SOUZA, Francisco Humberto Dübbern de; GUSMAO, Marcos Rafael; CAVALLARI, Marcelo Mattos  e  BARIONI JR, Waldomiro. Characterization of the potential of native grasses for use as lawns. Ornam. Hortic. [online]. 2020, vol.26, n.1, pp.109-120.  Epub 11-Maio-2020. ISSN 2447-536X.  http://dx.doi.org/10.1590/2447-536x.v26i1.2067.

Since long lawns have been cultivated worldwide to perform a large variety of functions. Brazilian lawns have been constituted by a reduced number of species and cultivars. This work was developed with the purpose of estimating the potential of use as lawns presented by the members of a collection of accesses of native species of Paspalum and Axonopus (Poaceae). The following characteristics were evaluated: maximum vertical growth height, speed of soil cover, speed of regrowth, dry mass production, ornamental quality, weed encroachment and demand for mowing. Several accessions presented desirable characteristics and can therefore be included in programs aiming the development of cultivars for lawns intended for use in a variety of situations. The results here reported and discussed represent an experimental verification of the potential of the Brazilian flora to offer plants for use as lawns, reinforce the importance of native genetic resources and contribute to the continuity of research aimed at the development of this type of cultivars in Brazil.

Palavras-chave : Paspalum; Axonopus; Poaceae; genetic resources; landscaping; turfgrass.
