“…High regression in chlorophyll content, leaf area index, and dry matter production were recorded under control treatment followed by ZnSO 4 at the recommended dose (24 Kg/ha) except first year, dry matter production under ZnONP 20 occupied the second rank in this regression (1381.5 g/m 2 ). It was previously reported that ZnO NPs (200 ppm) were used to increase the chlorophyll contents of non-photoperiod sensitive rice cultivars, and researchers found that these particles did not show a statistically significant difference for the photosynthetic pigment contents [ 36 ]. They also reported that the accumulation of the antioxidant enzyme activities inhibits the damage of the photosynthetic pigments, due to the toxicity of ZnO NPs.…”

Applications of metal oxide nanoparticles in the agriculture sector are being extensively included as the materials are considered superior. In the present work, zinc oxide nanoparticle (ZnO NPs), with a developing fertilizer, is applied in the fortification of rice grain yield and nutrient uptake enhancement. To evaluate the role of ZnO NP, two field experiments were conducted during the 2018 and 2019 seasons. ZnO NPs were small, nearly spherical, and their sizes equal to 31.4 nm, as proved via the dynamic light scattering technique. ZnO NPs were applied as a fertilizer in different concentrations, varying between 20 and 60 mg/L as a foliar spray. The mixture of ZnSO4 and ZnO NP40 ameliorated yield component and nutrients (N, K, and Zn) uptake was enhanced compared to traditional ZnSO4 treatment. Nevertheless, the uptake of the phosphorous element (P) was adversely affected by the treatment of ZnO NPs. Thus, treatment via utilizing ZnO NPs as a foliar with a very small amount (40 ppm) with of basal ZnSO4 led to a good improvement in agronomic and physiological features; eventually, higher yield and nutrient-enriched rice grain were obtained.

“…However, other studies have reported that Zn supply to the soil with ZnSO 4 and ZnO NPs in high concentrations (400–800 mg/kg) exerted harmful effects on the accumulation of chlorophylls and carotenoids in rice ( Oryza sativa ), bean ( Phaseolus vulgaris ), and tomato plants ( Solanum lycopersicon ) [ 12 , 38 ], due to the toxicity generated by the high absorption of Zn ++ ions within the plant [ 15 ]. In this study, concentrations between 100 to 300 mg/kg of ZnSO 4 and ZnO NPs caused an increase in photosynthetic pigments and carotenoids; on the contrary, with 400 mg/kg of ZnSO 4 , the accumulation of CLHt and carotenoids decreased ( Figure 3 ), which indicates that the higher concentration of Zn ++ in the shoots from that source ( Figure 2 B) could generate toxic effects that affect chlorophyll biosynthesis and damage the photosynthetic system [ 10 ].…”

The objective of this study was to determine the oxidative stress and the physiological and antioxidant responses of coriander plants (Coriandrum sativum) grown for 58 days in soil with zinc oxide nanoparticles (ZnO NPs) and zinc sulfate (ZnSO4) at concentrations of 0, 100, 200, 300, and 400 mg of Zn/kg of soil. The results revealed that all Zn compounds increased the total chlorophyll content (CHLt) by at least 45%, compared to the control group; however, with 400 mg/kg of ZnSO4, chlorophyll accumulation decreased by 34.6%. Zn determination by induction-plasma-coupled atomic emission spectrometry (ICP–AES) showed that Zn absorption in roots and shoots occurred in plants exposed to ZnSO4 at all concentrations, which resulted in high levels of hydrogen peroxide (H2O2) and malondialdehyde (MDA). Only at 400 mg/kg of ZnSO4, a 78.6% decrease in the MDA levels was observed. According to the results, the ZnSO4 treatments were more effective than the ZnO NPs to increase the antioxidant activity of catalase (CAT), ascorbate peroxidase (APX), and peroxidases (POD). The results corroborate that phytotoxicity was higher in plants subjected to ZnSO4 compared to treatments with ZnO NPs, which suggests that the toxicity was due to Zn accumulation in the tissues by absorbing dissolved Zn++ ions.

“…These smaller particles have more mobility, more bioavailability, and more uptake by organisms than bulk particles size . The most studied ZnO nanoparticles size is <50 nm and it was chosen 30 nm ZnO nanoparticles in this study. If ZnO nanoparticles size is smaller than the plant cell pores, nanoparticles can be absorbed and internalize into the plant cells.…”

Effects of ZnO Nanoparticles and Ethylenediamine‐N,N′‐Disuccinic Acid on Seed Germination of Four Different Plants

2019

The release of nanoparticles and biodegradable chelating agents into the environment may cause toxicological and ecotoxicological effects. The aim of this study is to determine the ecotoxic effects of zinc oxide (ZnO) nanoparticles and ethylenediamine disuccinic acid (EDDS) on most cultured four plants. The durum wheat, bread wheat, barley, and rye are exposed to 5 mL 10 mg L−1 ZnO nanoparticles and 10 mg L−1 EDDS in the seed germination stage. Results show that these different plant species have different responses to ZnO nanoparticles and EDDS. The germination percentage of bread wheat and rye decreases in the application of ZnO nanoparticles while the germination of durum wheat and barley increases as much as in radicle elongation and seedling vigor. While ZnO treatment causes a decrease in bread wheat and rye germinated rat in the range of 33–14.3%, respectively, there is no change in germination rate of these plants at EDDS treatment. In addition, EDDS treatment positively affects barley germination rate. In conclusion, it is clear that ZnO nanoparticles have more toxic effects on bread wheat and rye than EDDS, while barley is positively affected by ZnO nanoparticles and EDDS.
