The Science behind the Colors of Fall

Laura's picture

Autumn is here and the leaves on the trees in Central Ohio are beginning to change color and fall to the ground. It is a ritual we look forward to, but take for granted, every year.

But just what mystery causes this yearly display that we enjoy so much?  We know that shorter days, and cooler nights stop a tree from producing the green pigment in leaves.  The fall colors of red, yellow and orange remain.  Recent research has shown that the type of soil a tree is growing in also has an effect. 

Scientists at Princeton University are studying the effect of long-term climate trends on leaves.According to researchers,  leaves will start changing color later than usual, and the vivid colors of fall will last longer than usual in coming years. 

These and other articles explaining what makes leaves change color, what factors produce the most vivid fall colors and what makes leaves of deciduous trees drop off each year at this time may be found in the library’s science databases.  Take a look at the science and then go outside and enjoy the splendid display.
