In this study, photosynthetic performance, pigment content, chlorophyll a fluorescence, and leaf anatomy in Arachis hypogaea subjected to Zn stress were investigated. Zn stress resulted in reduction of photosynthetic and transpiration rates, pigment contents and root biomass. Zn-induced xerophyte structure in peanut leaves (i.e. thick lamina, upper epidermis, and palisade mesophyll, as well as abundant and small stomata) also contributed to decreased transpiration rate and stomatal conductance. This in turn, partially contributed to the limitation of photosynthesis.
