It’d be like spending money to...I don’t know...to have your old car repainted when you know the car’s not going to last more than a couple of months.
All this extra anthocyanin in the autumn seems like a waste. But remember nature is very economical with its resources.
So that means anthocyanin must be serving some function that’s important for the tree.
Today, there are some theories about what that function might be. One of them involves predatory insects; another involves fungi.
You know, the more I read about these theories and the related research, it always created more questions for me than answers.
So I was really glad to learn about a totally different theory, a new one.
It seems to come with research and data that give a full explanation.
So here it is. Remember I said the chlorophyll breaks down? Well, in autumn, a whole lot of other chemical constituents of the leaf break down as well.
I don’t mean they are totally destroyed ‘cause actually they break down into other different chemicals that the tree can reabsorb from the leaves and reuse later.
