Abstract
Zea mays and Spartina patens were grown in nutrient solution containing either an oxidized (+4) or a reduced (+3) form of titanium citrate. Low oxidation-reduction conditions in the nutrient solution as a result of titanium (+3) citrate reduced photosynthetic activity of Zea mays. Photosynthetic activity of flood-tolerant S. patens was initially reduced by the addition of titanium (+3) citrate but subsequently increased, indicating the existence of adaptation mechanisms in S. patens. Titanium citrate was non-toxic since titanium (+4) citrate (oxidized form) added to rooting medium resulted in no reduction in photosynthetic activity of either species. Titanium (+3) citrate may be an excellent non-toxic oxidation-reduction buffering system for evaluating wetland plant response to root oxygen stress. © 1990.
