Seasonal behavior of chlorophyll in some shrubs grown under mesic and xeric habitat conditions

Abstract

At two distinctive habitats, the chlorophyll contents (Chls.), its thermostability (CSI), and some metabolic substances in four shrubs were studied. The obtained results revealed that, Chl. contents, Chl. a/b ratio and CSI were variables among the investigated species in response to seasonality, habitat, species and their
