Objective: The objective was to evaluate different scarification treatments to improve germination in chepil seeds (Crotalaria longirostrata Hook. & Arn.). Design/Methodology/Approach: The study was established in the School of Veterinary Medicine and Zootechnics N. 2 of the Universidad Autónoma de Guerrero. The chepil seeds were weighed and counted; 2 experiments were established through a CRD with 4 treatments of 4 repetitions each. Imbibition and germination were evaluated. The data were analyzed with the statistical software package SAS® 9.0.Results: The use of water at different temperatures and times presented positive results in imbibition and increased the germination percentages. The treatment with water at 100 °C until cooling reached a germination of 80%, and the control of 12.3%.Study Limitations/Implications: Chepil is a wild species that has seeds with physical dormancy, which is something that requires more research in order to accelerate and increase the germination percentages. Findings/Conclusions: The imbibition and germination was affected by the treatments applied. Chepil seeds presented physical or superficial dormancy that may be eliminated with the use of heat treatments; however, evaluations still need to be performed to accelerate and find a higher percentage of germination
