“…Some scholars have studied pea seedlings, lettuce seedlings and strawberries under illumination, and found that red light can increase leaf area of pea seedlings, inhibit internode elongation of plants, promote tillering and increase the accumulation of chlorophyll, carotenoids, soluble sugar and other substances (Chen et al, 2017;Li et al, 2017;Díaz-Galián et al, 2020). Blue light is an important influencing factor of photosynthetic system activity and photosynthetic electron transfer capacity of plants, which can obviously shorten the vegetable internode spacing, promote lateral extension and reduce leaf area, and at the same time, blue light can also promote the accumulation of secondary metabolites of plants (Hitz et al, 2020;Díaz-Rueda et al, 2021). There are obvious species differences in the demand for light quality of plants.…”

In recent years, plant factories have developed rapidly and played an important role in modern agricultural production. Finding the best lighting formula has become the most basic and important research topic for the industrialization of the plant factory with artificial lighting (PFAL) hydroponic Cichorium endivia L. In this paper, the LED plant growth lamp with adjustable ratio of red, blue and white light intensity was used as the light source for the growth of C. endivia L., with 5R:8B:7W, 6R:7B:7W, 5.5R:8B:6.5W as the treatment group and white LED as the control group, the growth characteristics and nutritional quality of the grown plants of C. endivia L. were compared and analyzed through experiments. It was found that under the combined illumination of 5.5R:8B:6.5W, the leaves of C. endivia L. had the largest number, and the contents of VC (Vitamin C) and carotene were the highest. Under 6R:7B:7W illumination, the content of chlorophyll and soluble sugar was the highest. The combination illumination with the ratio of blue and white light slightly larger than that of red light was the most suitable illumination for hydroponic cultivation of C. endivia L. in PFAL.

LED Lighting Effects on Plant Growth and Quality of Pyrus communis L. Propagated In Vitro

et al. 2022

Fluorescent lights are typically used as light source in indoor horticultural production, including micropropagation. However, light emitting diodes (LEDs) have been recently used for plant growth under controlled environment. Major advantage of LEDs is wavelength specificity, that allows to adequately adjust the spectra according to plant needs. The possibility of using LED as primary light source for the micropropagation of Pyrus communis L. has been investigated in this work. It was proceeded to the optimization of a protocol of micropropagation using a LED lamp as the primary light source inside of the growth chamber with specific wavelengths, to reduce energy consumption and increase the quality of the micro propagated plants. Explants were maintained in a growth chamber and exposed to three different continuous spectrum LED lamps (AP67, NS1, G2) as a primary light source and fluorescent lamps (control) for 4 weeks. At the end of four weeks period, it was proceeded to the morphometric and biochemical analysis. Shoot and leaf growths were more influenced by LED lamps as compared to fluorescent lamps (control) in both cultivars. The results showed that the shoots of William and San Giovanni cultivars showed significant differences in morphological and physiological traits, as well as in chlorophyll, carotenoid, and MDA contents. Highest number of neo-formed shoots and nodes were observed in the plantlets of cv William under AP67 LED followed by NS1 and G2 LED lights respectively as compared to the white light (control), whereas same trend was observed in cv San Giovanni under AP67 LED, but it showed higher shoots and node numbers under control LED lamps as compared to both NS1 and G2. The photosynthetic pigments were significantly decreased in leaves of both cultivars when grown under LEDs as compared to the control fluorescent lamps. Moreover, the AP67 LED light had also significant effects on the protein and MDA contents in the leaves of both cultivars in comparison to all other treatments. This work underlines the importance of the modulation of light sources in relation with different species and varieties, allowing optimizing the proliferation phase and the efficiency of Pyrus communis L. micropropagation protocol. Moreover, this protocol can be improved with further studies to examine the response of the plantlets to the ex-vitro acclimatization because the possibility of using LED light for the micropropagation of pear can be considered as a valuable alternative for its ecologically sustainable production.

This research focuses on the seasonal patterns of the ecophysiological recovery of four olive cultivars (Arbequina, Coratina, Frantoio, and Urano), both micropropagated and self-rooted, grown in a mature, irrigated, super high-density (SHD) orchard under Mediterranean conditions (Southern of Italy). The aim was to observe the impact of the micropropagation method on the ecophysiological responses. Ecophysiological parameters, including leaf water potential (LWP), stomatal conductance (gs), net photosynthetic rate (Pn), and transpiration rate (E) were assessed. Self-rooted trees consistently exhibited superior gs, E, and Pn recovery compared to the micropropagated ones. ‘Arbequina’ maintained elevated levels of Pn under water-deficit conditions. ‘Coratina’ exhibited increases in gs and E after irrigation. ‘Frantoio’ demonstrated recovery capabilities, with lower LWP and higher Pn under stress. ‘Urano’ micropropagated trees achieved higher gs values in mid-summer, while self-rooted trees sustained higher Pn later in the season. This field research highlighted the important role of the propagation method in optimizing the physiological performance of olive cultivars in SHD orchards. Furthermore, it highlighted the necessity of long-term studies on the effects of propagation methods and their interactions with other farming practices.
