摘要
玉米作为食物来源、饲料和工业原料,在全球发挥着重要作用。然而,玉米受到产毒真菌(主要是禾谷镰刀菌、疣孢镰刀菌和黄曲霉)的影响,质量受到损害。本研究于 2022 年和 2023 年在匈牙利德布勒森大学拉托凯普长期研究基地进行,调查了不同氮肥施用量(0、90 和 150 Kgha-1 N)对三(3)种玉米杂交种籽粒中霉菌毒素污染(DON vs. FB vs. AFB1)的影响:DKC4590(耐受)、GKT376(敏感)和 P9610(未确定)。结果表明,氮肥和玉米基因型对霉菌毒素含量有明显影响(p = 0.05)。单氮的影响是复杂的,没有明确的趋势,这与所选杂交种的抗性优越性相反。氮肥的增加与较高的 DON 产量有关,而杂交种的选择则在抗霉菌毒素方面表现出更明显的趋势。因此,为了实现产量最大化和霉菌毒素污染最小化,未来的研究应侧重于优化氮肥施用量和抗性育种,以平衡产量和霉菌毒素管理。这些结果表明,虽然氮肥对最大限度地提高产量至关重要,但选择抗性较低的玉米杂交种对最大限度地减少霉菌毒素污染仍然至关重要。
Aspergillus and Fusarium Mycotoxin Contamination in Maize (Zea mays L.): The Interplay of Nitrogen Fertilization and Hybrids Selection
Maize plays a significant global role as a food source, feed, and as a raw material in industry. However, it is affected by toxin-producing fungi, mainly Fusarium graminearum, Fusarium verticillioides, and Aspergillus flavus, which compromise its quality. This study, conducted in 2022 and 2023 at the Látókép long-term research site of the University of Debrecen, Hungary, investigated the effects of different nitrogen fertilization rates (0, 90 and 150 Kgha−1 N) on mycotoxin contamination (DON vs. FB vs. AFB1) in the kernels of three (3) maize hybrids: DKC4590 (tolerant), GKT376 (sensitive), and P9610 (undefined). The results showed a significant (p = 0.05) influence of nitrogen fertilization and maize genotype on mycotoxin levels. Sole nitrogen impacts were complex and did not define a clear trend, contrary to the hybrids selected, which followed superiority to resistance. Increased nitrogen fertilization was associated with higher DON production, while hybrid selection demonstrated a clearer trend in resistance to mycotoxins. Therefore, to maximize yield and minimize mycotoxin contamination., future research should focus on optimizing nitrogen application rates and breeding for resistance to balance yield and mycotoxin management. These results suggest that while nitrogen fertilization is crucial for maximizing yield, selecting less susceptible maize hybrids remains vital for minimizing mycotoxin contamination.
