Research conducted in the Southern High Plains of Texas has shown that Lemna obscura grew well in cattle feedlot runoff water and produced leaf tissue with a high protein content. A model or mathematical expression derived from duckweed growth data was used to fit data from experiments conducted in a greenhouse in Lubbock, Texas. The relationship between duckweed growth and the total nitrogen concentration in the mediium follows the Mitscherlich Function and is similar to that of other plants. Empirically derived model equations have successfully predicted the growth response of Lemna obscura.

The rates of nitrogen and phosphorus uptake by the duckweed growing in the in vitro system were as high as 3.36 g m -2 day -1 and 0.20 g m -2 day -1 , respectively. The highest nitrogen and phosphorus removal rates in the field duckweed system were 2.11 g m -2 day -1 and 0.59 g m -2 day -1 , respectively. The highest observed duckweed growth rate was close to 29 g m -2 day -1 in both conditions.

Together with its naturally ability to thrive on abundant anthropogenic wastewater, these plants hold tremendous potential to helping solve critical water, climate and fuel issues facing our planet this century. With the conviction that rapid deployment and optimization of the duckweed platform for biomass production will depend on close integration between basic and applied research of these aquatic plants, the first International Conference on Duckweed Research and Applications (ICDRA) was organized and took place in Chengdu, China, from October 7th to 10th of 2011. Co-organized with Rutgers University of New Jersey (USA), this Conference attracted participants from Germany, Denmark, Japan, Australia, in addition to those from the US and China. The following are concise summaries of the various oral presentations and final discussions over the 2.5 day conference that serve to highlight current research interests and applied research that are paving the way for the imminent deployment of this novel aquatic crop. We believe the sharing of this information with the broad Plant Biology community is an important step toward the renaissance of this excellent plant model that will have important impact on our quest for sustainable development of the world.

These plants can recover nutrients such as nitrogen and phosphorus from contaminated waters in those agricultural practices. They can also remove or accumulate metals, radionuclides, and other pollutants in their tissues. In addition, the duckweed can be used as a feed source for livestock and poultry as well as an energy source for biofuel production. A summary of some of the published work done using duckweed species to phytoremediate natural, domestic, industrial, and agricultural wastewaters is presented.
