引种驯化对药用芍药产量和质量的研究

Studies on yield and quality of medicinal Paeonia lactiflora Pall. by introduction and domestication

采用单因素对比试验,通过测定芍药药材个体质量、水分、浸出物及芍药苷含量等指标,揭示引种驯化对药用芍药产量和质量的影响,探寻药用芍药最佳引种品种。结果表明,甘肃野生引种驯化的芍药根粗(16.52 mm)且长(21.67 cm)、芽粉色,芽数最多(15.67个)且最长(25.25 cm),侧根数较少,根腐病显著降低,芍药苷含量分别高于山东和安徽的芍药品种0.77%和0.13%。同产地的不同芍药品种引种驯化后,野生的药用芍药个体质量优异,品质好,其中野生品种的芍药苷含量高于改良品种的芍药苷含量0.26%,高于栽培品种的芍药苷0.76%。说明引种驯化适宜丰富本地的芍药品种,建议规范化生产,提倡同省引种驯化的药材个体质量优异,芍药苷含量高。

To reveal the difference of introduction and domestication of medicinal paeoniflorin and and explore the suitable local fine medicinal Paeonia lactiflora Pall. varieties by single factor contrast test. The contrast experiment of introduction and domestication was conducted to measure individual quality index,water content,extract and content of Paeoniflorin. The results showed that the roots of Gansu wild Paeonia lactiflora were thick(16.52 mm) and long(21.67 cm),the number of buds was the most(15.67) and the longest(25.25 cm),the number of lateral roots was less,the root rot decreased significantly,and the content of paeoniflorin was higher 0.77% and 0.13% than that of Shandong and Anhui. The results showed that introduction and domestication were suitable for enriching local peony varieties and suggested that standardized production should promote the excellent individual quality and high content of paeoniflorin.
