Laser biostimulation in seeds and plants

Abstract

Different lasers have proven to be potentially useful to certain parameters of radiation and could benefit the establishment of planting in adverse conditions by UV-B radiation, drought, cold, salinity, pollution by cadmium, etc. This literature review shows the possible applications of lasers in recent years, as seed treatment and plants, emphasizing the use of He-Ne lasers, Ar, neodymium-YAG, CO2 and laser diodes. It is clear that applications of lasers to parameters specific irradiation of seeds and plants have become increasingly important because of the need to increase food production globally by methods that protect the environment and help to combat the effects of climate change and biodiversity conservation, improving the quality of human and animal life. Thus, in the International Year of “Light and light-based technologies,” it was important to become aware of possible potential use of laser light in agriculture because it could contribute to sustainable development and offering solutions to problems diverse. Advances that have found various scientists in the world provide evidence, thus, in the coming years could have a boom in its application in agriculture as an element “biostimulator” of seeds, seedlings and plants.
