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。
Taking 1 to 5 years old Codonopsis pilosula as test material, the sampling period was used to observe the reproductive cycle. The 15 samples of Codonopsis pilosula were randomly selected in each plot for the test. The “International Seed Testing Protocol” was used to measure the germination rate, , Germination index were measured; 60d Codonopsis seedling biological indicators as an indicator to evaluate the characteristics of Codonopsis seedling. The results showed that the growth period of 1-3 years old Codonopsis pilosula was shortened and the seed production period was shortened. The yield and quality of seeds were positively correlated with the growth period. The indexes of 3-year-old Codonopsis pilosula reached the peak, the indexes of 4 ~ 5-year-old Codonopsis pilosula and 3-year-old Codonopsis were the same, the seeds of the 3-year-old Codonopsis lanceolata were mainly brown and black, the yield per plant was about 10g and the germination rate reached more than 90% 60d deposit rate are more than 80%. Daejeon production, breeding Codonopsis 3 years (transplanted next year) is appropriate.
