Abstract

This study aimed to identify the most effective physical method for overcoming dormancy of Enterolobium contortisiliquum (Vell.) Morong seeds. (monkfish), which have a high level of dormancy and low germination, which can hinder seedling production. A completely randomized design was used consisting of six treatments, each with 40 replications, sown in plastic bags with dimensions of 12 x 20 cm containing substrate mixture of soil, sand and cattle manure, and daily watering to maintain the substrate humidity. The treatments consisted of: T1 = Witness; T2 = Mechanical scarification; T3 = Mechanical scarification with water immersion for 6 hours; T4 = Cutting by pruning shears; T5 = Cut by pruning shears immersed in water for 6 hours; T6 = Immersion in boiling water until cooled to room temperature. Germination percentage, germination speed index (IVG) and average time to germination (GMT) were evaluated. The results allowed us to infer that the T4 treatment was the treatment that presented the highest efficiency in overcoming tamboril seed dormancy considering that it is a simple method, has low cost/benefit and operational ease.
