Observing canopy characteristics during the growing season is a good way to understand the plant’s response to its environment. Occasionally, portions of the canopy may develop reddish-purple or red tones. The synthesis of anthocyanin, the pigment which typically causes the reddening, is commonly increased after leaves are exposed to light following multiple abiotic and biotic stresses.
