“…Exposure to high levels of chromium reduces essential oil content by hindering nutrient absorption, lowering photosynthesis potential, and by reducing the chlorophyll content, leaf area, and energy required for essential oil biosynthesis [85,89,90]. It has been demonstrated that exposing plants to heavy metals leads to severe oxidative stress, primarily due to the generation of high levels of reactive oxygen species (ROS), which can damage essential macromolecules in plant cells [31,91,92]. On the other hand, CS-NPs may boost photosynthesis, leading to an improvement in EO and EOY [93,94].…”

An excessive amount of chromium in soil has detrimental effects on plant processes, and impairs food security, and public health. The application of nanoparticles may be a suitable solution and an innovative strategy by which to reduce plant abiotic stresses and pollution in the agricultural ecosystems. This research focuses on the effects of chitosan nanoparticles (CS-NPs) on thyme (Thymus vulgaris L.) plants grown in Cr-contaminated soil. The effects of CS-NPs as a soil amendment at four concentrations were investigated on plant nutrient uptake, photosynthesis parameters, antioxidant system, and essential oil (EO) content under soil Cr stress. The results show that chromium stress reduced fresh and dry weight of shoots, the uptake of macro-, and micro-elements, chlorophyll and carotenoids. The application of CS-NPs improved the antioxidant enzyme activity, reduced malondialdehyde, and increased the content of nutrients, EOs, photosynthetic pigments, and chlorophyll fluorescence parameters. The intermediate dose of chitosan nanoparticles (0.1% w/v) best valorized the content and yield of thyme EOs under chromium stress. These results are indicative that the application of CS-NPs can represent a supportive approach for plant production in soils contaminated with heavy metals.

Metal nanoparticles (NPs) have been highlighted to improve plant growth and development in the recent years. Although positive effects of some NPs have been reported on medicinal plants, the knowledge for stimulations application of iron (Fe) and zinc (Zn) NPs is not available. Hence, the present work aimed to discover the effects of Fe NPs at 10, 20, and 30 mg L − 1 and Zn NPs at 60 and 120 mg L − 1 on growth, water content, photosynthesis pigments, phenolic content, essential oil (EO) quality, and rosmarinic acid production of lemon balm (Melissa o cinalis L.). The results showed that Fe NPs at 20 and 30 mg L − 1 and Zn NPs at 120 mg L − 1 signi cantly improved biochemical attributes. Compared with control plants, the interaction of Fe NPs at 30 mg − 1 and Zn NPs at 120 mg L − 1 led to noticeable increases in shoot weigh (72%), root weight (92%), chlorophyll (Chl) a (74%), Chl b (47%), rosmarinic acid (66%), proline (1.8fold), glycine betaine (GB, 3.3-fold), protein (3.8-fold), relative water content (8%), EO yield (3.1-fold), total phenolic content (63%), and total avonoid content (57%). The agglomerative hierarchical clustering represented three different clusters for Zn NPs levels and three clusters for Fe NPs concentrations so that NPs at 10 and 20 mg L − 1 were placed in one cluster. Heat map analysis revealed that protein, GB, EO yield, shoot weight, root weight, and proline possessed the maximum changes upon Fe NPs. Totally, the present study recommended the stimulations application of Fe NPs at 20-30 mg L − 1 and Zn NPs at 120 mg L − 1 to reach the optimum growth and secondary metabolites of lemon balm.
