“…In the mean time, there was gradual increase with increasing nano-micronutrients concentrations in the above mentioned parameters. These results coincided with those reported by Mohsenzadeh and Moosavian (2017) on rosemary, Rezaei-Chiyaneh et al (2018) on black cumin and Sabet and Mortazaeinezhad (2018) on cumin plants.…”

The present study was carried out to evaluate the effect of different phosphorus fertilization rates at [0.0, 30 and 45 kg/feddan as P 2 O 5 , nano micronutrients concentrations (0.0, 250, 500 and 100 mg/l) as well as their combinations on growth and production of fennel (Foeniculum vulgare, L.). A field experiment was carried out at Experimental Farm (Ghazala Farm), Fac. Agric., Zagazig Univ., Egypt, during the two winter consecutive seasons of 2017/2018 and 2018/2019. Phosphorus fertilization as main plots and nano-micronutrients called "Magro NanoMix" which contained (Fe 6%, Zn 6%, B 2%, Mn 5%, Cu 1% and Mo 0.1%) as subplots were considered. The obtained results showed the importance of the nano-micronutrients on improving fennel growth, fruits and volatile oil yield compared to control. Fennel plants treated with phosphorus fertilizer or/and nano micronutrients instigated critical increments in vegetative growth (plant height and branch number/plant as well as dry weight of herb/plant), yield (number of inflorescence /plant, fruit yield/plant and /feddan), volatile oil production (volatile oil percentage and yield/plant and /feddan) and some chemical constituents (total phosphorus, total carbohydrates percentage and total chlorophyll content), as contrasted and untreated plants. In general, 45 kg P 2 O 5 /feddan + 500 or 1000 mg/l of nano-micronutrients as foliar spray had significant effects in above mentioned parameters of fennel plant compared to the other combinations under Sharkia Governorate conditions.

“…Zn is a vital component for the development of protochlorophyllide and improves the chloroplast functioning and helps in repairs of photosystem II [29]. An enhancement in carotenoid contents may be related to the response of plants to oxidative damage [30]. The antioxidant enzymes CAT, POD and SOD, scavenge ROS-in plants and supply protection and defense to plant cells from the oxidative stress of reactive free radicals [31].…”

The study investigated the green and chemical approaches for the preparation of Zn nanoparticles and their effect on the growth of okra plants under saline conditions. The leaf extract of Sorghum bicolor L. was used for the green synthesis of zinc nanoparticles (Zn-GNPs). Zinc nanoparticles (Zn-NPs) were also produced by the co-precipitation method (Zn-CNPs). The synthesized NPs were characterized by UV-visible spectroscopy, X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) and were applied foliarly in the range of 0.1%, 0.2%, 0.3% on okra plants. A marked increase in the shoot and root fresh and dry weight (g) and chlorophyll contents were observed under normal and saline conditions. An increase in antioxidant activity was observed under saline conditions. However, the foliar application of 0.3% Zn-GNPs was helpful in the regulation of the antioxidant defense system under a saline environment. Based on the results, it can be concluded that the use of Zn-GNPs is the most promising eco-friendly approach in mitigating salinity stress.

“…It was hypothesized that ZnO-NPs involved in the rise of plant chlorophyll-and exceedingly efficient in the synthesis of photosynthetic pigments that increased photosynthesis rate [35]. It might be because nanoparticles are powerful amplifiers of photosynthetic effectiveness that in parallel cause light absorption by chlorophyll, as it causes convey of energy to nanoparticles from chlorophyll [36]. As observed in this work, the higher contents of carotenoids and anthocyanins formed by AgNPs exposure might be because of higher oxidative stress caused by AgNPs.…”

They were shifting in land use increases salinity stress, significant abiotic stress affecting plant growth, limiting crop productivity. This work aimed to improve Linum usitatissimum L. (linseed) growth under salinity using Comamonas testosteroni and silver nanoparticles (AgNPs). AgNPs were fabricated exploiting Rosmarinus officinalis and monitored by U.V./Vis spectrophotometry scanning electron microscopy (SEM) and Fourier transforms infrared spectroscopy (FTIR). Photosynthetic pigments, enzymatic and nonenzymatic antioxidants of linseed were investigated under salt stress in treated and untreated plants with C. testosteroni alongside AgNPs. Our findings recorded the formation of AgNPs at 457 nm, which were globular and with a diameter of 75 nm. Notably, chlorophyll-a, b, and total chlorophyll reduction while enhanced carotenoids and anthocyanin contents were attained under salinity stress. Total dissoluble sugars, proline, and dissoluble proteins, H2O2, malondialdehyde, enzymatic and nonenzymatic antioxidants were significantly elevated in NaCl well. Combined AgNPs and C. testosteroni elevated photosynthetic pigments. Also, they led to the mounting of soluble sugars, proline, and soluble proteins. H2O2 and malondialdehyde decreased while enzymatic and nonenzymatic antioxidants increased in response to AgNPs, C. testosteroni, and their combination. Thus, AgNPs and C. testosteroni might bio-fertilizers to improve linseed crop productivity under salinity stress.
