“…A maioria das espécies do gênero Paspalum tem como modo de reprodução a apomixia, o que implica populações geneticamente homogêneas (Quarín & Norrmann 1990). A apomixia dificulta a recombinação genética, assim como a proteção de cultivares pelas normas legais vigentes.…”

“…In Brazil, where 75% of Paspalum species occur, they are part of several plant communities, in a broad range of ecological conditions (Barreto, 1974). Sexual reproduction and apomixis are common in the genus, generally related to the diploid and polyploid levels (Quarín & Norrmann, 1990).…”

“…Poliploidy is frequent in the genus, with predominance of the tetraploid level (QUARÍN, 1992). Cytological studies show that many Paspalum 'species' consist of both sexual, self-incompatible diploid cytotypes, and apomictic, pseudogamous, and self-fertile polyploids (QUARÍN & NORRMANN, 1990;QUARÍN, 1992;VALLS, 2000). Thus, they can originate agamic complexes, in which the very concept of 'species' becomes doubtful.…”
