Abstract: (140 Views)
Background: Salvia spinosa L., a valuable medicinal species with antioxidant and anti-inflammatory properties, requires sustainable cultivation methods for pharmaceutical applications. This study investigated photothermal factors affecting seed germination indices to optimize domestication protocols. Objectives: The primary aims were to evaluate the effects of seed age, light conditions, and temperature on key germination indices and seedling vigor, and to establish optimal cultivation protocols for controlled growth. Methods: The experiment followed a completely randomized design with 10 treatments (combining seed age, temperature, and light factors) and three replicates. Measured parameters included final germination percentage, germination index, mean daily germination, germination speed, and seedling vigor indices. Data were analyzed using Duncan’s multiple range test and orthogonal comparisons. Results: The highest germination rate (100%) was observed in aged seeds under warm temperatures and a light cycle. In contrast, the optimal treatment (No. 6: aged seeds + lab temperature [12°C night/20°C Day] + lab ambient light) achieved a balanced germination rate (85%) and robust seedling vigor. Absolute darkness was identified as the primary limiting factor for germination. Conclusion: Treatment No. 6 is recommended as the optimal seed germination protocol for domesticating of this plant. These findings represent a significant step toward sustainable cultivation for pharmaceutical use, reducing reliance on wild harvesting.
