Soil properties in the foraging range of honeybees influence honey composition. We aimed to determine relationships between the antimicrobial properties of New Zealand mānuka () honey and elemental concentrations in the honey, plants, and soils. We analyzed soils, plants, and fresh mānuka honey samples from the Wairarapa region of New Zealand for the chemical elements and the antimicrobial activity of the honey as indicated by methylglyoxal (MGO) and dihydroxyacetone (DHA). There were significant negative correlations between honey MGO and the concentrations of Mn, Cu, Mg, S, Na, Ba, K, Zn, and Al. These elements may provide a low-cost means of assessing mānuka honey quality. For individual elements, except for K, there were no correlations between the honeys, plants, and soils. Soil nitrate concentrations were negatively correlated with concentrations of MGO and DHA in the honey, which implies that soil fertility may be a determiner of mānuka honey quality.
蜜蜂觅食范围内的土壤特性会影响蜂蜜的成分。我们旨在确定新西兰麦卢卡蜂蜜的抗菌特性与蜂蜜、植物和土壤中元素浓度之间的关系。我们分析了来自新西兰怀拉拉帕地区的土壤、植物和新鲜麦卢卡蜂蜜样本中的化学元素，以及由甲基乙二醛（MGO）和二羟基丙酮（DHA）表示的蜂蜜抗菌活性。蜂蜜中的MGO与锰、铜、镁、硫、钠、钡、钾、锌和铝的浓度之间存在显著的负相关。这些元素可能提供一种低成本的评估麦卢卡蜂蜜质量的方法。对于单个元素，除了钾之外，蜂蜜、植物和土壤之间没有相关性。土壤硝酸盐浓度与蜂蜜中MGO和DHA的浓度呈负相关，这意味着土壤肥力可能是麦卢卡蜂蜜质量的一个决定因素。
