Abstract/Contents:"Heavy metal pollutants are present in agricultural soil in Taiwan due to use [of] heavy pesticides. There are many reports mentioned that many plants capable of absorbing contaminates [contaminants] from polluted soil via root. Pollutants are subsequently removed by harvesting aboveground plant tissues. Some plants used for phytoremediation including alfalfa, Arabidopsis, Bladder campion, Brassica juncea, Compositae family, Euphorbiaceae, and some grass family. In these, we think the turfgrass cultivars have the most valuable potential and the most effective in enhancing heavy-metal elements accumulation in plants. Because of the regular mowing of the turfgrass, we can use mulching mower to collect the clippings and remove for treatment. Among the turfgrass species, Seashore paspalum (Paspalum vaginatum) has the highest salt-tolerance of any turfgrass. The first stage of this study is going to observe the prescence of seashore paspalum for its phytoremediation to heavy-metal elements from contaminated soil in Taiwan. Our initial test was to screen the responses of seashore paspalum after exposed to heavy salt treatment and heavy-metal element. The comparisons of chlorophyll content measured by Chlorophyll meter (Minolta SPAD 502) of Zoysiagrass (Zoysia japanica), St. Augustinegrass (Stenotaphrom secundatum (Walt.) Kuntze), and Seashore paspalum were treated with artificial seawater every week in the greenhouse. Three treatments, including 0.1 mM., 1.0 mM of CsCl, and deionized water as control were using in non-radioactive heavy-metal absorption experiment for 4 weeks. The digested samples were analyzed for Cs by ICP-AES (Fisons Accuris, Fisons Instruments, Inc., Beverly, MA) and for K by flame photometer. The experimental design was a randomized complete block with five replications and was repeated at least once. After 7 weeks of treatment Seashore paspalum showed that the growth conditions were as well as control, but not Zoysiagrass and St. Augustinegrass. From the comparisons of chlorophyll content we found that Seashore paspalum was not affected by CsCl treatments, and was not affected by K content in leaves."
