Abstract
With increasing altitude, the concentrations of chlorophyll (chl), carotenoids and phenolics decreased but the chla :b ratio increased in the fourArtemisia species grown at four altitudes. The increase in chla : b ratio was due to a reduction in chlb content. The changes in anthocyanin content were irregular. Thus phenolics and anthocyanin pools may be differently regulated along an altitudinal gradient.
