Saponins and Sapogenins from Brachiaria decumbens Stapf
Quatro saponinas esteroidais e três sapogeninas foram identificadas das partes aéreas de Brachiaria decumbens. As estruturas desses compostos foram estabelecidas através de métodos químicos e espectroscópicos (RMN de H e C, HMBC, HMQC) como 3 -metóxi-lanost-9(11)-eno (1), diosgenina (2a), iamogenina (2b), 3-O-D-glicopiranosil-24(S)-etil-22E-deidrocolesterol (3a), 3O-D-glicopiranosil-24(R)-etil-...
متن کاملMicrosporogenesis in Brachiaria dictyoneura (Fig. & De Not.) Stapf (Poaceae: Paniceae).
Microsporogenesis was analyzed in five accessions of Brachiaria dictyoneura presenting x = 6 as the basic chromosome number. All accessions were tetraploid (2n = 4x = 24) with chromosome pairing in bi-, tri-, and quadrivalents. The recorded meiotic abnormalities were those typical of polyploids, including precocious chromosome migration to the poles, laggard chromosomes, and micronucleus format...

15 صفحه اولMicrosporogenesis in tetraploid accessions of Brachiaria nigropedata (Ficalho & Hiern) Stapf (Gramineae).
The genus Brachiaria (Trin.) Griseb. has achieved considerable importance to cattle production systems, as a result of the good production and adaptation of a few cultivars to poor and acid soils of the Brazilian savannas. Many of its species and accessions are polyploid and apomictic, which limits direct hybridization. To assist the breeding program, cytogenetic characterization has been under...
