采石业是支持人类基础设施的重要行业，但它对人类健康，环境和植物群落有负面影响。在日本杉岛（Sugashima）的蛇纹石采石场的情况下，使用本地植物的快速补救是必要的，以恢复蛇纹石生态系统。根据我们的前期工作，我们揭示了日本野生百里香（ThquinquecostatusCelak）的高适应性。蛇纹岩地区的恶劣环境，我们希望利用这种植物进行植被重建。然而，与已被用于重新植被实验的经过充分调查的欧洲百里香相比，关于日本百里香的基本信息极为有限。这项工作的目的是确定从日本不同地区收集的野生百里香的植物功能性状，并测试其潜在的蛇纹石采石场土壤植被。我们收集了四种类型的野生百里香杉岛和其他地区的蛇纹岩，石灰质，凝灰岩角砾岩土壤，并揭示了品种的差异，叶的形式，分支模式，花，开花季节，种子形成能力，种子发芽率。蛇纹石和石灰质地区的百里香可以在蛇纹石采石场的土壤上生长，少量的植物能够覆盖实验区。在所调查的日本百里香中，杉岛百里香具有最长的分枝，并且通过形成许多分枝而迅速传播。这些数据表明，日本百里香，特别是杉岛百里香，有很好的潜力，重新植被的蛇纹石采石场。
Quarrying is an important industry that supports human infrastructure, but it has negative effects on human health, environments, and plant communities. In the case of the serpentine quarry on Sugashima Island (Sugashima), Japan, rapid remediation using native plants is necessary to restore the serpentine ecosystem. According to our previous work, we revealed high adaptability of Japanese wild thyme (Thymus quinquecostatusCelak.) to the severe environment of serpentine areas, and we desired to utilize this species for revegetation. However, basic information on Japanese thyme was extremely limited, in comparison with well-investigated European thymes that have been used for revegetation experiments. The aims of this work were to identify the plant functional traits of wild thymes collected from different areas of Japan and to test their potential for revegetation of serpentine quarry soil. We collected four types of wild thyme from Sugashima and other areas of serpentine, calcareous, and tuff breccia soil, and revealed varietal differences in leaf form, branching patterns, flowers, and also blooming season, seed formation ability, and seed germination percentages. Thymes from serpentine and calcareous areas could grow on soil of the serpentine quarry, and a small number of plants were able to cover the experimental plots. Among the Japanese thymes investigated, Sugashima thyme had the longest branches, and spread rapidly by forming many branches. These data suggest that Japanese thymes, especially Sugashima thyme, have good potential for revegetation of serpentine quarries.
