Tree of trees confirms complexity of colour conundrum


Figure 1
People will pay good money to travel in order to see dying leaves. Put like that it sounds crazy but actually the colours on display during the autumn in some parts of the world are spectacular. However, autumn colours are not an inevitable by-product of leaf senescence. It is not a universal feature that leaves produce brilliant colours; indeed it is not even the norm. In the northern hemisphere, the forests of New England, with a high proportion of Acer species, show us that it is particular types of tree, sometimes aided by weather conditions, that provide the autumn colours. We can distinguish two main types of colour producers. In predominantly yellow leaves, the loss of chlorophyll allows the accumulated carotenoid pigments to be seen. In predominantly . . .
