摘　　要： 产生顽拗性种子的植物通常生存在易于比较迅速形成幼苗的生境。须拗性种子在发育中期获得萌发能力，不经历成熟脱水，脱落后能继续萌发。种子中的贮藏物质和植物生长调节物质的变化有利于种子萌发。 Plants which produce recalcitrant seeds generally exist in the environment where seedlings were more easilyand rapidly formed. Recalcitrant seeds could acquire germinability during their median period of development, andcouldn't undergo maturation drying, and could continue to germinate after shedding. The changes of stored reserves and plant growth regulators in recalcitrant seeds were favourable for seed germination.
