científico 0524-0476 https://www.redalyc.org/articulo.oa?id=685773783009 es http://www.redalyc.org/revista.oa?id=6857 Bonplandia application/pdf Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) Bonplandia (Argentina) Num.1 Vol.24 |
