“…A large number of crops have been studied and grown under the availability and absence or a combination of both red and blue light at different wavelengths [94,95]. An increase in photosynthetic rate was reported in wheat [96], spinach [67], lettuce [97], cucumber [21], Chinese cabbage [49,98] and chrysanthemum [99] under a combination of red and blue LEDs, with the proportion of red LEDs being 80-90%. Nevertheless, photosynthetic rate was also observed to be increased under high photosynthetic photon flux density (PPFD) of green LEDs in lettuce [69].…”

“…Chlorophyll is produced by the reduction of its precursor "protochlorophyllide" only in the occurrence of light [125], whereas anthocyanin biosynthesis is due to the upstream light-dependent stimulation of "chalcone synthase" gene expression [126]. Many related studies have been conducted where different combinations of red and blue LEDs resulted in elevated chlorophyll contents in Chinese cabbage [98], capsicum [62], strawberry [60] and broccoli [127] seedlings. Chlorophyll content was found to be highest under pure red LED treatments in kale [57] and strawberry [60].…”

A reduction in crop productivity in cultivable land and challenging environmental factors have directed advancement in indoor cultivation systems, such that the yield parameters are higher in outdoor cultivation systems. In wake of this situation, light emitting diode (LED) lighting has proved to be promising in the field of agricultural lighting. Properties such as energy efficiency, long lifetime, photon flux efficacy and flexibility in application make LEDs better suited for future agricultural lighting systems over traditional lighting systems. Different LED spectrums have varied effects on the morphogenesis and photosynthetic responses in plants. LEDs have a profound effect on plant growth and development and also control key physiological processes such as phototropism, the immigration of chloroplasts, day/night period control and the opening/closing of stomata. Moreover, the synthesis of bioactive compounds and antioxidants on exposure to LED spectrum also provides information on the possible regulation of antioxidative defense genes to protect the cells from oxidative damage. Similarly, LEDs are also seen to escalate the nutrient metabolism in plants and flower initiation, thus improving the quality of the crops as well. However, the complete management of the irradiance and wavelength is the key to maximize the economic efficacy of crop production, quality, and the nutrition potential of plants grown in controlled environments. This review aims to summarize the various advancements made in the area of LED technology in agriculture, focusing on key processes such as morphological changes, photosynthetic activity, nutrient metabolism, antioxidant capacity and flowering in plants. Emphasis is also made on the variation in activities of different LED spectra between different plant species. In addition, research gaps and future perspectives are also discussed of this emerging multidisciplinary field of research and its development.

Definition of the growth and development characteristics of plants in varied light conditions is a key factor for the creation of highly efficient light facilities for plant cultivation. Experimental research was conducted using an LED irradiation facility with photosynthetic photon flux densities ranging from 0 to 261 μmol m−2 s−1 and a continuous spectrum with maxima at 445 and 600 nm. Under the maximum photosynthetic photon flux density (261 μmol m− 2 s−1) wheat germs demonstrated diminishing leaf surface with high values of specific leaf area, enhanced pubescence of ground tissues, increases in the number of stomata on the upper epidermis and palisade, and an increase in the thickness of the leaves as well as an increase in carotenoids but a decrease in the chlorophyll a+b/carotenoids relation. It was revealed that the optimum level of photosynthetic photon flux density for the referred spectrum was in the range from 82 to 100 µmol m−2 s−1, which may enable a reduction of irradiance under specific conditions during early development with no harm to the plants while minimizing energy consumption during cultivation.
