Abstract

The present research aimed to evaluate pre-germinating treatments in order to overcome the dormancy of seeds of four (Leguminoseae) native forest species of Brasilian ";Mata Atlântica";. The experiment was carried out in greenhouse at Centro de Ciências Agrárias of Universidade Federal da Paraíba, at Areia-PB, Brazil. ";Jatobá";, ";guapuruvu";, ";orelha-de-negro"; and ";madeira nova"; seeds were subjected to the following treatments: T1- lateral scarification,T2 - lateral scarification plus imbibition for 24 hours at room temperature; T3 - immersion in water at 50°C until cool; T4 - immersion in water at 60°C until cool; T5 - immersion in distilled water (24 hours) at room temperature; T6- control. Sowing was done in trays using sand substrate. The traits evaluated were emergence and index of emergence speed. The results obtained indicate that ";jatobá"; seeds subjected to scarification followed by imbibition proved to produce more vigorous seedlings. Scarification without imbibition may be recomended as a pre-germinating treatment in ";orelha-de-negro"; seeds. Scarification followed or not by imbibition in water was also efficient in breaking the dormancy of ";guapuruvu"; seeds. However, no treatment used was efficient in overcoming the dormancy of ";madeira nova"; seeds.
