Valeriana carnosa is an important medicinal herb in the Patagonian popular medicine. The underground parts of this native species are used for the preparation of various formulations in the traditional health system for treatment of hepatic, circulatory, urinary and digestive disorders as well as having analgesic, anti-inflammatory and anti-depressive properties. Although V. carnosa is one of the most used medicinal plants in Patagonia, currently the raw material (roots and rhizomes) is obtained from natural populations. The aim of this study was to generate novel tools for stimulating in situ cultivation of V. carnosa to improve the sustainable management of this phytomedicinal resource and the quality control of its commercial plant material. The agamic multiplication of V. carnosa was tested, applying different concentrations of indole-3-butyric acid (IBA), α-naphthaleneacetic acid (NAA) and a commercial rooting mix product (containing NAA 3000 ppm) in leafless and leafy cuttings. The application of NAA was more effective than IBA to stimulate roots development in stem cuttings. The results indicate that leafy cuttings treated with NAA (1000 ppm and 3000 ppm) give 40–60 propagules from each adult mother plant, ensuring significantly (p < 0.05) higher rooting percentages. To determine the effect of the phytohormones application on the root system development, five morphological root variables were analyzed by non-parametric analysis of variance (Kruskal–Wallis) at P-value (0.05) significance levels and differences were observed depending on the treatment used. In this study we propose: 1- an efficient and inexpensive protocol for vegetative multiplication, and 2- provide information for in situ cultivation of V. carnosa in Patagonia.

缬草是巴塔哥尼亚流行医学中的重要草药。该天然物种的地下部分用于制备传统保健系统中的各种制剂，以治疗肝，循环，泌尿和消化系统疾病，并具有止痛，抗炎和抗抑郁作用。尽管卡诺萨弧菌是巴塔哥尼亚最常用的药用植物之一，但目前的原料（根和根茎）是从自然种群中获得的。这项研究的目的是生成新的工具来刺激现场的种植五carnosa改善这种植物药资源的可持续管理及其商业植物材料的质量控制。的无性繁殖五carnosa在无叶和多叶插条中使用不同浓度的吲哚-3-丁酸（IBA），α-萘乙酸（NAA）和商业生根混合产品（包含NAA 3000 ppm）进行了测试。NAA的应用比IBA在刺激stimulate插中的根部发育方面更有效。结果表明，用NAA（1000 ppm和3000 ppm）处理过的多叶插穗从每株成年母本植物中繁殖出40-60株繁殖体，确保显着（p <0.05）的生根率。为了确定植物激素的施用对根系发育的影响，通过非参数方差分析（Kruskal–Wallis）以P值（0.05）显着性水平分析了五个形态学根变量，并观察了差异，具体取决于所使用的处理方法。在这项研究中，我们建议：巴塔哥尼亚V. carnosa的原位栽培。
