The days have been getting shorter for more than four
months and those shortening days triggered changes in tree leaves throughout
the northeast. As the days became shorter the production of chlorophyll, the
green pigment in leaves that produces sugars, declined and finally ended. The
chlorophyll broke down revealing the anthocyanins (red pigments) and the carotenoids
(yellow and orange pigments) that had been hidden all summer. As this is occurring an abscission layer of corky material forms at the base of the leaves’
petioles, cutting off the flow of water to the leaves, and weakening the leaves’
connection to the twig – which resulted in most of them falling to earth in the last few weeks.
The entire process resulted in an influx of “leaf
peepers” by car and tour bus, all looking to enjoy the brilliant autumnal
colors that decorated our hillsides. Even we locals took pleasure in the
colorful display, although we may not have enjoyed the increase in traffic on
normally quiet rural roads.
The display is almost over now, but photographs remain to remind us of the pleasures of autumn.
‘nough said, enjoy the show –
