“…TiO 2 application caused a remarkable increase in essential oil content under control conditions with maximum content being observed at 100 mg L −1 concentration. Results were in accordance to those reported by Ahmad et al 66 , who demonstrated that TiO 2 NP application increased essential oil content in Mentha piperita L. Furthermore, Lafmejani et al 67 reported that Fe NPs foliar application increased essential oil content in M. piperita plants. Such an increase in essential oil content could be potentially explained by the observed increase in growth, photosynthesis, expression of secondary metabolite enzymes and size and distribution of oil glands as special sites for biosynthesizing essential oils following NP application 66 .…”

“…In line with the increase in essential oil content, 100 mg L −1 TiO 2 NP application increased main components of essential oil profile. This could be the result of increased expression of specific biosynthetic enzymes involved in the production of components and availability of substrates, in line with previous findings by Ahmad et al 66 and Lafmejani et al 67 . The actual mechanism by which NP application modulates plant secondary metabolites is not yet fully elucidated.…”

considering titanium dioxide nanoparticles (tio 2 nps) role in plant growth and especially in plant tolerance against abiotic stress, a greenhouse experiment was carried out to evaluate TiO 2 NPs effects (0, 50, 100 and 200 mg L −1) on agronomic traits of Moldavian balm (Dracocephalum moldavica L.) plants grown under different salinity levels (0, 50 and 100 mM NaCl). Results demonstrated that all agronomic traits were negatively affected under all salinity levels but application of 100 mg L −1 tio 2 nps mitigated these negative effects. TiO 2 NPs application on Moldavian balm grown under salt stress conditions improved all agronomic traits and increased antioxidant enzyme activity compared with plants grown under salinity without tio 2 NP treatment. The application of TiO 2 NPs significantly lowered H 2 o 2 concentration. In addition, highest essential oil content (1.19%) was obtained in 100 mg L −1 tio 2 nptreated plants under control conditions. Comprehensive GC/MS analysis of essential oils showed that geranial, z-citral, geranyl acetate and geraniol were the dominant essential oil components. The highest amounts for geranial, geraniol and z-citral were obtained in 100 mg L −1 tio 2 np-treated plants under control conditions. In conclusion, application of 100 mg L −1 tio 2 NPs could significantly ameliorate the salinity effects in Moldavian balm. Moldavian balm (Dracocephalum moldavica L.), a perennial herb of the Lamiaceae family and native to central Asia, naturalized in central and eastern Europe and is cultivated around the world as a medicinal plant. Essential oils and extracts of Moldavian balm have been traditionally used as a painkiller for kidney complaints, toothache and colds. In addition, it has antimicrobial activities 1 , antirheumatic, antitumor, antimutagenic, antioxidant and antiseptic properties 2. Aerial parts of Moldavian balm are important sources of monoterpene glycosides, trypanocidal terpenoids, rosmarinic acid and flavonoids 3. Salinity stress is considered as one of the main environmental factors limiting plant distribution in their natural habitats 4. Soil salinity affects about 800 million hectares of arable land worldwide. Salinity stress causes major problems regarding plant growth, development and productivity, especially in arid and semi-arid regions of the world 5 manifested as changes in morphological, physiological and biochemical characteristics of plants, ion toxicity (Na + and Cl −), nutritional disorders and osmotic stress. These negative impacts significantly decrease plant

“…In this study, the trend of the chlorophyll content and that of the Fe content are the same, where the treatment with Fe-EDTA at pH 4.70 resulted in the highest chlorophyll content and simultaneously the greenest leaves. It was observed that supplemental Fe-EDTA at pH 4.70 increased the chlorophyll content and accordingly decreased chlorosis, which was in agreement with the findings of Nemati Lafmejani [ 29 ] and Mann [ 30 ]: a significant increase in the chlorophyll content with foliar application of Nano-Fe and FeSO 4 . It was worth noting that the leaves of plantlets grown in the control at pH 6.70, with Fe-DTPA at pH 4.70 and pH 5.70 displayed varying degrees of color change: leaves turned brown when grown in the control at pH 6.70, while the leaves grown with supplementary Fe-DTPA at pH 4.70 and pH 5.70 were metallically luster, and the degree of bronzing decreased with the increase of the pH when Fe-DTPA was supplemented.…”

Sorbus commixta is a valuable hardwood plant with a high economical value for its medicinal and ornamental qualities. The aim of this work was to investigate the effects of the iron (Fe) source and medium pH on the growth and development of S. commixta in vitro. The Fe sources used, including non-chelated iron sulfate (FeSO4), iron ethylenediaminetetraacetic acid (Fe-EDTA), and iron diethylenetriaminepentaacetic acid (Fe-DTPA), were supplemented to the Multipurpose medium with a final Fe concentration of 2.78 mg·L−1. The medium without any supplementary Fe was used as the control. The pH of the agar-solidified medium was adjusted to either 4.70, 5.70, or 6.70. The experiment was conducted in a culture room for six weeks with 25 °C day and night temperatures, and a 16-h photoperiod with a light intensity of 50 mmol·m−2·s−1 photosynthetic photon flux density (PPFD). Both the Fe source and pH affected the growth and development of the micropropagated plants in vitro. The leaves were greener in the pH 4.70 and 5.70 treatments. The tissue Fe content decreased with the increase of the medium pH. The leaf chlorophyll content was similar between plants treated with FeSO4 and those with Fe-EDTA. The numbers of the shoots and roots of plantlets treated with FeSO4 were 2.5 and 2 times greater than those of the control, respectively. The fresh and dry weights of the shoot and the root were the greatest for plants treated with Fe-EDTA combined with pH 5.70. The calcium, magnesium, and manganese contents in the plantlets increased in the pH 5.70 treatments regardless of the Fe source. Supplementary Fe decreased the activity of ferric chelate reductase. Overall, although the plantlets absorbed more Fe at pH 4.70, Fe-EDTA combined with pH 5.70 was found to be the best for the growth and development of S. commixta in vitro.

“…In this study, we observed that the Fe deficiency led to greatly reduced chlorophyll contents, and the chlorophyll content decreased with the decrease in the Fe content. It was illustrated that the utilization of supplementary FeSO 4 and Fe-EDTA could decrease chlorosis, which was in agreement with the findings in groundnut (Arachis hypogaea L.) and peppermint (Mentha piperita L.) [66,67]. Moreover, Fe deficiency caused reduction of the stomatal pores length, cuticular weight per unit surface, cuticular waxes, and stomatal turgor [68].…”

Hydrangea macrophylla is a popular perennial ornamental shrub commercially grown as potted plants, landscape plants, and cut flowers. In the process of reproduction and production of ornamental plants, the absorption of nutrients directly determines the value of the ornamental plants. Hydrangea macrophylla is very sensitive to the content and absorption of the micronutrient iron (Fe) that affects growth of its shoots. However, the physiological activity of Fe as affected by deficiency or supplementation is unknown. This work aimed at preliminary exploring the relationship between Fe and photosynthesis, and also to find the most favorable iron source and level of pH for the growth of H. macrophylla. Two Fe sources, non-chelated iron sulfate (FeSO4) and iron ethylenediaminetetraacetic acid (Fe-EDTA), were supplemented to the multipurpose medium with a final Fe concentration of 2.78 mg·L−1. The medium without any Fe supplementation was used as the control. The pH of the agar-solidified medium was adjusted to either 4.70, 5.70, or 6.70, before autoclaving. The experiment was conducted in a culture room for 60 days with 25/18 °C day and night temperatures, and a 16-hour photoperiod provided at a light intensity of 50 mmol·m−2·s−1 photosynthetic photon flux density (PPFD) from white light-emitting diodes. Supplementary Fe increased the tissue Fe content, and leaves were greener with the medium pH of 4.70, regardless of the Fe source. Compared to the control, the number of leaves for plantlets treated with FeSO4 and Fe-EDTA were 2.0 and 1.5 times greater, respectively. The chlorophyll, macronutrient, and micronutrient contents were the greatest with Fe-EDTA at pH 4.70. Furthermore, the Fe in the leaf affected the photosynthesis by regulating stomata development, pigment content, and antioxidant system, and also by adjusting the expression of genes related to Fe absorption, transport, and redistribution. Supplementation of Fe in a form chelated with EDTA along with a medium pH of 4.70 was found to be the best for the growth and development of H. macrophylla plantlets cultured in vitro.
