Synopsis

Excerpt from Light and Plants: A Series of Experiments Demonstrating Light Effects on Seed Germination, Plant Growth, and Plant Development; January 1961

Vegetative growth of plants is to a large degree controlled by light. Plants grown in total darkness have very long internodes, small leaves, and are yellow in color because no chlorophyll is formed. If the dark grown plants are exposed to weak light for a minute or two each day, the plants have shorter internodes and normal-size leaves, although they may still be yellow and without visible chlorophyll. Daily exposures of the plants to light of higher intensities or for a longer duration may not change the size of the leaves or inter nodes of the plants from that obtained with brief exposures to light of low intensity, but the plants turn green as chlorophyll is formed.
