This project aims to transform existing propagation methods for rushes and sedges (recalcitrant, but key colonizer species) for restoring critical biodiversity in Australian mine-site restoration. This will be achieved through the process of somatic embryogenesis and will result in cost effective and efficient mass propagation. Significantly, this somatic embryogenesis research will provide the springboard for development of seed analogues (coated, desiccated somatic embryos) with subsequent economies from bypassing more costly nursery production of whole plants, utilizing existing infrastructure for direct seeding of restoration sites, and reducing dependence on dwindling reserves of wild-harvested seed.

该项目旨在改变灯芯草和莎草（顽固的，但关键的殖民物种）现有的繁殖方法，以恢复澳大利亚矿区恢复的关键生物多样性。这将通过体细胞胚胎发生过程实现，并将导致成本效益和高效的大规模繁殖。值得注意的是，这项体细胞胚胎发生研究将为种子类似物（被包衣的干燥体细胞胚胎）的发展提供跳板，从而避免了更昂贵的整个植物苗圃生产，利用现有的基础设施直接播种恢复地点，减少对日益减少的野生收获种子储备的依赖。
