Summary

Detailed microsporogenesis in 4 species of the genus Pennisetum namely P. typhoides (n = 7), P. longistylum (n = 18), P. polystachyon (n = 27) and P. pedicellatum (n = 27) was studied. Nature of chromosome pairing was critically studied and pairing was regular in diploid and allotetraploid species. Some multivalents formation occurred in segmental allopolyploids. They displayed numerous meiotic irregularities. Aberrant meiosis in the material is evaluated. The role of apomixis, hybridization and polyploidy in the evolution of the genus is discussed.

Zusammenfassung

Es wird über eingehende Untersuchungen der Mikrosporogenese in 4 Species der Gattung Pennisetum, nämlich P. typhoides (n = 7), P. longistylum (n = 18), P. polystachyon (n = 27) und P. pedicellatum (n = 27) berichtet. Die Art der Chromosomenpaarung wurde kritisch geprüft, sie war bei den diploiden und allotetraploiden Species regulär. Multivalentbildung trat in einigen Fällen bei Segment-Allopolyploiden auf, sie zeigten zahlreiche meiotische Unregelmäßigkeiten. In dem Material aufgetretene aberrante Meiosen wurden ausgewertet. Die Rolle von Apomixis, Hybridisation und Polyploidie bei der Evolution der Gattung wird besprochen.
