Abstract

Endophytic fungus Penicillium crustosum EP-1 was used to create spherical shape magnesium oxide nanoparticles (MgO-NPs). The MgO-NPs possess a crystalline structure with sizes of 8–35 nm. The weight percentages of Mg and O were 42.44% and 30.13%, respectively, as shown in energy-dispersive X-ray analysis. In addition, analysis involving dynamic light scattering indicated the uniformity of MgO-NPs within the colloidal solution. These NPs displayed a polydispersity index of 0.341 and held a surface charge of −29.7 mV. A field experimental was carried out to assess the outcome of foliar spraying of MgO-NPs at 5, 10, and 20 ppm on the growth, yield, and metabolic activities of Nigella sativa L. Our results indicated that MgO-NPs significantly enhanced various growth parameters, including chlorophyll content (both a and b), total carotenoids, carbohydrate and protein levels in both shoots and seeds, as well as free proline concentration, compared to the control plants at both 55 and 75 days after planting. In addition, all yield traits were markedly increased. Moreover, high-performance liquid chromatography is employed for the identification of phenolic compounds within the seeds. Data indicated that sex phenolic acids, two phenols, and five flavonoids were present with high concentrations due to MgO-NPs treatment as opposed to untreated plants.

利用内生真菌菌株绿色合成氧化镁纳米颗粒以改善黑木耳的生长、代谢活性、产量性状和酚类化合物含量

利用内生真菌甲壳青霉 EP-1 制造球形氧化镁纳米粒子（MgO-NPs）。MgO-NPs 具有晶体结构，尺寸为 8-35 nm。能量色散 X 射线分析显示，Mg 和 O 的重量百分比分别为 42.44% 和 30.13%。此外，动态光散射分析表明了 MgO-NPs 在胶体溶液中的均匀性。这些 NPs 的多分散指数为 0.341，表面电荷为 -29.7 mV。我们进行了一项田间试验，以评估叶面喷洒 5、10 和 20 ppm 的 MgO-NPs 对黑麦草（Nigella sativa L）的生长、产量和代谢活动的影响。结果表明，与对照植物相比，MgO-NPs 能显著提高种植后 55 天和 75 天的各种生长参数，包括叶绿素含量（a 和 b）、类胡萝卜素总量、芽和种子中的碳水化合物和蛋白质含量以及游离脯氨酸浓度。此外，所有产量性状都明显增加。此外，还采用了高效液相色谱法来鉴定种子中的酚类化合物。数据表明，与未处理的植物相比，MgO-NPs 处理后的种子中含有高浓度的性酚酸、两种酚类和五种黄酮类化合物。
