Abstract
Light is the major source of energy for plants and as such has a profound effect on plant growth and development. Red and blue lights have been
considered to best drive photosynthetic metabolism and are beneficial for plant
growth and development, and green light was seen as a signal to slow down or
stop. In this study,
Arabidopsis thaliana (
Arabidopsis) was used to investigate
the effects of red, blue and green lights on the growth and development of plants
from seed germination to seeding. Results demonstrated that red light showed a
promotion effect but blue light a prohibition one in most stages except for the
flowering time in which the effect of each light was just reversed. When mixed
with red or blue light, green light generally at least partially cancelled out the
effects caused by each of them. Results also showed that the same number of
photons the plant received could cause different effects and choosing the right
combination of different color of lights is essential in both promoting the growth
and development of plants and reducing the energy consumption of lighting in
plant factory.
