November Leaves 2010

The deciduous leaves did not start turning colors until November.
In mid - November we are seeing the colors at their peak.
Isn't there a song about September leaves?
Well someone should write one about November leaves.

The pictures below were taken in the back yard.

The next pictures were taken from
the car while driving home from Petsmart.

Parking lot at work.

When fall arrives and the days are shorter or when plants are drought stressed, deciduous trees
decrease chlorophyll pigment production allowing other pigments present in the leaf to become
apparent, resulting in non-green colored foliage.

The brightest leaf colors are produced when days grow short and nights are cool but remain above freezing.
These other pigments include carotenoids that are yellow, brown, and orange.

Anthocyanin pigments produce reds and purple colors, though they are not always present in the leaves but are
produced in the foliage in late summer when sugars are trapped in the leaves after the process of abscission begins.

Parts of the world that have showy displays of bright autumn colors are limited to locations
where days become short and nights are cool.
