Possible effects of metals on the growth of gracilaria sp. (rhodophyta)

The effects of copper, zinc, and iron on the growth of Graci/aria sp. were studied in vitro. The Graci/aria sp. tissues were cultured under five different concentrations (OIlM, 0.1 J.1M, 0.5J.1M, 10.0J.1M and 50.0pM) of these metals. The growth rate and chlorophyll a concentration of the algae were...
