How Light Effects Plant Development
October 16, 2018
Overall plant growth and development depends not only on the spectrum of light received, but also on the color combination, color sequence, and duration of each. Plants have evolved to employ finely tuned sensors to use different spectrums of light for different stages of growth and reproduction.

Plants use different spectrums of light to regulate developmental stages (such as germination, rooting, stem elongation, leaf unrolling, flowering, and dormant bud development), which is known as photomorphogenesis.
