Blue light is essential during a plant’s germination phase. colors of light to stimulate plant growth. This allows the plant to produce a greater yield. Plants require sunlight to grow, which they transform into usable energy in their chlorophyll. Plants will always grow its best when in ideal, natural conditions, not only when it comes to light but also water, warmth, and pH level of the soil. Without light a plant cannot grow, reproduce, or photosynthesize. According to the University of Missouri Extension, plants typically fall within one of three lighting categories—low, medium and high. You will calculate the plant growth by measuring the height of each plant under different colors of light. Aside from photosynthesis, however, some light colors help regulate other plant growth processes. As a result, different plant types may require different light intensities.

It also controls a plant’s cellular respiration and lessens water loss through evaporation during hot and dry conditions. These researchers grew microgreens under blue, red, and far red light to see if it would change the quantity of important antioxidants like phenols and anthocyanins, which give plants their red color, and beta-carotene, which gives plants their yellow and orange shades. All rights reserved. I think that colored light will have a huge affect on plant growth according to my research, all plants need light to grow and live. The receptor is a blue-green pigment called a phytochrome present in the cells of a plant. Different wavelengths of light can trigger or inhibit growth and flowering in plants. Want bigger, healthier, higher yielding plants? Many plants grown under only red light, such as plants grown indoors under only red LEDs, have a stretched, elongated appearance; the leaves are thin and large and plants become tall.

If the light shining over a plant has a shorter wavelength, the plant will grow faster than a plant under a light with a longer wavelength because it is under a light with more energy. 50 1 foot long pieces of 1x1 wood The plant does not absorb the green light so does not use it to grow. It is true that blue and red are important and represent most of the light used by plants, but other colors, including green and yellow are also used for photosynthesis. Different colors of light affect plants in different ways. But first, here is a quick summary, with extended information following: Ultraviolet - No exposure produces better growth, Violet - Enhances the color, taste, and aroma of plants, Blue - Increases the growth rate of plants, Green - Enhances chlorophyll production and is used as a pigment for proper plant viewing, Yellow - Plants exhibit less growth compared to blue and red light, Red - When combined with blue light it yields more leaves and crops, depending on what is being grown, Far Red - Speeds up the Phytochrome conversion which reduces the time a plant takes to go into a night-time state. These properties include, but are not limited to, height, weight, color, and texture, as well as the chemical composure of the plant itself. Compared to other light colors, the light intensity will be high enough to saturate the cells in a larger volume fraction of the reactor. Abstract The goal of this study is to learn how the colour of light affects photosynthesis, to identify the effects of different coloured lights on plant growth, and to identify the potential use of different light colours as a growth regulator. The project will explore what would happen if you gave a plant light, but in a different color. Light supplies the power to carry on photosynthesis, the food-making process in leaves.

This experiment attempts to discover whether the chlorophyll in plants can transform light into energy when certain colors of light are missing from the spectrum. Regular Light = high pressure sodium lamp, Red wavelength = 665nm. A color spectrum of the light absorbed by the whole leaf shows that plants actually use a wider range of wavelengths, including green. But the spectrum of light most utilized by a leaf is limited to three distinct colors, red, blue and yellow. As a plant grows, you can use LED grow lights to manipulate these physical properties depending on the plant characteristics that you desire. The plant needs to be watered, the soil needs to have certain nutrients, and it needs to be in an environment where it receives light for a certain amount of time. Think about plant growth and the elements that a plant needs to grow heartily. Blue light, for example, helps encourage vegetative leaf growth. Multiple studies have shown that exposing a plant to this color influences the formation of chlorophyll, which enables the plant to intake more energy from the sun. ", © 2021 Grobo.
