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^-1) was carried out on cucumber cultivars (Emilie, Mirsoltan, Mitio, and Viola). The application of Si NPs at 300 mg L^-1 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^-1 and Mito at 300 mg L^-1. Plants experiencing Si NPs at 300 mg L^-1 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^-1. 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^-1, 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^-1 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^-1 enhanced fruit yield, and Mito showed the highest yield when compared to other cultivars.

硅纳米颗粒（Si NP）通过提高产量在提高植物产量方面发挥着重要作用。本研究旨在探讨硅纳米粒子对不同黄瓜品种的植物产量、生化特性和矿物质的影响。在黄瓜品种（Emilie、Mirsoltan、Mitio 和 Viola）上进行了叶面喷施 Si NP（100、200 和 300 mg·L ^-1 ）的温室试验。施用300 mg·L ^-1 Si NPs 的果实产量最高，与对照相比，果实产量增加了 17%。 100 mg·L ^-1 的 Emilie 和 Si NP 以及 300 mg·L ^-1 的 Mito 之间的果实硬度相差 31%。经历 300 mg L L ^-1 Si NP 的植物具有最大的叶绿素 (Chl) a+b。与其他品种相比，Mito 的果实产量和叶绿素含量更高。与 300 mg·L 的对照相比，Si NPs 使 TSS 增加了 11%，同时使 TA 降低了 24% ^-1 。叶面喷施 Si NPs 降低了 TSS/TA 值。硅纳米粒子添加量为200 mg·L ^-1 时，水户品种的钾含量达到最大，比对照增加了22%，表明硅纳米粒子显着提高了钾含量。 200 mg·L ^-1 的 Si NPs 使 Mito 品种的叶片 N 和 P 分别显着增加了 16% 和 50%。通过使用凝聚层次聚类 (AHC)，Emilie 和 Mito 位于两个独立的集群中，而 Viola 和 Mirsoltan 则分在一个集群中。总之，200-300 mg·L ^-1 的 Si NPs 提高了果实产量，与其他品种相比，Mito 的产量最高。
