In this study, the phytotoxic effects caused by the exposure to five different concentrations of two veterinary antibiotics (Tylosin, and Enrofloxacin) that are commonly used for the treatment of farm animals as antibacterial agents were considered. The impact of antibiotic residues was evaluated on the germination percentage, accumulation, and seedling elongation of the barley seeds using Petri dishes under controlled environmental conditions. The treatments were distributed randomly using Completely Randomized Design (CRD). The germination percentage was significantly inhibited with the increasing Enrofloxacin dose concentrations, while, it was to some extent on the contrary in the case of Tylosin, where seed germination was enhanced as a result of increasing Tylosin concentrations. Liquid chromatography-tandem mass spectrometry LC/MS-MS was used to detect and quantify the uptake dosage after drying and extracting the antibiotic compounds from the seedling.
在本研究中，考虑了暴露于两种常用作农场动物抗菌剂的兽用抗生素（泰乐菌素和恩诺沙星）的五种不同浓度所引起的植物毒性效应。在可控环境条件下，使用培养皿评估抗生素残留对大麦种子发芽率、积累量和幼苗伸长的影响。采用完全随机设计（CRD）随机分配处理。随着恩诺沙星剂量浓度的增加，发芽率受到显著抑制，而对于泰乐菌素则在一定程度上相反，随着泰乐菌素浓度的增加种子发芽得到增强。采用液相色谱 - 串联质谱法（LC/MS - MS）在干燥并从幼苗中提取抗生素化合物后检测和定量吸收剂量。
