Welcome, midwestern plant enthusiasts! As the days grow shorter up north and temperatures start to drop, nature puts on a spectacular show, transforming the landscape into a vibrant canvas of vibrant hues. Ever wondered why leaves change color in the fall? Let’s unravel the mystery behind this enchanting phenomenon.
Chlorophyll’s Farewell
Say Goodbye to Green
As autumn approaches, trees begin their preparation for the winter months. The first act in this natural spectacle involves chlorophyll, the green pigment responsible for photosynthesis. With sunlight dwindling and temperatures declining, trees cease chlorophyll production. As a result, the vibrant green fades away, revealing the true colors hidden beneath.
The Palette of Pigments
Unveiling Nature’s Palette
As chlorophyll bids adieu, other pigments take center stage. Carotenoids, responsible for yellow and orange hues, become more prominent. These pigments are present in leaves throughout the year but are typically overshadowed by the dominant green chlorophyll. Carotenoids are synthesized by plants, algae, certain bacteria, archaea, and fungi. These pigments are responsible for the distinctive hues seen in trees, pumpkins, carrots, parsnips, corn, tomatoes, canaries, flamingos, salmon, lobster, shrimp, and daffodils.
Anthocyanin’s Grand Entrance
A Touch of Red
Some trees, however, have an extra trick up their sleeves. In addition to carotenoids, certain species produce anthocyanin, a pigment responsible for red and purple shades. Anthocyanins, belonging to the category of water-soluble flavonoids, are commonly found in a variety of fruits and vegetables. Dietary outlets for anthocyanins encompass red and purple berries, grapes, apples, plums, cabbage, and foods enriched with abundant natural colorants. This pigment is not present in leaves throughout the growing season. Instead, it forms in response to certain triggers like cool temperatures and sunny days, creating a stunning contrast to the yellows and oranges.
