ABSTRACT
Seeds healthy and rapid development of seedlings of native species may be critical to the success of your establishment. This study evaluated the effect of Trichoderma spp. on seed and seedling development of Parapiptadenia rigida (angico), Cedrela fissilis (cedro) and Pelthophorum dubium (canafistula). The fungi was applied at different times of the production of seedlings. The fungi action was different between species and between the variables. Cedro was less responsive to application of Trichoderma spp. at any time of the seedlings production and the association of Trichoderma spp. With angico as the seed treatment favored the incidence of some pathogens, however the application later favored only the leaves development. In canafístula, the seed treatment provided control of pathogens associated and stimulated the emergence and production of leaves in seedlings, have potential to be used for seed treatment of this species.
