Resumen: The research on species with capacity to tolerate and accumulate zinc is of paramount importance for phytoremediation purposes. An experiment was designed to investigate the effect of Zn from 0 to 100mmoll-1 on the growth, photosynthetic apparatus and nutrient uptake of the halophytic species Juncus acutus. Gas exchange, chlorophyll fluorescence and photosynthetic pigments concentration were measured. We also determined total zinc, magnesium, potassium, phosphorus and sodium concentrations, as well as C/N ratio. J. acutus showed high tolerance to Zn-induced stress, since all plants survived and none of them showed any toxicity symptoms, such as chlorosis, necrosis or growth reduction at concentrations up to 100mmoll-1 Zn. The integrity and functionality of the photosynthetic apparatus were unaffected even at zinc concentrations greater than 500mgkg-1 on tillers. Likewise, nutrient absorption was relatively unaffected. Zn tolerance was associated with the capacity to accumulate Zn in r...
