Abstract:
Background and Objective: Nowadays, most of the medicinal plants can no longer be found in the proximity of rural and urban areas and even in the far away forests as before due to deforestation and progressive desertification. Therefore, the objective of this study was to investigate and find out the best possible methods (hormonal regulator, chemicals and hot water) of breaking dormancy in Senna alata. Materials and Methods: The seeds were subjected to different methods and durations of exposure to break the dormancy and enhance germination. The seeds were treated with 85 mg of GA3 and 350 mg of GA3, 98% concentrated H2SO4, 70.5% HNO3 and100°C hot water, for 10 and 20 min and were arranged in a completely randomized block design with 3 replications. Results: The experimental results demonstrated that hot water and 98% concentrated H2SO4 for 10 and 20 min were the most effective treatments for augmenting seed germination (83 and 93; 76.67 and 93.33%, respectively), followed by GA3 for 10 and 20 min (49.83 and 46.67%). Conclusion: Hot water and H2SO4 treatments are highly recommended to break seed dormancy in Senna alata.
