“…LED is an ideal tool to study light quality requirements of every horticultural crop. Th eir small size, durability, long operating lifetime, wavelength specifi city, relatively cool emitting surfaces, and linear photon output with electrical input current make these solid-state light sources ideal for use in plant lighting designs (Massa et al 2008;Liu 2012).…”

Eff ect of the end-of-day and the end-of-night red and blue light in dill growth was investigated. Ambrozja dill (Anethum graveolens L.) cvs were grown in vegetation chambers in completely controlled conditions exposed to white diode light. Red and blue light was employed for 30 min before the initiation or after the end of the lighting period. Th e values of plant fresh mass, area and height parameters were the highest for plants treated with red light at the end of night. Th e application of red light at the end of day exerted a similar eff ect on plants as the exposure of plants to blue light at the end of night. Plants treated with blue light at the end of the lighting period were characterised by the poorest growth rate. Plants additionally lighted with blue light were found to have both distinctly smaller mass as well as area in comparison with plants exposed to red light. Both methods are useful to control the plants growth depending on the phase of plant development and growers' requirements.

“…Ánh sáng là yếu tố quan trọng trong quá trình sinh trưởng và phát triển của thực vật. Thực vật không chỉ phản ứng với cường độ ánh sáng mà còn phụ thuộc vào chất lượng và màu sắc của ánh sáng thông qua các quang thụ thể hoạt động dưới các vùng quang phổ đặc trưng (Zhang, Folta, 2012;Liu, 2012). Sự sinh trưởng và phát triển của thực vật có thể được thúc đẩy bằng cách gia tăng tốc độ quang hợp dưới vùng quang phổ là đỉnh hấp thu của các sắc tố quang hợp, vùng quang phổ này thường là giao thoa giữa hai loại LED xanh (450 nm) và LED đỏ (660 nm).…”

In this study, the influence of different LED lighting intensities, different lighting periods of red LED and blue LED on growth, development and chlorophyll a and b synthesis on in vitro Chrysanthemum were presented. Shoot tips were inoculated and were put under 70% red LED: 30% blue LED lighting condition with different LED lighting intensities: 30, 45 and 60 µmol.m-2.s-1; different LED lighting periods: weekly intermittent lighting with red LED/blue LED (blue LED or red LED lighting for the first week), intermittent lighting with red LED/blue LED for each two weeks (blue LED or red LED lighting for the first two weeks). After 6 weeks of cultured, the results showed that LED lighting source with intensity 60 µmol.m-2.s-1 had the best stimulation on growth and development of Chrysanthemum; however, under intensity 45 µmol.m-2.s-1, chlorophyll a and b content still were the highest. In addition, weekly intermittent lighting with red LED and blue LED (blue LED was lighted at the first week) gave the best results on growth and development of Chrysanthemum. Thus, the most suitable LED lighting intensity for growth and development of in vitro Chrysanthemum was 60 µmol.m-2.s-1, and weekly intermittent lighting with red LED and blue LED (blue LED was lighted at the first week) will promote the growth and development of in vitro Chrysanthemum. The survival rates, growth and development of plants under 70% red LED: 30% blue LED and 50% red LED: 50% blue LED were higher than those of plants under Florescent, after 4 weeks of cultured in the greenhouse.

“…The blue and red light are essential vital spectral bands for plants; violet, green, yellow, and orange lights confer minor benefits; and UV and far red light confer major benefits to plants (Liu, 2012). The quality of light decisively affects production of secondary metabolites in plants (Victório et al, 2015).…”

“…However, green light produced the lowest concentrations of the evaluated phytochemicals, with less beneficial effects (Liu, 2012). Johkan et al (2012) evaluated the growth of lettuce under green light and found that at high light intensity, green light can stimulate the phenylpropanoid pathway.…”

Anacardium othonianum Rizz., popularly known as the Cerrado cashew tree, is widely used in medicine due to its therapeutic properties, including its antioxidant, anti-inflammatory, and antidiarrheal activities. Light is an important regulator of the growth, development of plants differentiation, and metabolism. Considering the influence of light on the production of phytochemicals, the aim of the present study was to evaluate production of gallic and 3,4-dihydroxybenzoic acids and amentoflavone in A. othonianum seedlings grown in vitro exposure to white, blue, green, red, and yellow light. The seedlings were evaluated with respect to the length of the aerial parts and the number of leaves, at 0, 20, and 40 days of treatment. The fresh and dry weights of the aerial parts and the levels of phenolic acid and biflavonoid were evaluated at 40 days via high-performance liquid chromatography with a diode array detector (HPLC-DAD). Regardless of the light wavelength used for the growth, the largest length of the aerial parts (5.54 cm) and an increase in the number of leaves (2.86-fold) were observed at 40 days. The largest accumulations of fresh weight (325.5 mg and 335.1 mg per seedling) and dry weight (83.3 mg and 84.5 mg per seedling) were observed in seedlings grown under red and yellow light, respectively. Relatively higher levels of gallic acid (0.66 mg.g -1 dry weight) and amentoflavone (1.41 mg.g -1 dry weight) were found in seedlings grown under blue light. In contrast, the 3,4-dihydroxybenzoic acid levels of the seedlings under red light increased (8.22 mg.g -1 dry weight).
