The Science of Leaf Color Change
You can view learning about the science behind the production of colors in autumn foliage as either removing the mystery behind a phenomenon, or making the phenomenon even more amazing (as we do). In order to learn about the science behind the phenomenon, we provide brief descriptions of the following. Together, they summarize what is known about this process.
Leaf Pigments
The pigments (chlorophylls, carotenoids and anthocyanins) which, in various combinations, account for the colors produced during autumn
Leaf Structure and Function
What is needed to understand about how leaves operate, to understand what the function of color during the autumn might be.
The Process of Leaf Color Change
What actually occurs in leaves during the autumn, to produce the color changes. Two examples, red oak and witch hazel, are highlighted.
The Biological Significance of Color Change
The scientific explanations, involving physiology as well as interactions with animals, that have been proposed to account for the brilliant colors of the autumn.
