In recent years, the use of priming agents, such as silicon, melatonin, salicylic acid, glycine betaine, and ascorbic acid has gained significant attention for their role in mitigating abiotic stresses across various plant species. While previous research been conducted on individual impact metal stress resistance among crop species, combined effects context heavy stressed conditions remain underexplored. Wheat (Triticum aestivum L.) seedlings was grown under toxic concentration copper (Cu) i.e., 100 µM which were applied with hydroponic 21 days. The outcomes indicated that Cu nutrient solution notably reduced growth biomass, photosynthetic pigments, gas exchange attributes. However, also induced oxidative plants by increasing malondialdehyde (MDA), hydrogen peroxide (H2O2) increased compounds enzymatic non-enzymatic antioxidants, health risk index (HRI) gene expression sugar content. Furthermore, a increase proline metabolism, AsA-GSH cycle, pigmentation cellular components observed. Although, application different showed characteristics, compounds, decreased HRI. addition, agents enhanced fractionation metabolism cycle T. seedlings. These results open new insights sustainable agriculture practices hold immense promise addressing pressing challenges contamination agricultural soils.

Polyphenolics in plants exist free, soluble-bound, and insoluble-bound structural forms. The concentration of these forms depends on the plant’s developmental stage, tissue type, soil water availability, food preparation methods. In this study, for first time, effects growth temperature (RT—room temperature—23 °C day/18 night, HT—high temperature—38 day/33 LT—low temperature—12 day/7 night) variations polyphenolic forms—free, soluble-bound (esterified glycosylated), insoluble-bound—in broccoli (Brassica oleracea L. convar. botrytis (L.) Alef. var. cymosa Duch.) microgreens were investigated. Using spectrophotometric, RP-HPLC, statistical analyses, it was found that highest amount total phenolics (TP) present esterified form, regardless at which they grown (63.21 ± 3.49 mg GAE/g dw RT, 65.55 8.33 HT, 77.44 7.82 LT). LT significantly increased free (from 13.30 2.22 RT to 18.33 3.85 dw) soluble TP 63.21 dw), while HT glycosylated 14.85 1.45 17.84 1.20 dw). also enhanced flavonoids, tannins, hydroxycinnamic acids, flavonols. other hand, TP, flavonols, phenolic decreased tannins. According ABTS method, induced antioxidant potential forms, capacity only. FRAP Also, based assays, polyphenolics showed higher than any form. Principal component analysis form had a greater impact temperature. Hierarchical clustering RT-, HT- LT-broccoli most similar their polyphenolics, but differed distinct overall. conclusion, specific shifts capacity.
