Book Description
Excerpt from The Influence of Light and Darkness Upon Growth and Development The results described in the following pages were obtained by a series of experimental observations begun in 1895 and continued until the close of the year 1902. Originally designed to analyze the phenomena of etiolation, the work has naturally led to a consider ation of the more general relations of the plant to light, and it is believed that some important additions to the knowledge Of the sub ject have been made. The chief results of value have been obtained by long continued confinement Of the etiolating plants in dark cham bers from which light was entirely excluded.

Book Description
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.
