This study aimed to determine the ability of Fusarium verticillioides in developing mechanisms to counteract the antifungal effect of a fraction from Jacquinia macrocarpa plant extract (JmAF), as well as the morphological and physiological changes that occur during its exposure. The fungus was exposed to JmAF during consecutive periods. A culture sample was taken weekly to determine radial growth, spore germination and size, and fungal β-1,3-glucanase activity. The results showed that, in the beginning, the radial growth decreased by 85.8%, and spore germination was delayed. As the exposure continued, the fungus showed a recovery, to some extent, in its original characteristics. However, the radial growth of the fungus continued to be inhibited (42.9%) throughout the experiment (7 weeks). The β-1,3-glucanase activity also was inhibited by 36.4% during the first week of exposure to JmAF. However, the activity was recovered after 7 weeks of exposure.

本研究旨在确定轮枝镰刀菌在发展机制中的能力，以抵消来自Jacquinia macrocarpa的部分的抗真菌作用植物提取物 (JmAF)，以及在其暴露期间发生的形态和生理变化。真菌在连续期间暴露于 JmAF。每周采集培养样品以确定径向生长、孢子萌发和大小以及真菌 β-1,3-葡聚糖酶活性。结果表明，开始时，径向生长减少了85.8%，孢子萌发延迟。随着暴露的继续，真菌在一定程度上恢复了其原始特征。然而，在整个实验过程中（7 周），真菌的径向生长继续受到抑制（42.9%）。在接触 JmAF 的第一周，β-1,3-葡聚糖酶活性也被抑制了 36.4%。然而，该活性在暴露 7 周后恢复。
