title: [Influence of storage conditions on the seed development of Corydalis yanhusuo].
abstract: 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 yanhusuo 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.
  
  
  CONCLUSIONS
  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.
