摘要: 以大田栽培板蓝根(Isatidis Radix)的叶鲜重、根鲜重、主根长、芦径、根中径和叶片数为候选指标,通过相关性分析、主成分分析及聚类分析,选定根鲜重、芦径、根中径和主根长共4个关键分级指标,并据此制定板蓝根制种母株的3级分级标准,具体如下:Ⅰ级,根鲜重≥189 g,芦径≥2.5 cm,根中径≥2.0 cm,主根长≥30 cm;Ⅱ级,189 g>根鲜重≥87 g,2.5 cm>芦径≥1.8 cm,2.0 cm>根中径≥1.7 cm,主根长≥30 cm;Ⅲ级,87 g>根鲜重≥58 g,1.8 cm>芦径≥1.4 cm,1.7 cm>根中径≥1.4 cm,主根长≥30 cm。品质分析表明,各等级试材的(R,S)-告依春含量和醇溶性浸出物含量均符合《中华人民共和国药典》标准,其中醇溶性浸出物含量表现突出。依据该标准,结合板蓝根大田生产采收工序进行优良单株选择,将选出的优株群体作为制种母株用于板蓝根种子生产。

Abstract: Using the fresh weight of leaves, fresh weight of roots, main root length, rhizome diameter, middle root diameter, and number of leaves as candidate indicators, four key grading indices:Fresh root weight, rhizome diameter, middle root diameter, and main root length,were identified for Isatidis Radix mother plants used for seed production through correlation analysis, principal component analysis, and cluster analysis. Based on these findings, a three-grade classification standard for mother plants was established as follows: Grade Ⅰ: fresh root weight ≥ 189 g, rhizome diameter ≥ 2.5 cm, middle root diameter ≥ 2.0 cm, and main root length ≥ 30 cm; Grade Ⅱ: 189 g > fresh root weight ≥ 87 g, 2.5 cm > rhizome diameter ≥ 1.8 cm, 2.0 cm > middle root diameter ≥ 1.7 cm, and main root length ≥ 30 cm; Grade Ⅲ: 87 g > fresh root weight ≥ 58 g, 1.8 cm > rhizome diameter ≥ 1.4 cm, 1.7 cm > middle root diameter ≥ 1.4 cm, and main root length ≥ 30 cm. Quality analysis showed that the contents of (R,S)-goitrin and ethanol-soluble extracts in all graded samples met the standards specified in the Pharmacopoeia of the People’s Republic of China, with ethanol-soluble extract content being particularly prominent. According to this standard, superior individual plants were selected during the field harvesting process of Isatidis Radix production, and the selected elite plant population was used as mother plants for seed production.
