          [摘要]通過廣泛收集產自甘肅省渭源縣、漳縣、岷縣、宕昌縣、隴西縣等地黨參種苗30份,測定其根長、根粗、單根重,然后K聚類分析,依據聚類結果將種苗劃分為3個等級,以不同等級為處理進行田間試驗,研究不同等級黨參種苗與藥材產量及質量的關系,為制定黨參種苗質量標準提供依據。研究結果顯示,一級苗出苗最快,產量最高,且顯著的高于二級苗和三級苗(P<0.05);一級苗炔苷含量最高,顯著高于三級苗(P<0.05);三級苗多糖含量最高,顯著高于二級苗和一級苗(P<0.05)。因此從黨參藥材產量、質量及投入成本綜合分析,黨參移栽應選擇根長>15.6 cm,根粗>2.7 mm,單根重>0.56 g的種苗為宜。

          [Abstract]The study is aimed to research the relationship between the seedling grade ofCodonopsis pilosula and yield and quality of medicinal materials, so as to provide basis for establishing seedling standard. Thirty seedlings ofC. pilosula were collected from the main production areas in Gansu province, such as Weiyuan, Minxian, Zhangxian, Dangchang and Longxi, root length and diameter and weight of all the samples were measured. According to the clustering results, seedlings were divided into 3 levels, and field experiments were conducted with three levels seedling, yield and quality were tested in laboratory. Results have showed that emergence of grades 1 was faster than that of grades 2 and 3. Yield of grades 1 was significantly higher than that of grades 2 and 3 (P<0.05). Propargyl glycoside content of grades 1 was the highest, and significantly higher than that of grades 3. Polysaccharide content of grades 3 was the highest and significantly higher than that of grades 1 and 2 (P<0.05). So considering yield, quality and investment cost of C. pilosula, planting seedlings ofC. pilosula should select that root length>15.6 cm, root diameter>2.7 mm, root weight>0.56 g.

          黨參Codonopsis pilosula(Franch.)Nannf.為桔?泣h參屬多年生草質藤本植物,以其色白、形直、質細、肉實和藥效穩(wěn)定者為佳。具有補中益氣,健脾益肺的功效[1]。近年來,關于黨參研究主要集中在栽培技術[2]、品種選育[3]、不同產區(qū)質量比較[4-7]、藥材貯藏加工[8-11]等方面。黨參除應用于醫(yī)藥衛(wèi)生外,更被廣泛應用于保健、藥膳等領域[12],需求量逐年增加。因此規(guī)范黨參種苗市場,制定黨參種苗質量標準迫在眉睫。鑒于此,本研究以國家基本藥物所需中藥材種子種苗繁育基地建設為契機,通過不同產區(qū)黨參種苗質量指標(根長、根粗、單根重等)測定—K聚類分級—田間試驗,對不同等級種苗所產藥材產量及構成因素、藥效成分等做定量比較分析,為制定黨參種苗質量標準奠定基礎,也對規(guī)范黨參種苗市場提供參考。
