Read the following article to reinforce concepts of fall color.
- Leaf Color Change in Autumn, University of Wisconsin-Madison Extension
- You’ll note that in this article, it mentions how the red anthocyanin pigments are produced in fall “to help shade leaf photosynthetic systems from bright sunlight”. This may strike you as different than what the video says. The presenter talks about how the specific research she did on maples did not find evidence to support this statement. It’s a good time to point out that there are lots of specifics in science. The presenter makes sure to note that while her research on senescing maples does not support the idea that anthocyanins provide either significant additional antioxidant or light screening benefits, there is evidence that this is true for other plant species.
