“…Various plant photoreceptors can sensitively perceive light signals and transmit them to the core oscillators of the biological clock, which integrates various external environmental signals for adaptive regulation, the primary way in which plant growth and development are regulated [10][11][12]. Blue light, which has a wavelength range of 400-500 nm, is involved in the regulation of plant photomorphogenesis, photosynthesis, and the synthesis of active substances [13][14][15]. Blue light receptors have been shown to be involved not only in these above-mentioned processes but also in the regulation of the plant photoperiod, phototropism, stress response, and organ development [16,17].…”

Camellia oleifera Abel., which produces fruits of high comprehensive utilization value, is an important woody oil tree in China. ZEITLUPE (ZTL) is a blue light receptor and clock component protein that is involved in various physiological and biochemical processes. However, the expression pattern and function of C. oleifera ZTL (CoZTL) remain unclear. In this study, the coding sequence of the CoZTL gene was isolated and the protein function was explored using bioinformatics and expression analyses and heterologous expression techniques. The results showed that the CoZTL protein was highly conserved during evolution and was on the same branch of the evolutionary tree as the ZTL proteins from Ipomoea nil and Nicotiana attenuata. CoZTL was mainly expressed in the fruit shells and stems of C. oleifera, and its expression level fluctuated greatly during flower bud development. Transgenic CoZTL-overexpressing Arabidopsis plants showed delayed flowering under long-day conditions as well as light-dependent promotion of hypocotyl elongation. Furthermore, yeast two-hybrid library screening revealed that seven C. oleifera proteins (CoAAT, Coβ-GAL, CoLAT52-like, CoCAR4-like, CoAO, CoUQCC1, and CoADF 2) interacted with CoZTL. Our results indicate that CoZTL plays an important role in C. oleifera flowering and hypocotyl growth.

“…In another publication, Frąszczak (2016) grew dill under different proportions of red and blue LED light and found that blue light supplementation increased the plants' leaf area up to 20%. She noted that dill grown under 30% blue had "the greatest photosynthesis intensity" (Frąszczak, 2016).…”

Determining aroma differences among basil, parsley, and dill grown under varied supplemental light wavelengths using consumer sensory and flash gas chromatograph-electronic nose analyses

Greenhouse herb producers may use artificial lighting to supplement the natural light available to their crops. High-pressure sodium (HPS) lights are the most common supplemental lighting systems employed in such operations, but light-emitting diode (LED) lighting is increasing in popularity because of its energy efficiency, customizability, and environmental friendliness. LED lights can be customized to emit specific proportions of light wavelengths, but many herb producers do not know how these "light recipes" affect their crops, specifically their crops' aroma. This research utilized consumer sensory difference panels and flash gas chromatograph-electronic nose (GC-EN) analysis to evaluate the aroma of fresh basil, parsley, and dill herbs after cultivation under one of three supplemental light treatments: HPS, LED with a high proportion of blue to red diodes (high blue LED), or LED with a low proportion of blue to red diodes (low blue LED). Consumer sensory panels using triangle difference tests found that consumers could not determine the difference between herbs grown under HPS and high blue LED. Preliminary work suggests a similar result for HPS and low blue LED, but further research is required to confirm this. GC-EN analysis revealed no significant chemical differences between lighting treatments among basil or parsley. Subtle chemical differences were uncovered in dill GC-EN data, especially when nonpolar and mid-polar column data were examined separately to prevent false correlation from multiple detections of a single compound. Consistent with literature findings, linear discriminant analysis of these data subsets revealed that multiple volatile compounds in dill are affected by the supplemental lighting wavelengths available to the herb. viii In the scope of this study, there appears to be no overall aroma difference between herbs grown under HPS light and those grown under LED light, but more research must be conducted to confirm and expand upon these findings. Future research including sensory preference tests, descriptive analyses, GC-olfactometry, and GC-MS studies will make research like this more practical for herb farmers. CHAPTER 2: LITERATURE REVIEW Conventional Herb Cultivation Herb cultivation is extremely varied; small farms and large-scale producers alike operate in the U.S. (Rogers, 2012). Herbs and other essential oil crops like lavender and lemongrass are widely grown outdoors in warm climates (Adam, 2005). For example, much of the country's fresh basil comes from California, Hawaii, Florida, or abroad (U.S. Department of Agriculture, 2016). Because of wide global commerce, herbs grown in greenhouses abroad could supply the entire U.S. herb market (Adam, 2005). But should it? Promoting the local production of herbs would supplement local farming economies and provide fresher, higher quality herbs to consumers. In the U.S., herbs are often grown as "a way to stabilize small farm ventures" (Miller, 1985). The same is true in greenhouse systems: growing herbs is an easy way to supplement ...

In smart greenhouse farming, the impact of light qualities on plant growth and development is crucial but lacks systematic identification of optimal combinations. This study addresses this gap by analysing various light properties’ effects (photoperiod, intensity, ratio, light-dark order) on Arabidopsis thaliana growth using days-to-flower (DTF) and hypocotyl length as proxies to measure plant growth and development. After establishing suitable ranges through comprehensive literature review, these properties were varied within those ranges. Compared to white light, a 16-hour cycle of blue light reduces DTF and hypocotyl length by 12% and 3%, respectively. Interestingly, similar results can be achieved using a shorter photoperiod of 14-hour light (composed of 8 hours of a mixture of 66.7 µmol/m2s−1 red and 800 µmol/m2s−1 blue lights (i.e., blue: red ratio of 12:1) followed by 6 hours of monochromatic red light and 10-hour dark. These findings offer potential for eﬀicient growth light recipes in smart greenhouse farming, optimising productivity while minimising energy consumption.
