We had been conducted cultivation of Corydalis ambigua CHAM, et SCHLECHT. using this seeds and tubers. In the previous papers, we reported some findings of seed germination stage, the first age plant, the quantitative determination method of major tertiary alkaloids (corybulbine, corydaline and cavidine) and processing of cultivated species. In this time, the influence of seed weight upon germination rate and forming of the first age tuber, and the renewal from the first age plant to the second age plant were investigated. As a result that, germination rate of ripe seeds were in direct proportion to the seed weight, but unripe seeds did not germination at all. The weight of the first age tuber was seriously affected by the seed weight. It was found that the second age tuber was not simply originated from the thickening growth of first age tuber, but it was renewed by new bud that was made in the first age tuber. The second age plant formed a new tuber while the terrestial part (leaves) was living, and its tuber grow up to about 5.2 times (190 mg) as weight in comparison with the first age tuber.
