“…sinensis leaves with 10 ppm CNPs, POX, SOD and PPO activity levels of these plants were 4, 1.7 and 3.5 times than untreated control plants. In the same way, Abdel-Aziz [ 79 ] reported that using CNPs significantly increased the activity of antioxidant enzymes, including peroxidase and PPO in Vicia faba . Similar results showed that chitosan increases the activity of antioxidant enzymes, including SOD, POX and GPO, in other plants [ 21 , 49 , 69 , 80 ].…”

Background The use of organic nanoparticles to improve drought resistance and water demand characteristics in plants seems to be a promising eco-friendly strategy for water resource management in arid and semi-arid areas. This study aimed to investigate the effect of chitosan nanoparticles (CNPs) (0, 30, 60 and 90 ppm) on some physiological, biochemical, and anatomical responses of Salvia abrotanoides under multiple irrigation regimes (30% (severe), 50% (medium) and 100% (control) field capacity). Results The results showed that drought stress decreases almost all biochemical parameters. However, foliar application of CNPs mitigated the effects caused by drought stress. This elicitor decreased electrolyte conductivity (35%), but improved relative water content (12.65%), total chlorophyll (63%), carotenoids (68%), phenol (23.1%), flavonoid (36.4%), soluble sugar (58%), proline (49%), protein (45.2%) in S. abrotanoides plants compared to the control (CNPs = 0). Furthermore, the activity of antioxidant enzymes superoxide dismutase (86%), polyphenol oxidase (72.8%), and guaiacol peroxidase (75.7%) were enhanced after CNPs treatment to reduce the effects of water deficit. Also, the CNPs led to an increase in stomatal density (5.2 and 6.6%) while decreasing stomatal aperture size (50 and 25%) and semi-closed stomata (26 and 53%) in leaves. Conclusion The findings show that CNPs not only can considerably reduce water requirement of S. abrotanoides but also are able to enhance the drought tolerance ability of this plant particularly in drought-prone areas.

“…The seed coat is the primary line of defense against environmental stress and pathogen invasion, and it plays an important role in determining seed vitality and germination [ 24 , 25 ]. Abdel-Aziz also found that higher concentrations of chitosan nanoparticles adversely affected germination and seedling growth [ 26 ]. This effect could be due to stimulating capacity of chitosan nanoparticles metabolic activity, which enhances the intrinsic potential for seed development through the absorption of chitosan nanoparticles through imbibition, coating, or seed priming [ 27 – 29 ].…”

Background Nanotechnology has demonstrated its vital significance in all aspects of daily life. Our research was conducted to estimate the potential of primed seed with chitosan nanoparticles in seed growth and yield by inducing plant secondary metabolism of Pancratium maritimum L. one of the important medicinal plants. Petri dish and pot experiments were carried out. Seeds of Pancratium maritimum L. were soaked in Nano solution (0.1, 0.5, 1 mg/ ml) for 4, 8, 12 h. Germination parameters (germination percentage, germination velocity, speed of germination, germination energy, germination index, mean germination time, seedling shoot and root length, shoot root ratio, seedling vigor index, plant biomass and water content), alkaloids and antioxidant activity of Pancratium maritimum L. were recorded and compared between coated and uncoated seeds. Results Our results exhibited that chitosan nanopriming had a positive effect on some growth parameters, while it fluctuated on others. However, the data showed that most germination parameters were significantly affected in coated seeds compared to uncoated seeds. GC-MS analysis of Pancratium maritimum L. with different nanopriming treatments showed that the quantity of alkaloids decreased, but the amount of pancratistatin, lycorine and antioxidant content increased compared with the control. Conclusions Applying chitosan nanoparticles in priming seeds might be a simple and effective way to improve the quantity of secondary metabolites of Pancratium maritimum L. valuable medicinal plant.

“…CAT plays an indispensable role in detoxification activity under stress (Yang et al, 2017) and can be changed by MO NPs (Du et al, 2017). A number of studies also showed that lower concentrations of Zn NPs changed CAT activity and enhanced the plant defence system under stress (Abdel‐Aziz, 2019; Du et al, 2017; Hernandez‐Viezcas et al, 2011; Raigond et al, 2017; Zhao et al, 2015). Abdel‐Aziz (2019) also mentioned that lower concentrations of Zn NPs changed CAT activity and indicated that relatively low levels of NPs enhanced the plant defence system by increasing the antioxidant EA in lupine plants under stress.…”

There is no accurate information on the effect of metal oxide nanoparticles (MO NPs) on plant enzymatic activities (EAs) under drought stress (DS). The aim of this work was to study the effect of MO NPs on the EAs of Agropyron cristatum (L.) Gaertn and Sanguisorba officinalis L. under DS. Foliar spray of silver oxide (AgO), iron oxide (FeO), zinc oxide (ZnO) and cadmium oxide (CdO) at levels of 30, 60, 90 and 120 mg L−1 were used on plant aerial parts under DS levels of 25–100% field capacity (FC). Glutathione reductase (GR), catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) were measured after 2 weeks of the experiment. The EAs changes varied depending on the plant species, levels of DS, types and levels of NPs. Application of 30–60 mg L−1 MO NPs under 25–50% FC significantly reduced EAs, especially in S. officinalis (P < 0.01). Higher concentrations of MO NPs significantly increased EAs. Decreases in CAT (20.90%, 18.80%), POD (21.30%, 17.67%) and SOD (23.14%, 16.88%) were observed using 60 mg L−1 ZnO NPs under 25–50% FC in S. officinalis and A. cristatum, respectively. High concentrations of CdO NPs (90–120 mg L−1) increased EAs (max. = 24.0%) in both species under 25% FC.
