The Brazil today has a large part of forest land that is degraded, due to inadequate planning and management, resulting in productivity loss and a disturbing environmental impact. It becomes evident the need to create more effective management strategies and government plans to address this problem, such as the "National Plan for Recovery of Native Vegetation - PLANAVEG." However, the major failure cause of degraded area recovery programs is due to competition with weeds, which in addition to disputing for water, space and radiation with native species can still cause damage through allelopathy. In view of such circumstances chemical control through the herbicides application can increase the success chances of the restoration programs, besides, the correct use of the native species resistant to the applied herbicides can increase the operational income and facilitate the program progress. In the world literature there are few studies on the characteristics that influence the resistance or susceptibility of native species to a herbicide. In this way, we will study the selectivity of different herbicides in native species, selecting the most sensitive and resistant species and analyzing different aspects of their morphology, anatomy and physiology, in order to understand if there is a relation with the resistance characteristic.
