Controlled environment agriculture (CEA) is critical for achieving year-round food security in many regions of the world. CEA a resource-intensive endeavor, with lighting consuming large fraction energy. To lessen burden on grid and save costs, an extended photoperiod strategy can take advantage off-peak time-of-day options from utility suppliers. However, extending limits crop production morphologically physiologically if pushed too long. Here, we present continuous-light dynamic light-emitting diode (LED) (involving changes spectra, intensity, timing), that overcomes these limitations. We focused tomato, well described photoperiodic injury–sensitive species, mini-cucumber, injury-tolerant species to first assess morphological responses under control (16-h photoperiod, unchanging spectrum), constant (24-h two variations LED strategy, 1 “day”, 3-h “peak”, 8-h “night” spectra) 2 (20-h 5-h 4-h spectra).

These results suggest tolerance involves sustained photoperiods.

Vertical farming is considered to be a key enabler for transforming agrifood systems, especially in or nearby urbanized areas. systems (VFS) are advanced indoor cropping that allow highly intensified and standardized plant production. The close control of environmental parameters makes crop production stable repeatable, ensuring year-round uniform product quality quantity irrespective location. However, due continuous changes physiology development, as well frequent electricity prices, the optimum conditions its associated costs can change within days even minutes. This it beneficial dynamically adjust setpoints light (intensity, spectrum, pattern, daylength), CO 2 , temperature, humidity, air flow, water nutrient availability. In this review, we highlight effects dynamic growth have on processes, including improvements photosynthetic gas exchange, transpiration, organ growth, interception, flowering, quality. Our novel findings based modeling experimentation demonstrate daily intensity pattern responds prices save without reducing biomass. Further, argue smart, VFS climate management requires feedback mechanisms: several mobile immobile sensors could work combination continuously monitor crop, generating data feeds into models, which, turn, generate setpoints. addition, posit breeding environment at very early stage traits specialized environment. We envision loop between management, monitoring, trait selection genotypes these conditions.

This study examines the impact of daily light integral (DLI) from artificial lighting on tomato seedlings cultivated in plant factories. By adjusting intensity and photoperiod LED, research explored effects varying DLIs morphology, growth, physiological characteristics, photosynthetic pigment content, chlorophyll fluorescence seedlings. The optimal DLI enhanced seedling biomass, root vitality, antioxidant enzyme activity, synthesis. Excessively high or inhibited photosynthesis, potentially leading to photoinhibition. identified 13.2 mol·m−2·d−1 through gradients Exp 1 2. Based these findings, 3 established growth conditions by setting different intensities photoperiods under most suitable DLI, which were a 200 μmol·m−2·s−1 18 h. These results provide significant guidance for optimizing environment cultivation factories, helping improve energy utilization efficiency.

Floral transition from the vegetative to reproductive stages is precisely regulated by both environmental and endogenous signals. Among these signals, photoperiod one of most important factors for onset flowering. A florigen, FLOWERING LOCUS T ( FT ) in Arabidopsis , has thought be a major hub photoperiod-dependent flowering time regulation. Expression levels likely correlates with potence Under long days (LD), mainly synthesized leaves, protein moves shoot apical meristem (SAM) where it functions turns induces Recently, been reported that grown under natural LD condition flowers earlier than laboratory condition, which red (R)/far-red (FR) ratio light sources determines expression levels. Additionally, profile changes response combinatorial effects FR photoperiod. orthologs exist plants are conserved. Although molecular mechanisms underlying photoperiodic transcriptional regulation have studied several plants, such as rice, however, dynamics profiles less spotlighted.

It is well known that pollinators play a crucial role in crop production systems. Pollination services have high economic importance worldwide, because they ensure higher fruit and quality. Insects outstanding vision all make use of colour when searching for flowers to feed on pollen nectar. Many studies the sensitivity pollinator photoreceptors shown (including Apidae species Syrphidae species) are specifically sensitive light spectrum ranging from UV (300nm) yellow/red (650nm) struggle red far-red (>650nm). Contrasting colours (target versus background) also major recognition flowers. Based results this study, it can be concluded LED lighting with different spectra affects foraging activity pollinators. Greenhouse growers should take into consideration by increasing ratio their lighting, may difficulties finding flowers, leading lower pollination efficiency. This research increases our understanding effect activity, which necessary providing best advice balance optimization plant growth services.
