Plants are dependent on light to generate food, induce the growing cycle and allow for healthy development. Copyright 2020 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. After attending Hardin Simmons University, Kay Dean finished her formal education with the Institute of Children's Literature. It is a complex subject and in this paper the effects of different light conditions are discussed. Artificial Light. when to bud, flower, germinate, etc.) Artificial lights allow for year-round growth and quick production, but the intensity and nutrients that natural sunlight offers can never truly be duplicated. This process is called photomorphogenesis. By limiting the amount of light and the number of hours exposed, you can induce the flowering stage artificially. This waveband is within the visible spectrum, has relatively high energy, and has pronounced effects on plant growth and flowering. Artificial light will work almost as well--fluorescent, incandescent, LED or high-intensity discharge lamps (like metal halide or high pressure sodium). Plants should receive 16 to 18 hours of artificial light each day. By the appropriate use of artificial light greater control over the growth and development of plants is possible. Importance of Light for Plants. Sunlight is the best light for plants. Professor Kevin Folta of the University of Florida has produced experiments in which plants' development, especially as seedlings, is actually harmed by green light. Artificial light allows plants to be grown anywhere in a home; however, not every light bulb will suffice. Red light can be used to induce flowering and lengthen the internodes to produce plants with longer stems and bigger flowers. But it’s a good option to consider if you want to grow some vegetables like lettuce or fruit like tomatoes indoors. The "cool white" fluorescent tubes, as well as special plant fluorescent lights are selected by many indoor gardeners, according to the University of Missouri. This process creates a sugar called glucose and also produces oxygen. Fluorescent light tubes are a good source for providing light for plants; however, there are a variety of fluorescent tubes. Whether you opt for the traditional long tubes or more modern compact fluorescent light bulbs (CFL),... Incandescent Bulbs. Too much fluorescent light will also harm plants -- artificial light should mimic the day and night cycles found in nature. But it’s a good option to consider if you want to grow some vegetables like lettuce or fruit like tomatoes indoors. Blue light also has an effect on photosynthesis, and more exposure to this light can increase a plant’s growth and maturity rates. Light gives food and energy to plants through photosynthesis and makes everything flourish. Indoor plants placed within 10 feet of a sunny window receive the natural balance of red and blue rays they need. The plant knows to start reproducing and begins its flowering stage, laying seed for another season and finally reaching dormancy. All plants need light to grow. The light energy (from the sun) then triggers a chemical reaction that breaks down the carbon dioxide and water molecules. Artificial Light How plant growth is affected by artificial light depends on the type of light that is being discussed. Different characteristics of light such as spectral composition (wavelengths), intensity, duration and direction can influence plant growth and development. "Burpee Complete Gardener"; Barbara Ellis, Editor; 1995. Light supplies the power to carry on photosynthesis, the food-making process in leaves. Plants can use the energy contained in artificial light for photosynthesis. But sunlight is best for most plants. Free and plentiful, sunlight gives plants exactly what they need. ASU Center for Bioenergy and Photosynthesis. Researchers can successfully grow plants using only artificial light in growth chambers. Then Mickens flash-froze some of the plants in liquid nitrogen and ground them to a powder in order to perform a new test, an adenosine triphosphate analysis, which measures stored energy in the plant tissue. In fact, artificial light can be extended to 24 hours to enhance total plant growth. Light directly influences plant growth and flowering by inducing photosynthesis and feeding plants energy. LED grow lights on the other hand are specifically designed for the benefit of plants and … Artificial light can provide the energy necessary for their growth. The Effect of Light on Tomato Plant Growth. The most popular artificial light sources are LED Grow lights, HPS, and CFL lamps.
