摘要：以1~5年生党参为试材,以划取样方观察生育周期,采用‘S’取样法对各小区随机选取15株党参进行测产;参照《国际种子检验规程》对党参发芽率、发芽势、发芽指数进行测定;以60d党参苗生物性状为指标,评价党参种子的育苗特性。结果表明:1~3年生党参随着生长年限的延长,种子生育周期缩短;种子产量和质量与生长年限整体呈正相关。3年生党参种子各指标均达到峰值,4~5年生党参种子各指标和3年生党参持平,所产种子以棕黑色为主,单株产种量在10g左右,发芽率均达到90%以上,60d存苗率均在80%以上。大田生产中,育种党参以3年生(移栽次年)为宜。
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.
