Cytogenetic studies in some representatives of the subfamily Pooideae (Poaceae) in South Africa. 3. The tribe Poeae

Abstract: This is a report on chromosome numbers for the tribe Poeae, which is represented in South Africa mainly by naturalized exotics. Chromosome numbers of 67 specimens, representing 26 species and 11 genera, are presented. These numbers include the first reports on Poa binata Nees (n = 3x = 21 and n = 4x = 28), Puccinellia acroxantha C.A.Sm. CE.Hubb. (n = 3x = 21) and P. angusta (Nees) C.A.Sm. C.E.Hubb. (n = x = 7). New ploidy levels are reported for Catapodium rigidum (L.) CE.Hubb.(n = 2x = 14), Festuca caprina … Show more

“…To determine polyploid types present in the studied specimens, the Kimber and Alonso model (Kimber & Alonso, 1981) was used to investigate genome relationships in tetraploid specimens. This model was chosen because it provided us with very good results in a number of different plant groups [for example Lantana camara L. (Spies & Stirton, 1982;Spies, 1984), Rubus L. and various grass subfamilies (for example Spies & al., 1990Spies & al., , 1996Spies & al., , 1997Klopper & al, 1998;]. Even though the chromosomes studied are very small, meiotic configurations could be studied under 100× oil magnification.…”

“…El transcorte foliar de F. asplundii fue descrito por Stančík & Peterson (2007) Spies et al 1997Spies et al , 1999, nativa de Europa, e introducida en Sudamérica (Venezuela a Chile). Sin embargo, esta relación de F. subulifolia con las especies del clado Vulpia (2x) no se observa en todos los análisis; se obtiene con la matriz combinada (IB) y con la matriz de ITS (IB y MP).…”
