Hyptis suaveolens (L.) Point. (Lamiaceae) is a threat of biodiversity, environment and especially crops and pastures. This species has high propagation capacity in the environment. This study was initiated to contribute to the biological control of Hyptis suaveolens. To achieve this objective, morphological and physiological characteristics of seeds were realized. Mean length of 3.55 ± 0.18 mm, mean width of 2.20 ± 0.13 mm and mean thickness of 0.84 ± 0.08 mm were obtained. A purity rate of 94.4% ± 2.96 and mean number of 4850 seeds per gram were also obtained at morphological study. At physiological level, germination rate of 64.25% and percent water content of 10.2 ± 1.79% were obtained. Physical scarification reduced germination to 16% at micropylar level (CMI) and 31% at opposite side of micropyl (COM). Chemical scarification had virtually no germination rate. After three (3) months of storage, germination rate of 63.25% in refrigerated and 23.00% in ambient condition were observed. Change light and darkness was more favorable for better seed germination with 80% germination rate compared to 74.25% in light and 53.75% in darkness. These results could help effectively to combat this invasive plant.
