“…The results revealed the significant increases in all photosynthetic pigment contents (chlorophyll a, chlorophyll b, carotenoids, and total pigments) in response to treatment with different concentrations of AgNPs. This is in line with the results obtained by Farghaly and Nafady (2015) and Latif et al (2017) who reported that AgNPs significantly promote photosynthesis and it is closely related to the change of nitrogen metabolism. Also, Racuciu and Creange (2007) reported that chlorophyll content of maize plants was increased with low concentration (10-50 μl/l) of AgNP treatment while it was found to be inhibited at higher concentrations of NPs.…”

“…More or less similar data were observed by Salama (2012b) who noticed that low concentrations of AgNPs had a stimulating effect on the growth of the common bean and corn plants. Latif et al (2017) showed that AgNP foliar treatment with different concentrations increased growth parameters of the wheat plant. The induced growth increases caused by different AgNP concentrations especially at 40 mg/l might be due to the role of AgNPs in blocking ethylene signaling in fenugreek plant (Rezvani et al 2012).…”

Background: The use of nanotechnology can ensure food security via improving crop production. Nanoparticles have the ability to enhance growth and yield of different plants such as fenugreek (Trigonella foenum-graecum) (Fabaceae). The present work aims to study the role of silver nanoparticles (AgNPs) on growth, some biochemical aspects, and the yield both quantitatively and qualitatively of fenugreek plant. AgNPs were synthesized by chemical reduction of silver nitrate with trisodium citrate. Results: Foliar application of AgNPs with different concentrations (20, 40, and 60 mg/l) improved the growth parameters of fenugreek plant (e.g., shoot length, number of leaves/plant, and shoot dry weight) and increased some biochemical aspects such as photosynthetic pigment (chlorophyll a, chlorophyll b, and carotenoids) and indole acetic acid (IAA) contents thus enhanced the yield quantity (number of pods/plant, number of seeds/pod, weight of seeds/plant, and seed index) and quality (carbohydrate%, protein%, phenolics, flavonoids, and tannins contents) of the yielded seeds as well as increasing antioxidant activity of the yielded seeds. Conclusion: The most effective treatment was 40 mg/l as it caused the highest increases in the studied parameters.

“…We also saw enhanced accumulation of potassium, accompanied by greater content of nitrogen in plants treated with AgNPs at 50 ppm. Stimulation of chlorophyll synthesis following AgNP foliar application has been demonstrated previously in the leaves of Triticum aestivum [18]. AgNPs are assumed to exert a pleiotropic effect on plants by affecting their physiological and biochemical processes and gene expression profiles.…”

“…They affect plants at many different levels [13,14]. Positive effects of AgNPs include stimulation of germination [15], growth invigoration [16], increased biomass accumulation [17], improved shoot induction and proliferation [7], or enhanced pigment content [18]. Silver nanoparticles may also show phytotoxicity, manifested by limited germination and seedling growth [19], decreased biomass of leaves and shoots [20], delay in flowering time, and inhibition of photosynthesis [21].…”

Stimulatory Effect of Silver Nanoparticles on the Growth and Flowering of Potted Oriental Lilies

Nanoparticles exhibit unique biological activities and may serve as novel plant growth stimulators. This research consisted of a two-year pot experiment designed to find out if silver nanoparticles (AgNPs) might be used in the cultivation of Oriental lilies. In the first year, we evaluated the effects of various concentrations of AgNPs (0, 25, 50, 100, and 150 ppm) and their application methods (pre-planting bulb soaks, foliar sprays, and substrate drenches) on the growth and flowering of Lilium cv. Mona Lisa. In the second year, we evaluated the effects of soaking the bulbs of cv. Little John in the same concentration of AgNP solution on plant morphological features, leaf content of photosynthetic pigments, basic macronutrients, and complex biomolecules with the use of the Fourier-transform infrared spectroscopy (FTIR). Soaking the bulbs in a nanoparticle solution turned out to be the most effective strategy for growth and flowering promotion. AgNPs stimulated plant growth, as manifested by enhanced accumulation of leaf and bulb biomass and accelerated flowering. Moreover, plants treated with silver nanoparticles showed higher leaf greenness index, formed more flowers, and flowered longer. At 100 ppm AgNPs, the leaves accumulated the highest content of chlorophyll a, chlorophyll b, and carotenoids, and were the richest in potassium, calcium, and sulfur. The FTIR spectra did not show any changes in absorbance intensity and chemical composition in the leaves from AgNP-treated bulbs.

“…O. basilicum has been explored for its in vitro potential using several types of cultures, notably hairy root 10 and callus cultures. 11 Recently, studies were performed on in vitro cultures to determine the potential of O. basilicum 12,13 for nanoparticle synthesis. Medicinal plants such as O. basilicum contain biologically active compounds, e.g.…”
