“…This circumstance elaborates on the underlying mechanism through which PPFD compensated for N uptake under N constraint. Concurred with our results, the positive effect of PPFD on root biomass reported on lettuce 14 and chrysanthemum 41 . Regardless of PPFD, increase in N concentration reduced the partitioning of biomass to flowers.…”

“…The main absorption spectra of the chlorophyll pigments are in the range of blue and red light, therefore, these two spectra are mainly used for plant production in controlled environments 13 . Besides light quality, the intensity of the light also exerts a broad range of physiological effects on plant growth and performance 14 – 16 , including, N uptake and allocation 17 .…”

Identifying environmental factors that improve plant growth and development under nitrogen (N) constraint is essential for sustainable greenhouse production. In the present study, the role of light intensity and N concentrations on the biomass partitioning and physiology of chrysanthemum was investigated. Four light intensities [75, 150, 300, and 600 µmol m−2 s−1 photosynthetic photon flux density (PPFD)] and three N concentrations (5, 10, and 15 mM N L−1) were used. Vegetative and generative growth traits were improved by increase in PPFD and N concentration. High N supply reduced stomatal size and gs in plants under lowest PPFD. Under low PPFD, the share of biomass allocated to leaves and stem was higher than that of flower and roots while in plants grown under high PPFD, the share of biomass allocated to flower and root outweighed that of allocated to leaves and stem. As well, positive effects of high PPFD on chlorophyll content, photosynthesis, water use efficiency (WUE), Nitrogen use efficiency (NUE) were observed in N-deficient plants. Furthermore, photosynthetic functionality improved by raise in PPFD. In conclusion, high PPFD reduced the adverse effects of N deficiency by improving photosynthesis and stomatal functionality, NUE, WUE, and directing biomass partitioning toward the floral organs.

“…Prior study noted the importance of optimizing light intensity for accurate estimation of water productivity that would become imperative in planning ang managing irrigation practice. Results of this study showed that growth parameters such as fresh weigh, dry weight, and leaf area were improved by increasing light intensity together with carbon dioxide concentration (Esmaili et al, 2021). Another study about dependency of growth of lettuce plants to light intensity emphasized that exposure to higher light intensities causing faster development of photosynthesis system was dependent on the leaf developmental stages (Ghorbanzadeh et al, 2020).…”

Land and water resources, climate change, and disaster risks significantly affect the agricultural sector. An effective solution for growing crops to improve productivity and optimize the use of resources is through controlled-environment agriculture (CEA). Evapotranspiration (ET) is an important greenhouse crop attribute that can be optimized for optimum plant growth. Light intensity and radiation are significant for controlling ET. To address this challenge, this study successfully determined the properties of optimum artificial light for minimum evapotranspiration rate of head development-stage and harvest-stage lettuce under light-period and dark-period using genetic programming and bio-inspired algorithms namely, grey wolf optimization (GWO), whale optimization algorithm (WOA), dragonfly algorithm (DA), and moth flame optimization (MFO). MFO provided the optimized global solution for the configured models. Results showed that head development-stage lettuce requires higher light intensity with lower visible to infrared radiation ratio (Vis/IR) than harvest-stage lettuce when exposed to light. On the other hand, harvest-stage lettuce requires higher light intensity with lower Vis/IR than head development-stage under dark-period respiration reaction. Findings of this study can be utilized in growing and improving yield crops in controlled-environment agriculture.

“…Therefore, the optimum growth light intensity for light use efficiency was clearly the 300 µmol m −2 s −1 PPFD. In lettuce, the optimum growth light intensity was 600 µmol m −2 s −1 PPFD 16,17,[41][42][43][44] , while for Aloe vera L. it was 50% of sunlight as compared to 75 or 100% 44 . F v /F m was generally not affected by TiO 2 nanoparticle spray, except for an increase noted at 75 µmol m −2 s −1 PPFD.…”

Due to the photocatalytic property of titanium dioxide (TiO2), its application may be dependent on the growing light environment. In this study, radish plants were cultivated under four light intensities (75, 150, 300, and 600 μmol m−2 s−1 photosynthetic photon flux density, PPFD), and were weekly sprayed (three times in total) with TiO2 nanoparticles at different concentrations (0, 50, and 100 μmol L−1). Based on the obtained results, plants used two contrasting strategies depending on the growing PPFD. In the first strategy, as a result of exposure to high PPFD, plants limited their leaf area and send the biomass towards the underground parts to limit light-absorbing surface area, which was confirmed by thicker leaves (lower specific leaf area). TiO2 further improved the allocation of biomass to the underground parts when plants were exposed to higher PPFDs. In the second strategy, plants dissipated the absorbed light energy into the heat (NPQ) to protect the photosynthetic apparatus from high energy input due to carbohydrate and carotenoid accumulation as a result of exposure to higher PPFDs or TiO2 concentrations. TiO2 nanoparticle application up-regulated photosynthetic functionality under low, while down-regulated it under high PPFD. The best light use efficiency was noted at 300 m−2 s−1 PPFD, while TiO2 nanoparticle spray stimulated light use efficiency at 75 m−2 s−1 PPFD. In conclusion, TiO2 nanoparticle spray promotes plant growth and productivity, and this response is magnified as cultivation light intensity becomes limited.
