RESUMOObjetivou-se com o trabalho, verificar existência ou não de dormência tegumentar e estabelecer uma metodologia para sua superação (caso ocorra) em sementes de canafístula, pau-jacaré, fedegoso, vinhático e pau-santo. Foram testados os seguintes tratamentos para superação da dormência: sem tratamento prévio (Controle); escarificação com ácido sulfúrico P.A. por 5 minutos (H 2 SO 4 ); imersão em água a 100º C por 5 minutos e embebição em água em temperatura ambiente por 24 horas. Para o pau santo, não se utilizou o tratamento de escarificação em ácido sulfúrico. A escarificação química se mostrou eficiente para promover a quebra da dormência de canafístula e vinhático. Nenhum dos tratamentos pré-germinativos avaliados se mostrou eficaz para promover a quebra de dormência do Fedegoso. Não foi observada dormência tegumentar para sementes de pau-santo e pau-jacaré, no entanto, a embebição em água por 24 horas favorece a germinação de ambas as espécies. PALAVRAS-CHAVE: Dormência tegumentar, Escarificação e Embebição. GERMINATION AND OVERCOMING DORMANCY IN SPECIES SEEDS FOREST ABSTRACTThe objective of the study was to verify whether cutaneous numbness is present and establish a methodology to overcome them (in the event) in seed tariff alligatorin seeds of Canafístula, Pau jacaré, Fedegoso, Vinhático and Pau Santo. The following treatments were used to overcome dormancy: untreated group (control); PA scarification with sulfuric acid for 5 minutes (H2SO4); immersion in water at 100°C (212° F) for 5 minutes and soaking in water at room temperature for 24 hours. It were not used the treatment of scarification in sulfuric acid for Pau Santo. The chemical scarification proved efficient to break the dormancy of canafístula and vinhatico. None of the pre-germination treatments evaluated was were (plural, nao singular) effective to promote of the breaking of dormancy breaking in Fedegoso seeds. There

Mining results in major landscape changes. Restoring areas after exploitation of natural resources can be accomplished through adopting techniques used to optimize the restoration process. Among such techniques, planting seedlings of species adapted to adverse edaphoclimatic conditions and which have interspecific associations with microorganisms stand out. One of these indigenous species which occur in the Southern Espinhaço Mountain Range with potential for use in restoring degraded areas is Kielmeyera rubriflora (Spreng) Mart. Thus, the objective of this study was to evaluate the influence of inoculating arbuscular mycorrhizal fungi on the survival and growth of Kielmeyera rubriflora Cambess. on two substrates from iron mining. The experiment was carried out in a nursery of the UFVJM Plant Species Propagation Center (CIPEF) in a randomized block design and treatments arranged in a 2 x 2 factorial design, using two iron mining substrates and inoculated and uninoculated plants with five repetitions. The seedlings received 25 g of the soil-inoculum mixture of Paraglomus occultum (C. Walker) JB Morton & D. Redecker and Claroideoglomus etunicatum (WN Becker & Gerd) C. Walker & A. Schüßler at the transplantation time to 17 dm3 pots. Stem diameter and leaf number were influenced only by the main effects of substrate and inoculation, while plant height was influenced by the interaction between substrate and inoculation. Inoculation with mycorrhizal fungi in Kielmeyera rubriflora ensures survival, species growth and root development on both iron mining substrates and is a suggested strategy for planting in areas degraded by iron mining.
