对多年生野生延胡索的生长状态做跟踪观察，结果表明，其繁殖新块茎的方式有两种。双生块茎的出现随生长年限的增加而增加，但是此种特性并非固定遗传。新生芽点的产生通常在母块茎靠上端的部分。 A follow-up observation was made on the growth status of perennial wild Corydalis, and the results showed that there are two ways to propagate new tubers. The emergence of twin tubers increases with the increase of the growth period, but this characteristic is not fixed genetic. The budding buds are usually produced on the upper part of the mother’s tuber.
