摘要

Many plants disperse their seeds via a process so explosive that chemical bonds are broken, releasing stored elastic energy and creating cracks in the seed pods. Robert Deegan (pp. 5166-5169) studied how dulifera, a highly invasive species, can launch its seeds with speeds up to 4 m/s despite the highly dissipative process of crack formation. The plant's seed pod consists of 5-10 seeds held within a shell comprised of five elongated segments or valves.
