Hi Folks,
Part of my class today will concern fall colors. I always learned that these
pigments were already present but masked by chlorophyll. Upon degradation of
chlorophyll these pigments can be seen. I recently read a report in the
local newspaper that the red pigments (anthocyanins?) are actually
synthesized in the fall and the brown pigments (in oaks) are waste products.
Does anybody know what the latest info is on this timely topic?
