ABSTRACT
The slow and desuniforme germination seeds of palm trees brings problems in the propagation of the species belonging to this family, more difficult, primarily, the production of seedlings on a commercial scale. This work objective was to determine the effect of the size seed, substrates and the environment in emergency of Copernicia hospita Martius seedlings. Seeds were referred to treatments: substrates [(red sand + carnauba straw + humus (2,5:2,5:1 by volume) and soil + dark sand + organic compound Polefértil® (2:2:1 by volume)]; environments (sun and house of vegetation), and size seed (small, medium, large and mix). The treatments were compared in terms of emergency percentage, estimated to 60 days after sowing, speed emergency index and mean emergency time. The factors examined not affect the emergency percentage seedlings. Seeds of C. hospita mixing and small size, sown in both substrates, under house of vegetation, provide emergency fastest of the seedlings.
