Abstract In vitro growing of Melaleuca can contribute to the cloning superior genotypes. Studies on factors affecting micropropagation are necessary, especially those using recent technologies, such as light-emitting diodes (LEDs). This study aimed at better understanding effects wavelengths development and physiology cultivated in vitro, well interaction LED with N6-Benzylaminopurine (BAP), main cytokinin used micropropagation. The BAP wavelengths, their interaction, had a strong influence most variables analyzed, altering chlorophyll concentrations plants changing different culture medium, pH, EC, levels Ca2+, Mg2+ P media nutrient accumulation shoots. results demonstrated that adding cultivation increase number shoots, which resulted greater fresh dry mass, reduction height contents, complete inhibition adventitious rooting, higher consumption Mg lower Ca from media, contents Fe P, S, Mn, Cu B tissues.

In this study, for first time, the efficiency of yield and fruit quality pink tomato cultivar ‘Tomimaru Muchoo’ was studied in hydroponic cultivation with top interlighting LEDs (light-emitting diodes) diffusion glass (DGlass) to cover glasshouse roof (LED+LED+DGlass). DGlass also tested only lighting by sodium lamps (HPS+DGlass). The control, which had no (HPS, high-pressure sodium), a crop from above, where covered conventional glass. Selected parameters plant growth development, photosynthetic activity, chemical composition were analysed. Tomato fruits evaluated their physical characteristics as well sensory quality. LED+LED+DGlass-supplemented plants shortest fruiting stems, higher dry matter leaves, Mg2+ ion concentration, apparatus activity (PI, PSII performance index) compared control (HPS). More light under conditions without (HPS+DGlass LED+LED+DGlass) increased leaf thickness number mesophyll layers. highest obtained LED+LED+DGlass combination growing technology Fruits characterised total soluble solids (TSS), carotenoids, ascorbic acid content most favourable sugar/acid ratio. evaluation, these sweeter less acidic than other combinations. results confirm significant influence on growth, yield.

High demands of Kappaphycus alvarezii in markets require commercial scale the seaweed’s cultivation and large amount seedlings. One best ways to overcome seedling scarcity is by using seaweed micropropagation. This study was carried out produce K. type Giant Tambalang tissue culture micropropagation technique. The axenic explants were inoculated into petri dishes with plant agar 1.5% agarose supplemented Provasoli’s enriched seawater (PES). cultured at 25 °C ± 1°C under cool white LED light (Culture room 1(CR1)) red blue lights 2 (CR2)) 17.55 µmol m-2s-1 20.28 m-2s-1, respectively. After 6 days, results showed that method treating thallus 70% alcohol for 5 seconds sterile artificial able induced calluses CR1 rate callus formation 53.33% (plant agar) 46.67% (agarose).

Researchers and companies are placing increasing importance on sustainability to fight climate change. This study analyzes the of hotel installation, photovoltaic (PV) solar panels, transition from traditional lighting light-emitting diode (LED) bulbs. The results show that for PV system, NPV (net present value) varied between 3191 11,959 kTND/kW installation panels has a positive 100% in case high market scenario 79–84% with reduced activity. Regarding energy optimization, use LED bulbs generates an 346 713 TND/bulb, depending self-consumption cost electricity. Ecological studies installing would reduce carbon dioxide emissions by 424 gCO2eq/kWh, or 61 tCO2eq/year. Furthermore, social evaluations have shown renewable optimization point view ecological transition. In conclusion, green investments improve hotels. However, fully exploit this potential, change consumer attitudes is needed. Hotels must continue promote their efforts while making guests aware eco-friendly choices. Only combined approach, involving both hoteliers guests, will achieve sustainable sector. objective article therefore examine multidisciplinary interactions development highlighting inherent opportunities approach success hospitality Our methodological combines theoretical numerical study. These play major role projects due economic, environmental, technical, technological contributions, which proves address holistic way.

The dependence of agriculture on water availability is an important premise justifying attempts to enhance use efficiency for plant production. Photosynthetic efficiency, directly impacts biomass production, dependent both and the quality quantity light. Understanding how these factors interact crucial improving crop yields. Many overlapping signalling pathways functions common bioactive molecules that shape responses deficit light have been identified discussed in this review. Separate or combined action environmental include generation reactive oxygen species, biosynthesis abscisic acid, stomatal functioning, chloroplast movement alterations levels photosynthetic pigments molecules. Plant response depends intensity its characteristics, with differentiated from UV, blue, red bands determining strength synergistic antagonistic nature interactions. Despite significance, effects remain insufficiently explored. findings highlight potential optimising horticultural production through controlled conditions regulated irrigation. Future research should assess manipulation strategies resource nutritional value.
