GERMINATIVE PERFORMANCE OF MULUNGÚ SEEDS (Ormosia grossa Rudd) AFTER DORMANCY OVERCOMING

ABSTRACT Ormosia grossa Rudd is an Amazonian species that presents bicolor seeds, allowing its exploration for handicraft and decoration making. This paper aimed to analyze the influence of different methods overcome dormancy on germinative performance seeds. To conduct experiment, following treatments were established: T1= scarification with 80-grit sandpaper water immersion at room temperature 24 hours; T2= puncturing T3= sandpaper; T4= puncturing; T5= in heated 80 ºC five minutes, T6= Control - seeds without any treatment. The germinate slowly irregularly. Depending treatment, germination started between 10 32 days and, if there no adequate pre-germinative treatment dormancy, it can exceed such time. phytomass seedling lengths superior T1 T2 treatments. by abrasiveness are efficient thus increasing speed (3.76 3.12) percentage (98% 96%) after ten days. control was 0.01 (IVG), 37%. Therefore, recommended method followed seed imbibition hours, as provides best germination.
