Date palm ( L.) inflorescence rot caused by poses a serious threat to date palm in Morocco. The present study aims to determine the antifungal activity of five plant extracts against , including , , , , and and link this effect to their content in phenolics and flavonoids, as well as their antioxidant properties. Plant extracts exhibited significant discrepancies regarding their antifungal activity ( < 0.05). The extracts of and had the strongest and dose-dependent manner inhibitory effect against mycelial growth and spore germination. and caused the greatest sporulation reductions of about 88.05% and 36.11%, respectively. In addition, there were significant differences among the examined plant extracts with respect to their total polyphenols (14.52-76.68 mg GAE/g DW), flavonoids (8.75-57.78 g RE/100 g DW), and antioxidant properties as measured by TEAC (74.77-391.23 mmol TE/g DW) and FRAP assays (87.18-474.04 mmol TE/g DW). Strong correlations were found between phenolic compounds and antioxidant activity suggesting that polyphenols play a key role in the observed antioxidant and antifungal activities.
海枣（Phoenix dactylifera L.）花序腐烂病由[病原体名称未给出]引起，对摩洛哥的海枣构成严重威胁。本研究旨在测定五种植物提取物对[病原体名称未给出]的抗真菌活性，这五种植物提取物包括[植物名称1]、[植物名称2]、[植物名称3]、[植物名称4]和[植物名称5]，并将这种作用与其酚类和黄酮类化合物的含量以及抗氧化特性联系起来。植物提取物在抗真菌活性方面表现出显著差异（P < 0.05）。[植物名称1]和[植物名称2]的提取物对菌丝生长和孢子萌发具有最强的剂量依赖性抑制作用。[植物名称3]和[植物名称4]分别导致最大的孢子形成减少，约为88.05%和36.11%。此外，在所检测的植物提取物中，其总多酚（14.52 - 76.68毫克没食子酸当量/克干重）、黄酮类化合物（8.75 - 57.78克芦丁当量/100克干重）以及通过TEAC（74.77 - 391.23毫摩尔TE/克干重）和FRAP测定法（87.18 - 474.04毫摩尔TE/克干重）测得的抗氧化特性方面存在显著差异。在酚类化合物与抗氧化活性之间发现了强相关性，这表明多酚在观察到的抗氧化和抗真菌活性中起关键作用。
