| description | Macroptilium martii Benth. is a native grass species of the Caatinga, used in the feeding of cattle and goats during dry periods. This study aimed to characterize the fruit and seeds, as well as evaluating the germination of the seeds of M. martii subjected to different methods of scarification. For the characterization of the seeds was carried out using biometrics a random sample of 100 seeds and 100 fruits. Mass, length, width and thickness of fruits and seeds, and number of seeds per fruit were evaluated. With and without lopping: monitoring the soaking curve using two treatments: with and without lopping. Twelve pregerminative to assess seed dormancy treatments were used: control, coating, soaking for 12, 24 and 48 hours, warm to 80 °C for 3, 6 and 12 minutes and sulfuric acid (H2SO4) for 3, 6 water 12 minutes. The seeds were germinated as substrate type germitest paper towel. The design was completely randomized with four replications of 25 seeds each. The data were submitted to Tukey test at 5% probability. The seeds of M. martii have low variation for biometric features. Furthermore, seeds respond to standard soaking phase, being verified by the dormancy coating impermeable. The most appropriate method for breaking dormancy is blunt on the side opposite the micropyle, it provides the best conditions for seed germination. |
