摘　　要：目的:探索贮藏条件对延胡索种子发育过程的影响。方法:采集野生延胡索种子在不同条件下贮藏,对其胚的形成过程跟踪观察,测定它们的发芽率并进行对比。结果:不同的贮藏条件对延胡索种子的发育有不同影响,层积后种子发芽率最高;而干藏种子完全丧失生命力;恒温贮藏培养的种子发芽率极低。切片显示,只有经过层积处理的种子才能形成完整的胚。结论:延胡索种子为胚未完全发育及需生理后熟作用的种子,季节性、年度性很强。Objective：To explore the influence of the storage conditions on the seed development of Corydalis yanhusuo.Methods：The embryo formation process of the wild Corydalis yanhusuo was observed,and the germination rate of wild Corydalis yan husuo seeds stored under different conditions was measured.Results：The seed development of the wild Corydalis yanhusuo depended on the storage conditions.The seeds subjected to stratification had the highest germination percentage.Those stored in dry conditions would lose the vitality completely.The seeds in isothermal storage had very low germination rates.As revealed by slices,only the seeds after stratification treatment had the ability to form a complete embryo.Conclusion：The Corydalis yanhusuo seed is a kind of seed without fully developed embryo,and needs further after-ripening for its development.Its vitality has a great seasonal and annual dependence.
