Autumn Classic

Trees along the Kansas River show off their fall colors in preparation for a long winter.

Think the trees around Eudora are particularly beautiful this time of year? Thank photoperiodism. Photoperiodism, the method that allows trees to adjust to changes in available daylight, induces senescence. Senescence, a collection of processes that lead to the aging of the tree`s leaves, decreases the ability to produce chlorophyll.

A decreased amount of chlorophyll lets yellow and orange carotinoids and xanthophylls show through, producing fall colors.

Had enough? But, it`s easy enough to enjoy fall without the science. And it`s more than just pretty colors. True beauty is found in people helping their neighbors on a cool autumn evening. True fall beauty is the sight of children playing in crackling soft piles of leaves and remembering what it was like years ago. Back when you had the energy and time to take flying leaps.

Thankfully, fall enjoyment extends beyond the boundaries of age and time as much as it extends beyond scientific boundaries. However, time is limited before the anthocyanins, or red colors, disappear. Take time to savor fall before the winter sets in.
