一年生延胡索块茎的研究

Studies on Tuber and First Age Plants of Yanhusuo(Gorydalis yanhusuo)

采集野生延胡索Corydalisyanhusuo的种子，在苗圃中播种，栽培，发现其出苗率与种子的大小及成熟度有关。对其1年生块茎的生长形态及内部结构进行观察，其虽为双子叶植物，但出苗时仅1枚子叶，皮层有分泌组织，形成层发达，而木质部、韧皮都构不发达。

Corydalis yanhusuo W. T. Wang ex Z. Y. Su et C. Y. Wu is an aperennial herb which grous wild in Anhui Province. The tuber of the plants is used as an anodyne. Cultivation of the plant with seeds obtained from the wild was carried out in our nursery breeding house. Results showed that the emergence rate depends upon the size and ripeness of the seed. Although it is a dicotyledon,yet its seedling showed only a single cotyledon. Secretary tissues could be found in its cuticular layer. Cambium was well developed but both xylem and phleom were not well developed
