Conteúdo: | The possible adaptation of nine species of the genus Stylosanthes SW., represented by 39 accessions, to a latitude of about 30[graus]N and evaluation of their feed quality was investigated. The Beef Research Unit (BRU) near Gainesville, Florida was chosen for the experimental site. Stylosanthes hamata (L) Taub. was the species which showed the best adaptation followed by Stylosanthes scabra Vog.. Stylosanthes guyanensis (Aubl.) Sw. seemed to be the least adapted species to this latitude and climatic environment as measured by flowering characteristics. This species had a high percentage of accessions that either did not flower or did not produce any seed. Photoperiod was the main factor affecting flowering. Different daylength requirements were observed between and within species. No difference (P<0.05) was evident in percent IVOMD between means of the predominantly erect plant types (Stylosanthes scabra Vog.) and the generally prostate ones [Stylosanthes guyanensis (Aubl.)Sw.]. The IVOMD ranged from 66.6% to 49.6% and percentage of leaves from 64,9% to 46.4%. The correlation between percent IVOMD and percentage of leaves was positive (r=0.19). The variation of IVOMD and percentage of leaves was greater within than between accessions.
