Silicon nanoparticles (Si NPs) have an eminent role in improving plant yield through improving yield. The present study was conducted to find the effect of Si NPs on plant yield, biochemical attributes, and minerals of different cucumber cultivars. The greenhouse experiment with foliar application of Si NPs (100, 200, and 300 mg L) was carried out on cucumber cultivars (Emilie, Mirsoltan, Mitio, and Viola). The application of Si NPs at 300 mg L led to the highest fruit yield, with a 17% increase in fruit production compared to the control. Fruit firmness differed by 31% between Emilie and Si NPs at 100 mg L and Mito at 300 mg L. Plants experiencing Si NPs at 300 mg L had the greatest chlorophyll (Chl) a+b. Compared to the other cultivars, Mito had a greater fruit yield and Chl content. The Si NPs increased TSS by 11% while lowering TA by 24% when compared to the control at 300 mg L. Foliar application of Si NPs reduced the value of TSS/TA. The largest value of K was reached in the Mito cultivar with Si NPs at 200 mg L, with a 22% increase in comparison to the control, indicating that Si NPs considerably boosted the K content. The Si NPs at 200 mg L significantly increased leaf N and P in the Mito cultivar by 16 and 50%, respectively. By using agglomerative hierarchy clustering (AHC), Emilie and Mito were located in two separate clusters, whilst Viola and Mirsoltan were grouped in one cluster. In conclusion, Si NPs at 200-300 mg L enhanced fruit yield, and Mito showed the highest yield when compared to other cultivars.
硅纳米颗粒（Si NPs）通过提高产量在提高植物产量方面发挥着重要作用。本研究旨在研究 Si NPs 对不同黄瓜品种的产量、生化特性和矿物质的影响。在温室中进行了叶面喷施 Si NPs（100、200 和 300 mg/L）的实验，实验品种为 Emilie、Mirsoltan、Mito 和 Viola。与对照相比，喷施 Si NPs 300 mg/L 可使果实产量最高，增产 17%。果实硬度在 Emilie 和 Si NPs 100 mg/L 之间以及 Mito 和 Si NPs 300 mg/L 之间差异为 31%。在 300 mg/L Si NPs 处理下，植物的叶绿素（Chl）a+b含量最高。与其他品种相比，Mito 的果实产量和 Chl 含量更高。与对照相比，喷施 Si NPs 300 mg/L 可使 TSS 增加 11%，而 TA 降低 24%。叶面喷施 Si NPs 降低了 TSS/TA 的比值。在 200 mg/L Si NPs 处理下，Mito 品种的 K 值最大，比对照增加 22%，表明 Si NPs 显著提高了 K 含量。在 200 mg/L Si NPs 处理下，Mito 品种的叶片 N 和 P 分别增加了 16%和 50%。通过使用凝聚层次聚类（AHC），Emilie 和 Mito 被分为两个不同的聚类，而 Viola 和 Mirsoltan 被分为一个聚类。总之，喷施 200-300 mg/L 的 Si NPs 可提高果实产量，与其他品种相比，Mito 的产量最高。
