Microsporogenesis in Paspalum conspersum Schrad. (Virgata group) with different ploidy levels

L. Janke, Souza, F. H. D., Valls, J. F. M., and Pagliarini, M. S., Microsporogenesis in Paspalum conspersum Schrad. (Virgata group) with different ploidy levels, vol. 12, pp. 4948-4957, 2013.

Knowledge about the cytology and reproductive behavior of a species is indispensable for hybridization programs. This is especially true for species belonging to the genus Paspalum, among which apomixis and a wide range of ploidy levels are frequently found. Paspalum conspersum Schrad. is a robust and warm-season perennial bunchgrass native to South America. Previous studies have indicated that both tetraploid and hexaploid races exist in this species; however, only information related to tetraploids has been applied to another taxon.
