“…As an important ecological factor, light affects the photosynthesis of plants, also has a bearing on the chemical composition of plants (Fukuda, 2019;Kyriacou et al, 2016;Rouphael et al, 2018). Despite previous studies on the effects of light quality and light intensity on crop growth and quality (Fiutak et al, 2019;Frede, Schreiner & Baldermann, 2019;Kaiser et al, 2019;Ruangrak & Khummueng, 2019;Shibuya et al, 2019), few studies have involved under-forest economic crops such as wild vegetables. MS, AM, OCA and PAL are important wild vegetables in Northeast China (Liu & Li, 1995;Liu & Wang, 2018), but there was little research on the effects of light conditions on the quality of such four edible fern species.…”

Total phenols, flavonoids, minerals and amino acids content were investigated in leaves of four fern species grown under four shading treatments with different sunlight transmittance in 35% full sunlight (FS), 13% FS, 8% FS and 4% FS. The leaves of four fern species contain high levels of total phenols and flavonoids, abundant minerals and amino acids, and these all were strongly affected by transmittance. Total phenols and flavonoids content were significantly positively correlated with transmittance, while minerals and total amino acids content were significantly negatively correlated with transmittance, a finding that supports research into how higher light intensity can stimulate the synthesis of phenols and flavonoids, and proper shading can stimulate the accumulation of minerals and amino acids. Matteuccia struthiopteris (L.) Todaro (MS) had the highest total phenols content, Athyrium multidentatum (Doll.) Ching (AM) showed the highest total amino acids, total essential amino acids content, Osmunda cinnamomea (L) var. asiatica Fernald (OCA) exhibited the highest total non-essential amino acids and flavonoids content. Pteridium aquilinum (L.) Kuhn var. latiusculum (Desy.) Underw. ex Heller (PAL) exhibited the highest minerals content. This research can provide a scientific basis for the cultivation and management of those four fern species.

“…However, in our study 20% G did not induce much effects, which is comparable to the study of Hernández and Kubota (2015) who analyzed the effect of 28% G in cucumber. Kaiser et al (2019) found that replacing 32% of a red/blue mixture spectrum by green light signi cantly increased plant biomass and yield. These different observations among studies suggest that G effects might be genotype-speci c and dependent on and/or interact with other environmental conditions.…”

Although green light is often neglected it can have several effects on plant growth and development. Green light is probably sensed by cryptochromes (crys), one of the blue light photoreceptor families. The aim of this study is to investigate the possible interaction between green and blue light and the involvement of crys in the green light response of plant photomorphogenesis. We hypothesize that green light effects on morphology only occur when crys are activated by the presence of blue light. Wild-type Moneymaker (MM), cry1a mutant (cry1a) and two CRY2 overexpressing transgenic lines (CRY2-OX3 and CRY2-OX8) of tomato (Solanum lycopersicum) were grown in a climate chamber without or with green light (30 µmol m− 2 s− 1) on backgrounds of sole red, sole blue and red/blue mixture, with all treatments having the same photosynthetic photon flux density of 150 µmol m− 2 s− 1. Green light showed no significant effect on biomass accumulation, nor on leaf photosynthesis and leaf characteristics such as leaf area, specific leaf area, and chlorophyll content. However, in all genotypes, green light significantly decreased stem length on a sole blue background, whereas green light did not affect stem length on sole red and red/blue mixture background. MM, cry1a and CRY2-OX3/8 plants all exhibited similar responses of stem elongation to green light, indicating that cry1a, and probably cry2, is not involved in this green light effect. We conclude that partially replacing blue light by green light reduces elongation and that this is independent of cry1a.

“…Arabidopsis thaliana seedlings grown under a combination of G, R, and B lights were taller than those grown under monochromatic R or B lights [12]. In addition, as the proportion of G light increased in the combination of B, R, and G light, fresh weight and dry weight of tomato plants and fruit increased [13]. It is reported that UV-B inhibited stem elongation…”

This study aimed to determine the effects of various light qualities (green (G), ultraviolet-A (UV-A), and far-red (Fr)) on the growth and development of tomato plug seedlings. The ‘Mini Chal’ tomato (Solanum lycopersicum L.) seedlings were used as the plant material to which various light qualities were supplied. Fluorescent lamp (FL), combined FL and diniconazole (Dini), and R3B7 (red (R):blue (B) = 30:70) were used as the control. The different light treatments for this experiment were as follows: two G light ratios added to R3B7 (G20 and G40), three UV-A light intensities added to R3B7 (UV 0.4, UV 0.6, and UV 0.8), and three Fr light ratios added to R3B7 (Fr1, Fr2, and Fr3). Plants grown in UV 0.4 and Dini were the shortest, followed by plants grown in R3B7. R3B7 induced higher specific leaf weight than G, UV-A, and Fr did. The position of the first flower cluster was the highest for plants in FL and Fr1, and the lowest for plants in R3B7 and UV 0.6. In conclusion, different light treatments heavily affected the growth and development of ‘Mini Chal’ tomato seedlings. R3B7 was the most effective light treatment for producing high quality seedlings in a closed-type plant production system that develop well after transplanting.
