摘要:
为了分析可能影响玉米种子发芽率测定结果的污染性微生物种类,对广东省种子质量监督检验工作中抽检的8份玉米种子样品在萌芽过程中产生的发霉状污染物进行高通量测序与微生物种类鉴定。结果表明,这些样品在发芽率测定试验中产生的污染性细菌来自11门、22纲、36目、62科、119属,其中变形菌门(Proteobacteria)为优势门类,其平均相对丰度为76.8%,γ-变形菌纲(Gammaproteobacteria)为纲水平上的优势类群(占60.0%),而假单胞菌属(Pseudomonas)、泛菌属(Pantoea)、金黄杆菌属(Chryseobacterium)、鞘氨醇杆菌属(Sphingobacterium)、伯克氏菌属(Burkholderia)和不动杆菌属(Acinetobacter)为平均相对丰度较高的6属(占6.9%~24.1%)。上述玉米样品产生的污染性真菌属于3门、16纲、27目、53科、71属、93种,其中子囊菌门(Ascomycota)、毛霉门(Mucoromycota)的平均相对丰度分别为57.67%、41.59%,粪壳菌纲(Sordariomycetes)、毛霉纲(Mucoromycetes)与散囊菌纲(Eurotiomycetes)在不同污染物样品中为优势类群(占56%~98%),根霉属(Rhizopus)、赤霉属(Gibberella)、木霉属(Trichoderma)、青霉属(Penicillium)、篮状菌属(Talaromyces)为平均相对丰度最高的5个属,而少根根霉(R. arrhizus)、棘孢木霉(Trichoderma asperellum)、藤仓赤霉(G. fujikuroi)、草酸青霉(P. oxalicum)与当归蓝状菌(Talaromyces angelicus)为不同样品中的优势种。研究结果可为玉米种子检验试验的质量控制及玉米种传病害的预防提供有益参考。
