Abstract:

The first to fifth year plants of Codonopsis pilosula（Franch.） Nannf.were taken as the test materials.The seeds reproductive cycles was observed in the specified areas.Fifteen C.pilosula（Franch.） Nannf. plants were selected by the ‘S’ sampling method in the each experimental plot for measuring yield.The germination rate,germination potential,germination index of C.pilosula（Franch.） Nannf. were measured by the methods with reference to International Seed Test Agreement.The cultivation seedling characteristics of the seeds of C.pilosula（Franch.） Nannf.were evaluated with the biological characteristics of 60 days seedling as the indicators.The results showed that from the first year to the third year in the growing process of C.pilosula（Franch.） Nannf.,the seeds reproductive cycle shortened with the increase of the growing year.The indexes of yield and quality of seeds were positively correlated with the growing year.And the each index of seeds reached the peak values in the third year,and kept the close level in the fourth and fifth year.The seeds obtained from the third to fifth year plants mostly were brownish black,the yield of single plant was about 10 g.The germination rate of the seeds was above 90%.The 60 days seedling survival rate was above 80%.In the field production,the best harvest year of seeds was the third year.
