Although the presence of silicon (Si) as a phyto-beneficial element is not essential in the nutrition of ornamental plants, its application may have many advantageous effects. Therefore, the present research was conducted to investigate the effects of Si and synthesized silicon nanoparticles (SiNPs) on the morphological and biochemical properties, leaf nutrient content, and vase life of tuberose (Polianthes tuberosa L.). Si and SiNPs were applied at 200 mg L⁻¹ and 400 mg L⁻¹ via root or foliar application under greenhouse conditions. The results showed that the application of two silicon sources by foliar or root, with increasing leaf phosphorus and Si contents, substantially enhanced total soluble carbohydrate and protein. Morphological parameters, including leaf fresh weight, root volume, root and bulblet dry weight, flowering stem length, flowering-stem dry weight, and floret number were improved. The flower vase life in treated plants was longer than non-treated ones and ranged from 32% for 200 mg L⁻¹ SiNPs by root application to 60% for 200 mg L⁻¹ Si and 400 mg L⁻¹ SiNPs by foliar. In most of the evaluated parameters, SiNPs had a relative superiority to Si, particularly when sprayed. A heat-map analysis of traits also revealed that the concentration of conventional Si has great prominence than its application method. In contrast, the method of applying SiNPs is more critical than its concentration. It is concluded that foliar application of SiNPs at 400 mg L⁻¹ can be recommend for improving the growth and flowering of tuberose plants, although the root application of Si at 200 mg L⁻¹ also had relatively acceptable results.

尽管作为植物有益元素的硅（Si）的存在对于观赏植物的营养并不是必需的，但其应用可能会产生许多有利的影响。因此，进行本研究以研究Si和合成的硅纳米颗粒（SiNPs）对晚香玉（Polianthes tuberosa L.）的形态和生化特性，叶片养分含量和花瓶寿命的影响。分别以200 mg L ^-1和400 mg L ^-1施用Si和SiNPs在温室条件下通过根或叶面施用。结果表明，通过叶面或根部施用两种硅源，随着叶磷和硅含量的增加，大大提高了总可溶性碳水化合物和蛋白质含量。形态参数，包括叶鲜重，根体积，根和鳞茎干重，开花茎长，开花茎干重和小花数均得到改善。处理过的植物中的花瓶寿命比未处理过的植物更长，范围从根部施用200 mg L ^-1 SiNPs的32％到200 mg L ^-1 Si和400 mg L ^-1的60％。SiNP由叶面形成。在大多数评估参数中，SiNP比Si具有相对优势，尤其是在喷涂时。对特征进行热图分析还表明，常规硅的浓度比其应用方法要突出。相反，应用SiNPs的方法比其浓度更为关键。可以得出结论，尽管200 mg L ^-1的Si根部施用也具有相对可接受的结果，但建议以400 mg L ^-1的叶面施用SiNPs改善晚香玉植物的生长和开花。
