Light is a vital regulator of photosynthesis, energy production, plant growth, and morphogenesis. Although these key physiological processes are well understood, the effects light quality on pigment content, oxidative stress, reactive oxygen species (ROS) antioxidant defense systems, biomass yield plants remain largely unexplored. In this study, we applied different light-emitting diode (LED) treatments, including white light, red blue red+blue (1:1) combination, to evaluate traits mentioned above in alfalfa (Medicago sativa L.). Fluorescence staining showed that significantly triggered stress indicators compared while combined treatment reduced ROS (O2•−, H2O2) intensity seedlings. Interestingly, boosted seed germination rate (%), maximum photochemical quantum PSII (Fv/Fm), leaf greenness (SPAD score), photosynthetic levels (chlorophyll a, chlorophyll b, carotenoids), The and/or (red+blue) treatments regulated enzymes (SOD, CAT, APX, GR) expression genes related ascorbate–glutathione (AsA-GSH) pathway, monodehydroascorbate reductase (MsMDHAR), dehydroascorbate (MsDHAR), ascorbate peroxidase (MsAPX), glutathione (MsGR). These results indicate crucial for regulating morphological, physiological, molecular linked improvement. findings suggest new approach enhancing adaptation, as morphological agronomic yield, forage legumes through light-quality-mediated

In modern agriculture, Controlled environment agriculture (CEA) stands out as a contemporary production mode that leverages precise control over environmental conditions such nutrient, temperature, light, and other factors to achieve efficient high-quality agricultural production. Numerous studies have demonstrated the efficacy of manipulating these in short period before harvest enhance crop yield quality CEA. This comprehensive review aims provide insight into various pre-harvest practices employed CEA, including nutrient deprivation, supply, manipulation light environment, application exogenous hormones, with objective improving horticultural crops. Additionally, we propose an intelligent management system cultivate integrates sensor technology, data analysis, control, enabling customization specific strategies based on producers’ requirements. The envisioned holds potential quality, increase yield, reduce resource wastage, offer innovative ideas technical support for sustainable development

The increasing demand for bioactive compounds from plants has spurred the exploration of innovative strategies to enhance their production. This review focuses on three advanced methodologies: elicitation, metabolic engineering, and using biosynthesized nanoparticles. Elicitation, through application abiotic biotic stressors, stimulates plant defense mechanisms, significantly boosts secondary metabolite Metabolic engineering further refines this process by genetically modifying key pathways redirect resources towards synthesis valuable compounds. Additionally, metallic oxide nanoparticles offer a sustainable method growth These act not only as elicitors, but also catalyze processes improve efficiency compound synthesis. Despite significant advancements, challenges remain in optimizing these approaches large-scale agricultural application, particularly understanding precise interactions between systems. integration holds great potential agriculture development high-value phytochemicals. Future research should focus unraveling complex mechanisms behind refining methods commercial use, ensuring environmental economic sustainability.

Lighting is a fundamental driver of plant productivity in controlled-environment agriculture (CEA), directly affecting physiological processes, resource efficiency, and sustainability. This study evaluates the effects distinct lighting systems, industrial Light-Emitting Diodes (iLEDs), horticultural LEDs (hLEDs), high-pressure sodium (HPS) lamps, controls (no supplemental light), each providing unique light spectra, on cucumber (Cucumis sativus L.) growth, physiology, environmental impact under controlled intensity 250 µmol m−2 s−1 commercial CEA setup. The results indicated that iLEDs enhance intrinsic water use efficiency (35.65 CO2/mol H2O) reduce transpiration, reflecting superior use. Electrophysiological measurements significantly more stable stress responses plants subjected to hLEDs as compared HPS control treatments, indicating effectiveness LED spectra mitigating stress-related impacts. Furthermore, compact growth shorter stem internodes were observed well hLEDs, highlighting spectral photomorphogenesis, likely caused by balanced spectrum. achieved highest yield (42.86 kg m−2) but at significant cost, with 342.65 CO2e emissions 204.29 for iLEDs, competitive 38.84 m−2. Economic analysis revealed also offered most cost-effective solution due lower energy consumption extended lifespan. focused interaction between photosynthetic performance, resilience, advancing sustainable strategies energy-efficient food production systems.
