Opisthopappus longilobus (Opisthopappus) and its descendant species, Opisthopappus taihangensis, commonly thrive on the Taihang Mountains of China. Being typical cliff plants, both O. longilobus and O. taihangensis release unique aromatics. To determine the potential differentiation and environmental response patterns, comparative metabolic analysis was performed on O. longilobus wild flower (CLW), O. longilobus transplant flower (CLT), and O. taihangensis wild flower (TH) groups. Significant differences in the metabolic profiles were found, not within O. longilobus, but between O. longilobus and O. taihangensis flowers. Within these metabolites, twenty-eight substances related to the scents were obtained (one alkene, two aldehydes, three esters, eight phenols, three acids, three ketones, three alcohols, and five flavonoids), of which eugenol and chlorogenic were the primary aromatic molecules and enriched in the phenylpropane pathway. Network analysis showed that close relationships occurred among identified aromatic substances. The variation coefficient (CV) of aromatic metabolites in O. longilobus was lower than O. taihangensis. The aromatic related compounds were significantly correlated with the lowest temperatures in October and in December of the sampled sites. The results indicated that phenylpropane, particularly eugenol and chlorogenic, played important roles in the responses of O. longilobus species to environmental changes.

“…Nitrogen (N) is one of the essential macronutrients for plant growth and the uptake of available N in the soil is an important indicator of plant growth. [1,2] It is one of the major components of proteins, nucleic acids, lipids, and some hormones in plants. N contributes 40-50 % of crop yield.…”

In the current research, nitrification inhibitors such as 2,5‐dichloroaniline, ammonium thiosulphate, and their combination (1:1) were used to slow down the nitrification process to increase the nitrogen availability for crops. The various levels of 0.1, 0.25, and 0.5 % were used for each inhibitor on three types of soil. Leachates were collected from each treatment, add 1ml of 0.1 % chromotropic acid solution and 6 mL of concentrated sulfuric acid, swirled in the flask, and left at room temperature, yellow color was developed after 45 minutes. Then absorbance reading was noted for each sample by spectrophotometer at the wavelength of 430 nm. NO3‐ ‐N content was determined by the standard curve method. From inhibitors, the combination of both inhibitors shows minimum NO3‐ ‐N content as 154.29 and 112.83 ppm than other chemicals for 2nd and 14th days respectively. From soil, Sheikhupura soil shows minimum NO3‐ ‐N in the leachate as 176.26 (2nd day) and 105.03 ppm (14th day) as compared to other soils. From the levels, 0.25 % shows minimum NO3‐ ‐N as 118.05 (2nd day) and 63.18 ppm (14th day) as compared to other levels. The combination (1:1) and the level 0.25 % were found more suitable to reduce the nitrification process in Sheikhupura soil.

“…Arginine is a proteinogenic amino acid that has the highest nitrogen-to-carbon ratio and is an essential amino acid for protein synthesis, a precursor for proline, polyamines and nitric oxide (NO), and is involved in many plant metabolisms (Winter et al, 2015). Exogenous application of arginine allows the direct uptake of organic nitrogen resources by plants, enhancing nitrogen accumulation (Näsholm et al, 2009) and increasing yield and quality (Wang et al, 2021). In tomatoes, foliar applications of arginine improved yield and quality components, such as lycopene, vitamin C, soluble sugar contents and nitrogen accumulation (Wang et al, 2021).…”

In tomatoes, foliar applications of arginine improved yield and quality components, such as lycopene, vitamin C, soluble sugar contents and nitrogen accumulation (Wang et al, 2021). Additionally, it can protect tomatoes from transient heat stress, probably due to decreasing the hydrogen peroxide level to avoid oxidative imbalance with an increased concentration of arginine application (Conceição et al, 2021).…”

Importance of the work: Green perilla is a medicinal plant rich in nutrients and bioactive compounds, especially at the microgreen stage. Enhancing the productivity and quality of green perilla microgreens can upgrade their product value for growers and provide increased variety for consumers regarding healthy products. Objectives: To investigate the application of light-emitting diode (LED) illumination along with amino acid supplements, such as L-arginine to promote the growth, productivity and quality of green perilla microgreens. Materials & Methods:The experimental design was a 4×4 factorial completely randomized design with two factors consisting of: 1) L-arginine concentrations (0 mM, 1.25 mM, 2.5 mM or 5 mM); and 2) LED lighting (white [W], red [R], blue [B] or red:blue 70:30 [70R:30B]). The plants were grown under a light intensity of 80 ± 5 μmol/m 2 /s photosynthetic photon flux density, with an air temperature of 25°C and relative humidity of 65-70%. Results: The 70R:30B LED lighting promoted not only the best growth (leaf fresh weight and leaf area) but also the best quality (nitrogen, crude protein, vitamin C, total phenolics and total flavonoids contents) of the microgreens. In addition, the white LEDs enhanced total chlorophyll, total carotenoids, nitrogen and crude protein. Furthermore, applying 5.0 mM of L-arginine improved the quality of the green perilla microgreens (total chlorophyll, carotenoids nitrogen and crude protein contents and 2,2-diphenyl-1-picrylhydrazyl scavenging activity). Since there was an interaction between the two factors, the combination of 5 mM L-arginine and the 70R:30B illumination significantly stimulated the plant height, stem fresh weight and total flavonoid contents of the microgreen product. Main finding: Applying 70R:30B LEDs with 5 mM L-arginine was appropriate for green perilla microgreen production.
