Fundamentals and Applications of Red Light-Emitting Diodes (LEDs) In Vitro Plant Growth on Tomato Lycopersicon esculentum Mill

Abstract:

The aim of these studies was mainly to investigate the effects of monochromatic LEDs applied singly on the in vitro plant growth and morphogenesis. Various morphological and physiological parameters are considered that influence the growth and development of plants in vitro under red LED light as compared to those under normal light. Upon exposure to LED, in vitro-raised plants have shown significant improvements in growth and morphogenesis. In particular, red and blue lights, either alone or in combination, have a significant influence on plant growth. The present study gives an overview of the fundamentals of LEDs and describes their effects on in vitro plant growth and morphogenesis and their future potentials. The main objective of this study was to carry out line and combing ability of plant growth on tomato.

[8] Previous studies showed that leaf thickness of several plant species decreased when plants were grown under low broad-spectrum [15] or blue light levels [16]. Conclusion Red LED light is effective for root growth. Blue and red LED may be used as an alternative light source for upland cotton culture systems. This is the first report on measuring the effects of LED light on upland cotton in vitro, to determine what types are important for upland cotton growth. Using LED-based light sources, it is possible to regulate and control the physiological aspects of plant growth, such as photosynthesis and/or photo-morphogenesis. A continuous acquisition of new concepts and knowledge in the photobiology and morphogenesis, complemented with the rapid development of LED technology, may make the application of solid state lighting more remunerative in in vitro plant propagation Acknowledgement This research is funded by Ho Chi Minh City University of Technology-VNU-HCM under grant number T-KHUD-2018-23.
