Science: Seed Taming
Recalcitrant seeds are not only desiccation-sensitive, but also metabolically active. In contrast, orthodox seeds, owing to their dry state, are metabolically quiescent. Lowering the water content to a level that would preclude germination but facilitate vital metabolism has been suggested as a way to extend the life-span of recalcitrant seeds in hydrated storage. However, Daniel Côme and Françoise Corbineau of the Université Pierre et Marie Curie in Paris, and we, have independently shown that this practice of partial dehydration curtails the seeds' storage life-span.…
