“…As a result, this result indicates that pre-harvest nutrient solution replacement with tap water within 72 h was not stressful and had no adverse effect on crop quality. Phenolic biosynthesis in plants is triggered by H2O2 [30]. However, H2O2 was probably reduced by vitamin C as vitamin C in this experiment was decreased for use in the reduction of H2O2.…”

Lettuce (Lactuca sativa L.) is a high-value nutritional food for human consumption, rich in minerals and vitamins. However, people are still concerned about the residues of nitrate content in hydroponic lettuce. Pre-harvesting by replacing nutrient solution with tap water is one of several factors that can help to reduce nitrate content and improve the quality of hydroponic lettuce. Therefore, this study focused on the effect of pre-harvest periods by replacing nutrient solution with tap water on nitrate and quality in hydroponic lettuce. This experiment was performed by replacing nutrient solution with tap water in a hydroponic system for 0 h, 24 h, 48 h, and 72 h before harvesting the lettuce product. Nitrate, vitamin C, phenolic, and soluble sugar contents were determined. The results showed that nitrate content was lowest under pre-harvest conditions for 72 h (19 mg/g dry weight, 63% reduction), but it was not significantly different for 48 h (20 mg/g dry weight, 61% reduction). The vitamin C content was significantly decreased after pre-harvesting for 72 h (5.3 µg/100 g, 30% reduction). The soluble sugar content was significantly increased and reached its highest content after pre-harvest for 48 h (3.3 mg/100 g, 105% increase), but there was no significant difference at 72 h (3.2 mg/100 g, 98% increase). Although the phenolic content decreased slightly, there was no significant difference among the treatments. In conclusion, nitrate contents were reduced the lowest, and soluble sugar contents were increased the highest after pre-harvest for 48 h. Vitamin C and phenolic contents were slightly decreased after pre-harvest periods by replacing the nutrient solution with tap water.

“…The reason is probably, the vitamin C content is accumulated in the cytosol before the pre-harvest experiment. Following the investigation, lettuce may use vitamin C to reduce H2O2 to H2O [28][29], where H2O2 is normally induced by pre-harvest stress [30].…”

“…This suggests that Rubisco's activity status is primarily regulated by H 2 O 2 , potentially by the Rubisco enzyme (Jiang et al., 2012). As a result, H 2 O 2 ‐primed plants maintain higher photosynthetic rates and accumulate more carbohydrates, which is crucial for growth and stress tolerance (S. Wang et al., 2022). In support of these findings, Jiang et al.…”

“…By regulating ion transport, H 2 O 2 ‐primed plants can minimize the toxic effects of excessive Na + accumulation and maintain cellular ion balance (Chattha et al., 2022; Silva et al., 2020). H 2 O 2 priming can also trigger the synthesis of secondary metabolites, including phytohormones, phenolic compounds, and flavonoids (Karimi et al., 2020; W. Wang et al., 2022). These metabolites play crucial roles in plant defense against salinity stress.…”

Salinity stress is a growing concern for agriculture, as soil salinization is increasing worldwide and seriously affects global agricultural production and food security. How to minimize the adverse effects of salinity stress and meet the food needs of the growing human population becomes an urgent problem. Conventional techniques in agriculture and recently modern plant science have limitations; therefore, alternative technologies such as hydrogen peroxide (H2O2) priming have emerged as promising solutions. The findings highlight that H2O2 priming enhances antioxidant defenses, regulating the balance between reactive oxygen species production and scavenging. Furthermore, H2O2 priming promotes osmotic adjustment by stimulating the accumulation of osmoprotectants, maintaining cellular water status under salinity conditions. The review also discusses how H2O2 priming modulates gene expression and signaling processes, causing stress‐responsive genes and transcription factors activation. Moreover, H2O2 priming helps to preserve chloroplast integrity and photosynthetic efficiency, mitigating the detrimental impacts of salt stress on plant development and productivity. Overall, the collective knowledge gathered here, covering various aspects of the H2O2 priming phenomenon, may facilitate the design and conduct of future research on plant tolerance to salinity or other abiotic stresses. However, future research needs to focus on elucidating how priming can be applied on a large scale to diverse plants, understanding biochemical and molecular mechanisms of H2O2 priming for precise and reliable applications of this approach, and figuring out the potential benefits of in vitro priming (H2O2) technology in plant science.

“…The reduction of phenolic compounds in plants was closely related to the decreased PAL activity. Chalcone synthase (CHS), flavanone 3-hydroxylase (F3H), dihydroflavonol-4 reductase (DFR), flavonoid 3′,5′-hydroxylase (F35H), and UDP-glucose: flavonoid 3- O -glucosyltransferase (UFGT) are also key enzymes involving in the biosynthesis of different phenolic compounds, such as phenolic acids, flavonoids, and anthocyanins ( Daryanavard et al, 2023 , Wang et al, 2022a ). The phenolic metabolism is a complex process, and phenolic accumulation in plants is generally caused by various biotic and abiotic stresses ( Yang et al, 2023 , Zlotek et al, 2014 ).…”
