Última Morphology of seeds and seedlings of four species of Vigna Savi (Leguminosae, Phaseolinae) 39 Ojeda,Fabiana Soledad; Hoc,Patricia Susana; Amela García,María Teresa. Four neotropical species of Vigna Savi (Leguminosae, Phaseolinae) have potential value as forage crops or ornamentals and could be cultivated in tropical or subtropical areas, even on floodplains. In order to obtain useful data for their culture and taxonomy, the seed morphology, germination pattern (hypogeal or epigeal) and seedling development were studied. The studied species belong to different sections of the genus: V. adenantha (G.F.W. Meyer) Maréchal, Mascherpa & Stainier (Sect. Leptospron); V. candida (Vell.) Maréchal, Mascherpa & Stainier (Sect. Sigmoidotropis); V. caracalla (L.) Verdc. (Sect. Caracallae) and V. luteola (Jacq.) Benth. (Sect. Vigna). The seeds were collected during fieldwork conducted in northwestern and...

Ano: 2013 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0102-33062013000300004 Breeding system and related floral features under natural and experimental conditions of Passiflora suberosa (Passifloraceae) 51 Amela García,María Teresa. The breeding system, the floral characteristics and the visitors of the polymorphic Passiflora suberosa were studied in different natural populations of Corrientes and Misiones provinces, and at a partially-opened greenhouse in Buenos Aires. The different reproductive indexes calculated evidenced that, although it is highly self-compatible, autogamy is partial. The reproductive efficiency was similar in the field and in the greenhouse. The major relative reproductive success obtained by induced self-pollination suggests that the reproductive output may be improved with the help of pollinations, either natural or artificial. Although the single flower and the blooming are inconspicuous, the floral characters may be involved in wasps attraction. The scarcity...

Ano: 2008 URL: http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S1851-23722008000100006 Estudios citogenéticos en especies de Passiflora subgénero Passiflora (Passifloraceae) 51 Chiapero,Ana Laura; Las Peñas,María Laura; Amela García,María Teresa; Bernardello,Gabriel. Passiflora comprende alrededor de 525 especies con x = 9 ó 6. Se realizó un estudio citogenético de cuatro especies del subgénero Passiflora que crecen en la Argentina. Se utilizaron las técnicas de Giemsa, bandeo cromosómico fluorescente CMA/DAPI y FISH (sonda 18-5,8-26S y 5S) en cromosomas mitóticos. P. caerulea, P. tucumanensis y P. cincinnata resultaron diploides (2n = 18) mientras que P. mooreana, tetraploide (2n=36). Los cariotipos fueron altamente simétricos con la fórmula 8 m+ 1 sm, duplicada en P. mooreana. Con CMA/DAPI, todos los diploides presentaron dos o tres pares de bandas terminales CMA + /DAPI - , mientras que la especie tetraploide presentó cinco pares, asociadas a NOR. Con FISH, los loci 18-5,8-26S coincidieron en número y posición con... Tipo: Info:eu-repo/semantics/article Palavras-chave: Passiflora Cariotipos Heterocromatina ADNr 5S and 18-5; 8-26S.
