Autumn Colour Around Christ Church

Written by John James, posted on Thursday, October 20, 2022

Despite (or maybe it’s because of) the hot, dry weather experienced this summer, the autumn colours currently being seen around the college are quite spectacular.

Plant leaves tend to change colour as daylength decreases and temperatures start to drop, the green food making chlorophyll in the leaves stops being made by the plant, revealing the other chemicals such as yellow flavonoids, orange carotenoids and red anthocyanins. These chemicals which are normally masked by the green chlorophyll are responsible for things like UV filtration, nitrogen fixation, and floral pigmentation. But autumn isn’t all about leaf colours, there are plenty of fruit and flowers around too.
