The response of C4, C3 and CAM species to naturally induced drought and their subsequent recovery are similar. However, there are differences in the degree of the pigment responses, which are related to the differences in the pigment composition of the species. During drought the decrease of the lutein, neoxanthin and chl b content indicates the reduction of the LHC-xanthophyll-proteins, while the considerably increased level of β-carotene, together with the elevated chl a/b ratio, reflect the increased amounts of chl a/β-carotene-pigment-proteins. Moreover, from the pigment data it is concluded that the species seem to possess during drought a higher proportion of pigment-proteins of PSI than pigment-proteins of PS II. These reactions to drought decrease gradually in the direction of C4-C3-CAM (succulence). The C4Festuca vaginata responds with a considerable change in its pigment composition, while this is moderate in CAM Sedum, and C3Achillea occupies an intermediate position.
