“…The leaves gained the most chlorophyll a, chlorophyll b, and carotenoids with 100 ppm AgNPs [ 69 ]. All concentrations of applied colloidal AgNPs accelerated flowering, increased bulb diameter, and increased the fresh weight of the aboveground portion of the lily plants and bulbs [ 70 ]. The quality and quantity of cut flowers and bulbs produced by lily plants increased with the use of AgNPs solutions at various concentrations.…”

The application of compost and metallic nanoparticles has a significant impact on the productivity and chemical composition of horticulture plants. In two subsequent growing seasons, 2020 and 2021, the productivity of Asclepias curassavica L. plants treated with various concentrations of silver nanoparticles (AgNPs) and compost was assessed. In the pot experiments, the soil was amended with 25% or 50% compost, and the plants were sprayed with 10, 20, and 30 mg/L of AgNPs. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction analysis (XRD), and dynamic light scattering (DLS) were used to characterize AgNPs. The TEM measurements of AgNPs showed that the particles had spherical forms and ranged in size from roughly 5 to 16 nm. Leaf methanol extracts (LMEs) were prepared from the treated plants and assayed against the growth of two soft rot bacteria, Dickeya solani and Pectobacterium atrosepticum. The maximum plant height, diameter, number of branches/plant, total fresh weight (g), total dry weight (g), and leaf area (cm2) was recorded when levels of 25% compost + AgNPs 20 mg/L, 25% compost, or 50% + AgNPs 20 mg/L, 25% compost + AgNPs 30 mg/L or 50% compost + AgNPs 20 mg/L, 50% compost + AgNPs 20 mg/L, 50% compost + AgNPs 30 or 20 mg/L, and 25% compost + AgNPs 30 mg/L, respectively, were applied. The plants treated with 25% or 50% compost + 30 mg/L AgNPs showed a high chlorophyll content, while the plants treated with 50% compost + AgNPs 30 mg/L or 20 mg/L showed the highest extract percentages. The highest inhibition zones (IZs), 2.43 and 2.2 cm, against the growth of D. solani were observed in the LMEs (4000 mg/L) extracted from the plants treated with compost (v/v) + AgNPs (mg/L) at the levels of 50% + 30 and 25% + 30, respectively. The highest IZs, 2.76 and 2.73 cm, against the growth of P. atrosepticum were observed in the LMEs (4000 mg/L) extracted from the plants treated at the levels of 50% + 30 and 25% + 30, respectively. Several phenolic compounds such as syringic acid, p-coumaric acid, chlorogenic acid, cinnamic acid, ellagic acid, caffeic acid, benzoic acid, gallic acid, ferulic acid, salicylic acid, pyrogallol, and catechol, as well as flavonoid compounds such as 7-hydroxyflavone, naringin, rutin, apigenin, quercetin, kaempferol, luteolin, hesperidin, catechin, and chrysoeriol, were identified in the LMEs as analyzed by HPLC with different concentrations according to the treatment of compost + AgNPs used for the plants. In conclusion, the specific criteria that were utilized to measure the growth of A. curassavica revealed the novelty of compost and AgNPs combination treatments, particularly at a concentration of 50% compost + AgNPs 30 mg/L or 20 mg/L, which is better for the growth and phytochemical production of A. curassavica in the field.

“…The search continues for ornamental plants that retain their aesthetic appearance despite stressful conditions (Sun et al, 2022). The negative effects of salt stress on ornamental plants can be attempted to some extent by using seed priming, application of organic and mineral amendments, inoculation with mycorrhizae, application of compatible solutes phytohormones, antioxidant molecules, plant growth regulators, mineral salts, nanoparticles, and biostimulants (García-Caparrós and Lao 2018; Byczyńska et al, 2023). However, one of the best method that can prevent salinization is the cultivation of salinity-tolerant species and cultivars (Guo et al, 2022).…”

Ferns are an essential group of forest plants, however their salt tolerance is poorly understood. This study aimed to evaluate the effect of 50 or 100 mM sodium chloride (NaCl) on the growth, biomass, and ionic potassium (K + ), calcium (Ca 2+ ) and sodium (Na + ) concentrations in the fronds of evergreen ferns: Cyrtomium fortunei var. clivicola, Polystichum setiferum, and Polystichum setiferum 'Proliferum'. Visual quality of the plants immediately after the stress application and after the overwintering period was also carried out. Salinity resulted in the relative chlorophyll content reduction with exposure to increasing NaCl for all ferns. In C. fortunei var. clivicola and P. setiferum, salt stress led to a decrease in plant height, frond length, and weight of the above-ground part of plants as well as visual quality. For P. setiferum 'Proliferum' there was not a significant reduction in fresh and dry weight. Moreover, P. setiferum 'Proliferum' grown under salt stress maintained stable K + concentrations in the fronds and high aesthetic appearance both immediately after the stress factor and after several months. In conclusion, P. setiferum 'Proliferum' was relatively salt-tolerant and Cyrtomium fortunei var. clivicola and P. setiferum were sensitive to soil salinity.

“…Silver nanoparticles, as one of the most recognized nanomaterials, have also been used in plant tissue cultures, protection, fertilization, and flower shelf life extension in horticulture, exhibiting a broad spectrum of biological activity and affecting plant growth and quality (Byczyńska et al, 2023). Studies on AgNPs effects on in vitro seed germination, plant propagation, and metabolite production revealed positive and negative aspects, depending on tested concentration or plant species (Tymoszuk, 2021).…”

Nanotechnology creates opportunities to improve the micropropagation of horticultural plants. The aim of this study was to test the effects of zinc oxide submicron particles (ZnO SMPs), and nanoparticles (NPs) such as ZnO NPs, and ZnO+Ag NPs, at the concentrations of 100, 200, or 400 mg·L−1, on the growth parameters of Chrysanthemum × morifolium (Ramat.) Hemsl. ‘UTP Burgundy Gold’ and ‘UTP Pinky Gold’ plantlets propagated by shoot-tip culture on MS medium. Control shoot culture (without SMPs or NPs) and culture with auxin (MS with indole-3-acetic acid IAA) were also evaluated. Treatments with SMPs, NPs, and IAA stimulated the formation of leaves. Most often, plantlets treated with SMPs and NPs, especially with 100 and 200 mg·L-1 ZnO SMPs, 100 mg·L-1 ZnO NPs 1.5% H2O, and 100 mg·L-1 ZnO+1% Ag NPs 1.5% H2O, produced leaves with the highest area, perimeter and horizontal width, compared to the control and the IAA treatment. Generally, shoot fresh and dry weights of plantlets treated with SMPs, NPs or IAA were higher compared to the control. The highest shoot fresh and dry weights were stated for 400 mg·L-1 ZnO+1%Ag NPs 6% H2O and 100 mg·L-1 ZnO SMPs, respectively, whereas the lowest shoot fresh and dry weights were found for 400 mg·L-1 ZnO+1%Ag NPs 1.5% H2O. The highest values of root system fresh and dry weights were reported for IAA. Contrary, application of 400 mg·L-1 ZnO+0.1%Ag NPs 6% H2O, ZnO+1%Ag NPs 1.5% H2O, and ZnO+1%Ag NPs 6% H2O resulted in the lowest fresh and dry weights of root systems. The auxin treatment also resulted in the highest length, area, and volume of the root system, as well as root diameter and number of root tips and forks. Nevertheless, the treatments with ZnO SMPs and ZnO NPs most often increased the root system parameters against ZnO+Ag NPs. The results are of scientific and practical importance for modulating chrysanthemum plantlets’ architecture during micropropagation.
