“…1b,d and 2b). This is in agreement with the results obtained in Medicago arborea, as no differences were found between the control and the different Ce levels added (100, 200, and 400 mg L −1 ) regarding root length, leaf number, both fresh and dry weight of the stem, and chlorophyll concentrations (SPAD units) and the efficacy of photosystem II (Gomez-Garay et al 2014). Similarly, 10 μM Ce had no effect on plant height, fresh weight, and chlorophyll and carotenoid contents in rice seedlings (Wu et al 2014).…”

The aim was to evaluate the application of three non-essential beneficial elements such as vanadium (V), selenium (Se), and cerium (Ce) during tomato and pepper seedling production in order to improve their quality. Low concentrations of these elements may promote plant growth and improve tolerance towards stress, and they could also increase the nutritional value of vegetable foods. The seeds from tomato and pepper were sown in germination trays containing commercial substrates, and the experiment was established in a greenhouse. Twenty days after seeding, one weekly irrigation was performed with 50% Hoagland nutrient solution (control) plus either 3, 5, or 10 μM NH 4 VO 3 ; 5, 10, or 20 μM Na 2 SeO 3 ; and 25, 50, or 100 μM CeCl 3 . After four weekly applications, it was observed that all three V doses (3, 5, and 10 μM) and the lowest Se concentration (5 μM) promoted the growth of both root and shoots, and they increased the dry biomass for both tomato and pepper seedlings. Only the addition of 50 μM Ce promoted tomato seedling growth. Both V and Se increased the content of phenolic compounds on pepper seedlings. These elements may be used for seedling production at plant nursery level in order to ensure their uniformity and quality. It is an innovative tool to ensure maximum yield of crops.

“…As per a review of metal nanoparticle interactions with plants, there are many examples of nanoparticle-specific effects that are distinctive from constituent metals (Ma et al, 2015a). The use of non-nanoscale (negative) experimental controls, for example bulk ZnO (Mukherjee et al, 2014) or CeO 2 (Gomez-Garay et al, 2014), would allow for determining if the nano-scale imparts special toxicities to particulate metal oxides amended to planted soils.…”

With increasing use, manufactured nanomaterials (MNMs) may enter soils and impact agriculture. Herein, soybean (Glycine max) was grown in soil amended with either nano-CeO (0.1, 0.5, or 1.0gkg soil) or nano-ZnO (0.05, 0.1, or 0.5gkg soil). Leaf chlorosis, necrosis, and photosystem II (PSII) quantum efficiency were monitored during plant growth. Seed protein and protein carbonyl, plus leaf chlorophyll, reactive oxygen species (ROS), lipid peroxidation, and genotoxicity were measured for plants at harvest. Neither PSII quantum efficiency, seed protein, nor protein carbonyl indicated negative MNM effects. However, increased ROS, lipid peroxidation, and visible damage, along with decreased total chlorophyll concentrations, were observed for soybean leaves in the nano-CeO treatments. These effects correlated to aboveground leaf, pod, and stem production, and to root nodule N fixation potential. Soybeans grown in soil amended with nano-ZnO maintained growth, yield, and N fixation potential similarly to the controls, without increased leaf ROS or lipid peroxidation. Leaf damage was observed for the nano-ZnO treatments, and genotoxicity appeared for the highest nano-ZnO treatment, but only for one plant. Total chlorophyll concentrations decreased with increasing leaf Zn concentration, which was attributable to zinc complexes-not nano-ZnO-in the leaves. Overall, nano-ZnO and nano-CeO amended to soils differentially triggered aboveground soybean leaf stress and damage. However, the consequences of leaf stress and damage to N fixation, plant growth, and yield were only observed for nano-CeO.

“…Cerium oxide ( n CeO 2 ) and titanium oxide ( n TiO 2 ) nanoparticles are both included in the list of engineered nanomaterials with priority for immediate testing [ 17 ]. A number of papers report data collected in the course of short experiments exposing plants to n CeO 2 or n TiO 2 conducted on seedlings in petri-dishes [ 18 , 19 , 20 , 21 ], in hydroponic solutions or perlite-containing pots [ 11 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ], and in nutrient medium in agar [ 29 , 30 ]. Other scientists worked on experiments in pots with plants being sprayed with n TiO 2 on leaves [ 31 , 32 , 33 , 34 , 35 ].…”

The implications of metal nanoparticles (MeNPs) are still unknown for many food crops. The purpose of this study was to evaluate the effects of cerium oxide (nCeO2) and titanium oxide (nTiO2) nanoparticles in soil at 0, 500 and 1000 mg·kg−1 on the nutritional parameters of barley (Hordeum vulgare L.) kernels. Mineral nutrients, amylose, β-glucans, amino acid and crude protein (CP) concentrations were measured in kernels. Whole flour samples were analyzed by ICP-AES/MS, HPLC and Elemental CHNS Analyzer. Results showed that Ce and Ti accumulation under MeNPs treatments did not differ from the control treatment. However, nCeO2 and nTiO2 had an impact on composition and nutritional quality of barley kernels in contrasting ways. Both MeNPs left β-glucans unaffected but reduced amylose content by approximately 21%. Most amino acids and CP increased. Among amino acids, lysine followed by proline saw the largest increase (51% and 37%, respectively). Potassium and S were both negatively impacted by MeNPs, while B was only affected by 500 mg nCeO2·kg−1. On the contrary Zn and Mn concentrations were improved by 500 mg nTiO2·kg−1, and Ca by both nTiO2 treatments. Generally, our findings demonstrated that kernels are negatively affected by nCeO2 while nTiO2 can potentially have beneficial effects. However, both MeNPs have the potential to negatively impact malt and feed production.
