    This study was conducted at the Quinta Tunducama Forest nursery for native plants, in the parish of Belisario Quevedo, province of Cotopaxi, Ecuador, with the objective of determining the most efficient propagation method for Eugenia myrtifolia among three techniques: seeds, cuttings and stakes. The research focused on evaluating the germination rate, the number of shoots and their length under controlled conditions during a period of 60 days. 720 vegetative units were used, distributed equally between the three propagation methods, with 240 units for each technique. Monitoring was carried out daily, recording the key variables for each treatment. After 30 days of the experiment, the results showed that propagation by cuttings was the most effective, with 67.5% success (162 germinated cuttings), while no germination was observed in the seeds during this period. The stakes also demonstrated an acceptable performance, with 20% germination (48 germinated cuttings). However, at 60 days, the seed propagation method had a 90% success rate (216 germinated seeds), outperforming the other two methods. Cuttings achieved 81.7% germination (196 germinated cuttings), as did stakes, which achieved the same percentage of success (196 germinated cuttings). In terms of the number of shoots, cuttings produced an average of 8 shoots per unit, while stakes generated 6 shoots per unit. These results confirm that, although the cutting method is more efficient in the early stages of propagation, the seed method is superior in the long term in terms of germination rate. Seeds, under suitable environmental conditions, can break their dormancy and develop a robust root system. Likewise, the importance of climatic conditions and the use of suitable techniques to accelerate the propagation process in cuttings and stakes is highlighted. In conclusion, the research provides valuable information to improve Eugenia myrtifolia propagation practices in forest nurseries, promoting sustainability and efficiency in native plant production. The choice of propagation method should depend on the needs of the project and the time available, with seeds being more suitable for long-term projects and cuttings for faster results.
