Herbs used in medicine should be grown under controlled and standardized conditions. Agricultural practices often induce changes to soil pH, which may affect migration of heavy metals in the environment, their accumulation in plant tissues and the concentration of medicinal ingredients. The aim of this work was to assess the influence of various soil pH on the biological parameters and uptake of manganese, copper and zinc by basil, dandelion and lemon balm. The soil analysis covered pH, organic matter content, bioavailable and total forms of investigated metals in soil. In plants cultivated in soil at pH covering the range 4.7-8.5 the concentrations of Mn, Cu and Zn were analyzed. Their mobility and availability were assessed by bioaccumulation factors, translocation factors and transfer coefficients. The seed germination and subsequent herbs growth were strongly dependent on soil pH for all investigated plant species. Photosynthetic efficiency at different pHs was positively correlated with uptake of Cu and Mn while Zn behaved in a more random way.
中药材的种植应当在可控且标准化的条件下进行。农业实践往往会导致土壤 pH 值发生变化，而这可能会影响环境中重金属的迁移、它们在植物组织中的积累以及药用成分的浓度。本研究旨在评估不同土壤 pH 值对罗勒、蒲公英和柠檬香蜂草的生物参数以及锰、铜和锌吸收的影响。土壤分析涵盖了 pH 值、土壤中有机质含量、生物可利用和总形式的调查金属。在 pH 值范围为 4.7-8.5 的土壤中种植的植物中分析了 Mn、Cu 和 Zn 的浓度。通过生物累积因子、迁移因子和转移系数评估了它们的迁移性和可用性。对于所有受调查的植物物种，种子的发芽和随后的草药生长强烈依赖于土壤 pH 值。不同 pH 值下的光合效率与 Cu 和 Mn 的吸收呈正相关，而 Zn 的行为则更为随机。
