“…Leaf area is a key factor that determines the amount of photoassimilates produced by crops and thus, it substantially affects their growth, development, and productivity. A large LA is essential for high radiation interception [56]. Generally, plants with a greater LA show a higher photosynthetic capacity; consequently, LA is important for producing plants with optimal quality and the capacity for vigorous establishment in the field [57,58].…”

“…According to Hunt [26], for forest species such as Douglas-fir (Pseudotsuga menziesii), lodgepole pine (Pinus contorta), and white spruce (Picea glauca), a value greater than or equal to 0.20 is considered to indicate that a plant meets quality standards. However, some researchers suggest that DQI calibration tests should be established for each of the forest species of interest [39,56].…”

“…Furthermore, when the LAI is low, the moisture level of the microclimate inside the plant canopy decreases, which may reduce the presence of pathogenic microorganisms in the crop canopy. Considering that the LAI of many crops is high, Marcelis et al [56] have proposed that horticultural crop yields may be increased by limiting leaf formation when a certain LA has been reached (a LAI of approximately 3 to 4 m 2 m −2 ). This excludes herbaceous crops with leaves as the harvestable products (Equation ( 5)).…”

Plant quality and survival prediction tools are useful when applied in the field in different agricultural sectors. The objectives of this study were to conduct a review and bibliometric analysis of the Dickson Quality Index (DQI) as a key plant quality indicator and with respect to its scientific applications. A third objective was to identify the main morphological and physiological parameters used in plant production research. The methodology and findings of 289 scientific articles were analysed based on the morphological, physiological, and mathematical parameters used as plant quality indicators in research on forest, medicinal, horticultural, aromatic, and ornamental species. During the last 10 years, the number of publications that have used the DQI as a plant quality parameter has increased by 150%, and Brazilian researchers stand out as the most frequent users. Forestry is the discipline where quality parameters and their biometric relationships are most often used to facilitate intensive plant production. Use of the DQI increases the certainty of prediction, selection, and productivity in the plant production chain. The DQI is a robust tool with scientific application and great potential for use in the preselection of plants with high quality standards among a wide range of plant species.

“…Specific light spectra may be applied during plant raising to form traits that are desirable for later production, which may occur in greenhouses or the open field. Under full sunlight, plants will experience a longer duration of high light (HL) intensity or a high frequency of HL intensity and low light (LL) intensity transitions, due to variations of the solar angle, cloud cover, overlapping leaves, and greenhouse structures ( Li et al, 2014 , 2016 ; Marcelis et al, 2018 ). Plants need to maximize the efficiency of light energy used for photosynthesis while minimizing deleterious effects associated with exposure to HL intensity.…”

“…Plant growth, to a large extent, depends on photosynthetic performance. When exposed to full sunlight, plants often experience dynamic light intensities, such that net photosynthesis rate ( A ; μmol m –2 s –1 ) is rarely at a steady state ( Kaiser et al, 2015 ; Li et al, 2016 ; Marcelis et al, 2018 ). When light intensity impinging on a shade-adapted leaf increases suddenly, A may take 10–30 min to reach a steady state, such that it might not reach a steady state before light intensity decreases again ( McAusland and Murchie, 2020 ).…”

Acclimating Cucumber Plants to Blue Supplemental Light Promotes Growth in Full Sunlight

et al. 2021

Raising young plants is important for modern greenhouse production. Upon transfer from the raising to the production environment, young plants should maximize light use efficiency while minimizing deleterious effects associated with exposure to high light (HL) intensity. The light spectrum may be used to establish desired traits, but how plants acclimated to a given spectrum respond to HL intensity exposure is less well explored. Cucumber (Cucumis sativus) seedlings were grown in a greenhouse in low-intensity sunlight (control; ∼2.7 mol photons m–2 day–1) and were treated with white, red, blue, or green supplemental light (4.3 mol photons m–2 day–1) for 10 days. Photosynthetic capacity was highest in leaves treated with blue light, followed by white, red, and green, and was positively correlated with leaf thickness, nitrogen, and chlorophyll concentration. Acclimation to different spectra did not affect the rate of photosynthetic induction, but leaves grown under blue light showed faster induction and relaxation of non-photochemical quenching (NPQ) under alternating HL and LL intensity. Blue-light-acclimated leaves showed reduced photoinhibition after HL intensity exposure, as indicated by a high maximum quantum yield of photosystem II photochemistry (Fv/Fm). Although plants grown under different supplemental light spectra for 10 days had similar shoot biomass, blue-light-grown plants (B-grown plants) showed a more compact morphology with smaller leaf areas and shorter stems. However, after subsequent, week-long exposure to full sunlight (10.7 mol photons m–2 day–1), B-grown plants showed similar leaf area and 15% higher shoot biomass, compared to plants that had been acclimated to other spectra. The faster growth rate in blue-light-acclimated plants compared to other plants was mainly due to a higher photosynthetic capacity and highly regulated NPQ performance under intermittent high solar light. Acclimation to blue supplemental light can improve light use efficiency and diminish photoinhibition under high solar light exposure, which can benefit plant growth.
